The bulb is described as resistant to temperatures up to 570°F, making it suitable for use in ovens, refrigerators, under microwaves, over-stove range hoods, and even lava lamps. Its specification also lists numerous OEM and legacy bulb references, including 15206, 48706, 83645, 40A15, 4396822, 8009, 10181, 10034, 9570, and 5032-6. That broad reference list is helpful when the old bulb has lost its identifying markings.
The trade-offs are modest but real. This is a single-bulb pack, so buyers who want a spare will need another purchase. It also has the lowest customer rating in this list at 4.3, although that remains a positive score, and the product description alternates between 500-degree language in the title and a 570°F specification. Buyers should treat the detailed 570°F specification as the stronger technical reference while still following the appliance maker's bulb requirements.
This is a good pick for anyone replacing a standard 40W A15 appliance lamp without needing a model-specific part. Verify the socket, voltage, and bulb clearance, then confirm that the replacement is permitted for the specific oven. It is especially useful for people who want warm light, a familiar E26 base, and compatibility with several common appliance fixtures in one compact bulb.
Compact Shape for Limited Appliance Clearance
The listed dimensions are approximately 1.9 inches wide by 3.3 inches high, matching the standard A15 format. That profile is particularly helpful when a larger G45 bulb may not fit inside a shallow appliance cover or lamp housing.
Useful Legacy Part References
The long OEM-reference list gives owners a practical way to cross-check an old bulb before ordering. Matching a listed part number is useful, but it should still be confirmed against the appliance manual and the socket's physical requirements.

We may earn a commission when you buy through this link, at no additional cost to you.
Heat resistance up to 570°F is the central feature, supporting use in demanding appliance environments such as ovens, oven hoods, microwaves, refrigerators, and ceiling fans. The listed lifespan of approximately 2,000 hours per bulb is also the longest stated figure among the two-packs in this roundup. A lead-free base adds another practical detail for buyers comparing traditional appliance lamps.
Its main limitation is that the specifications do not mention dimmable operation, so it may not suit appliance controls that require a dimmable bulb. Like the other conventional entries, it uses incandescent technology rather than an LED module. Its two-bulb pack is suitable for keeping a spare on hand, though the fourth G45 option offers a larger four-pack for shoppers who regularly replace appliance lamps.
This is a strong general recommendation for a standard 40W E26/E27 appliance socket. It suits buyers who value a well-reviewed two-pack, recognizable wattage, warm illumination, and stated high-temperature capability. Confirm that the appliance accepts a G45 incandescent bulb and check the fit before ordering.
A Spare in Every Two-Pack
Including two bulbs is useful for immediate replacement plus one future spare. It also allows owners of matching appliances to replace both lamps at the same time without ordering separately.
Clear Warm Illumination
The clear finish preserves the familiar appearance of a traditional incandescent appliance bulb, while 400 lumens provides practical visibility inside an oven cavity or beneath a range hood.

Its brass base and special silicone seal are highlighted as features that improve heat dissipation and durability. The product is stated to withstand 300°C, or 570°F, and is marketed for ovens, microwaves, refrigerators, and other household lighting. The stated life is up to 1.7 years, and the lead-free construction is another point in favor for users seeking a conventional appliance lamp.
The supplied information is not entirely consistent. The title states 415 lumens, while the bullet points refer to 400 lumens, and one bullet also contains mismatched wattage wording even though the product identity clearly centers on 40 watts. Buyers should use the complete model listing and package details to confirm output. The dimmability claim also depends on the appliance's controls supporting that function.
This pair is a sensible option for G45 sockets that accept a dimmable 40-watt incandescent bulb. It is particularly attractive for buyers who prioritize heat dissipation, a brass base, and two included lamps. As always, compatibility with the appliance should take priority over general household-lighting flexibility.
Heat Management Through Base and Seal
The brass base and silicone seal are the distinguishing construction details. They are intended to release heat effectively and support longer service in hot appliance locations.
Control Flexibility for Compatible Appliances
Dimmable operation can be helpful when an appliance offers multiple brightness levels. The feature is useful only when both the bulb and the appliance's control system support it.

We may earn a commission when you buy through this link, at no additional cost to you.
The bulbs are rated to withstand 570°F, or 300°C, making them appropriate for ovens, ranges, and stoves when permitted by the appliance manufacturer. Special seal silicone is used with the socket to support heat dissipation, durability, and a listed life of 1,500 hours per bulb. The package contains four bulbs, making it convenient for several appliances or a well-stocked household replacement supply.
The trade-off is that four bulbs may be more than a single-appliance owner needs. The physical size is listed as approximately 2.76 by 1.77 inches, so buyers should ensure the G45 shape fits the cover and socket. The product also specifically calls for an E26 socket, making fitment verification important even though the broader base designation includes E27 compatibility.
This is the premium pick for households that maintain multiple ovens or stoves, operate appliances frequently, and prefer to keep several replacements on hand. Its combination of four bulbs, 415-lumen output, and stated heat resistance also makes it a straightforward choice for 40-watt G45 fixtures. Verify the appliance's bulb specification before installation.
Four Bulbs for Multiple Appliances
The four-bulb quantity is the clearest reason to choose this option. It can cover several matching fixtures or reduce the need for frequent repeat purchases.
Practical Brightness for Appliance Interiors
At 415 lumens, the listed output is among the stronger conventional figures in this comparison. That level of light is useful for checking food and viewing the interior of a large oven.

We may earn a commission when you buy through this link, at no additional cost to you.
The E26 base and clear incandescent design are straightforward to match against a standard appliance socket. The bulbs are described as dimmable and compatible with most dimmer switches, which gives them some flexibility in household fixtures. A two-bulb pack provides an immediate replacement and a spare for another compatible appliance.
The most important limitation is that the supplied product information does not state a maximum heat-resistance rating or a specific rated lifespan. That matters because an appliance bulb is expected to tolerate heat in its installed environment. This product may be suitable where the manufacturer permits a 40-watt A15 incandescent bulb, but the absence of a stated thermal rating makes it less informative than several high-temperature options in the guide.
This pick is best for standard A15/E26 appliance sockets where heat specifications are not a deciding issue or where the appliance manufacturer explicitly recommends this type. Its 4.6 rating, compact form, and dimmability are compelling, but owners should still check the appliance manual before installing a traditional incandescent bulb in a hot location.
Recognizable Traditional Bulb Format
The A15 shape, clear finish, and E26 base are familiar to many appliance owners. That familiarity makes the option easy to consider when replacing a matching 40-watt bulb.
Soft White for Comfortable Visibility
The 2700K warm-white output offers a softer appearance than stark daylight bulbs. It remains bright enough at 415 lumens for practical appliance illumination.

We may earn a commission when you buy through this link, at no additional cost to you.
Its voltage range is listed as 110 to 130 volts, which covers standard household appliance power in the United States. The product is intended for ovens, oven hoods, ranges, microwaves, refrigerators, night lights, sewing machines, and other small appliances. The listed bulb dimensions are approximately 3.5 by 2.2 inches, so owners should compare them with the available space in the appliance cover.
Unlike several competing options, the supplied information does not provide a lumen figure. That makes it difficult to compare brightness directly. Its advantage is instead the combination of a high stated lifetime and heat resistance. Incandescent bulbs still lose efficiency through heat and have a finite service life, so the 2,500-hour figure should be treated as a rated characteristic rather than a guarantee.
This is a good selection for a compact A15 socket that accepts a 40-watt incandescent bulb and where long rated life is important. It is especially relevant for a refrigerator, range hood, sewing machine, or smaller appliance. Confirm that the appliance allows incandescent operation and that the bulb will physically fit before ordering.
Long Rated Service Life
The stated 2,500-plus-hour life is the strongest longevity figure in this selection. That can be useful in appliances where frequent bulb access is inconvenient.
Compact A15 Geometry
The A15 format is smaller than many G45 alternatives, which can make it easier to fit beneath a narrow cover. Measuring the old bulb and available clearance remains essential.

300°C heat tolerance
This G45 appliance bulb has a 4.5 rating and combines a standard 40-watt rating with dimmable operation. It produces 360 lumens of warm white light at 2700K, making it a practical option for fixtures that do not require the highest lumen output in this comparison.
Pros
- Dimmable brightness control
- E26 brass base
- 300°C heat tolerance
- Broad fixture compatibility
- Lead-free construction
Cons
- Lower lumen output
- Only 360 lumens listed
We may earn a commission when you buy through this link, at no additional cost to you.
The bulb uses an E26 brass base, and the listed temperature resistance reaches 300°C, equivalent to 570°F. Its applications extend beyond an oven to microwaves, refrigerator and range-hood lights, garden fixtures, wall sconces, hanging lamps, porch lights, and lava lamps. That flexibility is useful, although the appliance manufacturer should approve its use in any oven or microwave.
The primary drawback is that 360 lumens is lower than the 400- or 415-lumen figures advertised by several alternatives. This may not matter in a small appliance or under a hood, but it could make a large oven cavity feel dimmer. The product information also contains some typographical errors, so buyers should rely on the model listing and package rather than assume every descriptive phrase is precise.
This bulb is well suited to owners who want a dimmable, heat-resistant G45 lamp that can serve several household fixtures. It is less compelling for maximizing brightness, but the 2700K output and broad application list remain useful. Confirm the socket, wattage, and dimmer compatibility before purchase.
Adjustable Light for Different Settings
Dimmability can make a shared appliance bulb more adaptable. It also allows a user to reduce glare when a full 40-watt output is unnecessary.
Brass Base for Heat Dissipation
The brass base is intended to handle heat more effectively than some conventional bases. It complements the bulb's stated 300°C resistance rating.

- Requires model verification
We may earn a commission when you buy through this link, at no additional cost to you.
The part number WB08T10002 is also associated with AP2019709 and a list of replacement references, including 769452, AH230438, EA230438, PS230438, WB02T10115, WB02T10116, WB08T10044, WB2T10115, WB2T10116, and WB8T10002. Compatible model numbers are provided, including 91163278891, 91192496891, 91141485890, JDS28CK1CC, JGSP28WEK4WW, JGSP28CEK4CC, JTP15BA1BB, 91147814202, 91145468095, and JSP40BW4BB.
The LED design is described as energy saving, durable, and long-lived. Its IP65 protection, one-key switch, and lightweight portability make it distinct from a simple incandescent bulb. The crucial trade-off is fitment: this assembly will not suit a buyer who only needs a standard E26/E27 appliance bulb, and the supplied compatibility list cannot account for every production variation.
This is the right choice for a compatible GE or Kenmore wall oven whose indicator or cavity light assembly has failed. Before buying, compare the assembly, connector layout, model number, and mounting method with the failed component. Disconnect electrical power before installation and wear work gloves, as directed by the product information.
Purpose-Built for Selected Ovens
Unlike a universal incandescent bulb, this assembly includes the light and indicator components expected by certain wall-oven designs. Exact model matching is therefore more important than checking a generic socket type.
Efficient LED Indicator Design
The LED approach offers a durable, energy-saving alternative to a conventional appliance bulb. Its sealed housing and IP65 protection also distinguish it from an exposed screw-in lamp.

We may earn a commission when you buy through this link, at no additional cost to you.
The stated dimming range is 10 to 100 percent, making it more flexible than several other conventional choices. Color rendering is listed as CRI greater than 90Ra, which should provide vivid, natural-looking color. Its listed life is 1,500 hours, and the product is described as free of mercury and lead.
It is advertised for ovens, refrigerators, microwaves, over-stove fixtures, and range hoods, as well as floor lamps, table lamps, ceiling lights, garden lights, hanging lamps, and wall lamps. However, the supplied specifications do not give an exact maximum operating temperature. That omission matters for a hot oven installation, so the appliance manual and bulb requirements should be checked before purchase. The 360-lumen output is also lower than that of several competitors.
This bulb is a compelling choice for a compact fixture that supports dimming and values natural color rendering. It may also be useful beyond the oven for compatible household lighting. It is less suitable as an automatic selection for an extreme-temperature appliance location without confirming the manufacturer's approved bulb type.
Detailed Brightness Control
The listed 10-to-100-percent dimming range offers more control than a simple on-off bulb. It is useful with compatible dimmers and appliance controls.
Compact Dimensions with Natural Rendering
At approximately 1.89 inches in diameter and 3.35 inches in height, the A15 body fits many compact fixtures. The stated CRI above 90 supports clearer visual inspection of appliance contents.

We may earn a commission when you buy through this link, at no additional cost to you.
The brass base is highlighted for reliable, extended use, while the E26/E27 medium base makes the bulbs familiar to owners replacing standard household appliance lamps. Two bulbs are included, which gives buyers an immediate replacement and a spare. The clear G45 format is suited to fixtures that have enough clearance for a traditional globe-style appliance bulb.
The supplied information is less complete than for several competing products. The dimensions section ends without a stated maximum overall length, and there is no mention of dimmability or a precise rated lifespan. Those omissions do not invalidate the core electrical and thermal specifications, but they make physical fitment and control compatibility harder to evaluate in advance.
This is a solid selection for a standard high-heat G45 socket where 415-lumen brightness and a two-bulb pack are priorities. Measure the fixture, confirm 40-watt and 120-volt requirements, and ensure the appliance manufacturer permits an incandescent replacement. For buyers who need a stated lifespan or dimming information, one of the more thoroughly documented alternatives may be easier to assess.
Bright Conventional Output
The listed 415 lumens places this bulb among the brighter options in the guide. That output is useful for larger oven cavities and range fixtures.
Heat-Tolerant Brass Base
A brass base supports heat dissipation in demanding locations. Combined with the stated 570°F resistance, it gives this two-pack a clear thermal-design focus.

Buying Guide – How to Choose the Best Oven Light Bulb Replacement
A successful replacement depends on more than choosing a bright bulb. The correct product must fit the socket, match the appliance's electrical requirements, tolerate its operating environment, and provide light without interfering with any dimming or indicator system.
Confirm the Bulb Shape and Dimensions
Bulb shape determines how the lamp fits inside a fixture. A15 bulbs are compact and commonly used in smaller appliance housings, while G45 bulbs are wider, globe-style replacements. The listed choices include A15 products measuring approximately 1.89 to 1.9 inches in diameter and around 3.3 to 3.5 inches high, while G45 options are generally larger. A socket can accept an E26 screw base and still lack enough room for a wide G45 envelope. Remove the old bulb or inspect the appliance manual, compare its dimensions, and allow clearance around the glass and base.
Match the Base and Socket
Most universal appliance bulbs in this guide use an E26 medium base, with several also described as E26/E27 compatible. E27 is the larger international screw size, so a product naming both does not mean it will physically fit every socket in a different region. The appliance manufacturer may specify a particular base, wattage, and model-specific part. A lamp that appears similar can still fail if its threads, contact, shoulder, or housing geometry differs. For the WB08T10002 LED assembly, compatibility is instead based on a part number and a defined list of wall-oven models rather than a screw-base size.
Verify Wattage and Voltage
The conventional products in this roundup are 40-watt incandescent bulbs designed primarily for US household appliance systems. Most state 110 to 120 volts or 110 to 130 volts, while the model-specific LED assembly follows the requirements of its listed oven models. Voltage must be compatible with the appliance, and wattage should match the original specification. A brighter bulb is not automatically safer or more suitable: excessive power can create heat, reduce component life, or exceed what the fixture and wiring are designed to support. If the appliance manual specifies a wattage, use that value rather than relying on a general marketplace listing.
Evaluate Heat Resistance
Heat resistance is a defining requirement for bulbs used near an oven, microwave, range hood, or over-stove fixture. Several products in this guide are rated for 570°F, or 300°C, while the GE A15 option does not provide a thermal figure in the supplied information. A listed heat rating indicates that the bulb is designed for the stated environment, but it does not override the appliance maker's instructions or guarantee unlimited service life. Actual life depends on installation position, vibration, switching frequency, temperature exposure, and voltage. A lamp installed inside the hot cavity should meet the manual's requirements; a lamp under a hood may face less direct heat but still benefits from a proven high-temperature construction.
Compare Light Output and Color
The listed conventional bulbs produce 360, 400, or 415 lumens, depending on the model. The 415-lumen products may feel more useful in a large oven, while 360 lumens can be adequate for a refrigerator, range hood, or compact fixture. Most offer warm white light around 2700K, creating a softer appearance than a cool daylight bulb. One A15 option states CRI greater than 90Ra, a useful color-rendering detail for people who want food and appliance contents to appear natural. Brighter output should be evaluated alongside clear glass, bulb size, and appliance design rather than treated as the only measure of quality.
Check Dimmability and Controls
Some appliance lights operate on low, medium, and high settings, and several bulbs in this guide are described as dimmable. That does not guarantee compatibility with every oven control. The appliance must support dimming, the fixture must use the appropriate control, and the replacement may need to match the expected incandescent or LED load. The Visther G45 and the A15 options listing 10-to-100-percent dimming are explicit about this feature, while some alternatives do not make a dimmability claim. If compatibility is uncertain, the safest approach is to follow the manufacturer's bulb specification rather than assuming a common dimmer will work.
Consider Lifespan and Pack Size
Rated life helps estimate replacement intervals, though it is not a guarantee. The supplied figures range from 1,500 hours to more than 2,500 hours, with one product also described as having a 1.7-year life. Pack size ranges from one to four bulbs. A two-pack is convenient because it includes a spare, while a four-pack makes more sense for households with several matching appliances or restricted access to the fixture. Choosing the correct number can reduce repeated maintenance, but buying more than needed may leave unnecessary spare bulbs in storage.
Distinguish Universal Bulbs from Model-Specific Parts
A standard E26 appliance bulb is appropriate when the appliance manual calls for a 40-watt A15 or G45 incandescent replacement and the physical socket matches. A model-specific LED assembly is appropriate when the original component is an integrated wall-oven light or indicator. The WB08T10002 includes a defined set of GE and Kenmore model references, but fitment can vary by production run. A universal bulb is easier to match broadly, while a specialized assembly offers a more integrated installation. Neither category should be forced into the other: compare part numbers, connector design, voltage, wattage, and physical dimensions rather than relying on the words oven light alone.
How to Use and Care for Your Oven Light Bulb Replacement
Before replacing a conventional bulb, switch off the appliance, unplug it if safe and appropriate, or shut off the relevant breaker. Let the oven and lamp cool completely. A hot bulb and hot glass can cause burns, and fitting a cold bulb into a warm fixture may create unnecessary thermal stress. For a wall-oven indicator assembly, disconnect electrical power before installation and wear work gloves as directed by the manufacturer.
Remove the old bulb gently by hand unless the appliance instructions specify a cloth or suitable protective glove. Do not use excessive force, and avoid damaging the socket threads or contact. Confirm that the new bulb has the required shape, base, wattage, voltage, and temperature rating. Install it without overtightening, then restore power and test the light at the appliance's available brightness settings.
Use the replacement only in a compatible fixture and within its stated operating conditions. Inspect it periodically for darkened glass, discoloration, looseness, unusual dimming, or a broken base. Replace a damaged bulb promptly, avoid touching the glass unnecessarily, and keep grease and debris away from the socket. Always consult the appliance manual when its instructions differ from the replacement bulb's listing, especially for a model-specific LED assembly.
Frequently Asked Questions
Are all oven light bulbs interchangeable?
No. Oven light bulbs can differ in shape, base, wattage, voltage, temperature rating, and dimming requirements. The appliance manual and the markings on the old bulb are the best starting points for identifying a replacement. A standard E26 bulb is not automatically compatible with a model-specific LED assembly, and a compact A15 bulb may not fit where a G45 shape is required.
What is the difference between an A15 and G45 oven bulb?
A15 bulbs are narrower and more compact, which can make them easier to install in limited appliance spaces. G45 bulbs are wider, globe-style lamps that generally require more clearance around the glass. Both can use a medium screw base in many installations, so the base specification alone does not guarantee that the bulb will physically fit.
What temperature should an oven light bulb withstand?
The correct rating depends on the appliance and the bulb's position within it. Several products in this guide are rated to 570°F, or 300°C, but that figure should be checked against the appliance maker's requirements. Never assume a bulb is safe because it is marketed for an oven; follow the manual and use a recognized high-temperature appliance bulb where required.
Can I use a dimmable appliance bulb in my oven?
Only if the appliance's control system and bulb specification support it. Dimming behavior varies among incandescent and LED bulbs, and a dimmer designed for one type of load may not work with another. If the old bulb was dimmable, matching its type and electrical requirements is the safest starting point, subject to the appliance manual.
Are LED oven light bulbs better than incandescent bulbs?
LED bulbs can offer lower energy use and longer service life, but they are not automatically compatible with every oven. Many conventional oven sockets and controls were designed around 40-watt incandescent bulbs, while integrated LED assemblies may fit only specific models. The best choice depends on the appliance's required part number, electrical design, and operating temperature.
Why does my replacement oven bulb dim or shut off?
Possible causes include an incompatible wattage, a bulb that does not support the appliance's dimming system, an improperly seated base, a damaged socket, or excessive heat. First compare the new bulb with the old one and confirm the appliance specification. If the new bulb behaves normally in a compatible fixture, inspect the socket and consult a qualified appliance technician for electrical faults.
Should I replace both oven bulbs at the same time?
If the bulbs are the same age, have the same wattage, and are both near the end of their rated lives, replacing them together can simplify maintenance and provide more consistent illumination. However, it is not necessary if the second bulb is new, operates normally, and matches the appliance's requirements. A multipack can conveniently include a future spare.
Can I install a replacement bulb while the oven is still hot?
It is safer to turn the appliance off, disconnect power when appropriate, and allow the lamp and housing to cool before touching them. Hot glass can crack if cooled unevenly, and a hot bulb can burn your hands. Follow the appliance manual's specific removal procedure and use protective gloves if the manufacturer recommends them.
Final Thoughts on Choosing the Best Oven Light Bulb Replacement
The Appliance Oven Light Bulb A15 40W is the most versatile compact option, the SouLight G45 two-pack is a balanced budget choice, and the four-pack G45 high-temperature option is the strongest maintenance-oriented premium pick. Each offers a standard medium base and 2700K-style warm illumination, but the exact shape, output, and quantity should determine which one fits the appliance best.
Prioritize the appliance manual before any other feature. Confirm the required bulb shape, base, wattage, voltage, heat exposure, and dimming behavior. A model-specific LED assembly is appropriate only when its part number and oven model match, while a conventional 40-watt bulb works when its listed specifications align with the socket and environment.
Current prices, seller availability, customer feedback, and product details can change, so check the latest listing before purchasing. Comparing the present specifications, the replacement's physical size, and the appliance's requirements will help avoid an incorrect fit or an early failure.
