40 watt light bulb appliance

Most 40W-equivalent appliance bulbs use the standard Edison medium screw base (E26) or the smaller candelabra screw base (E12).

In the data, incandescent appliance bulbs use about 40.0 watts, while 40W-equivalent LED appliance bulbs typically use much less—about 3.5 to 5.8 watts depending on the LED model.

Appliance-specific 40W bulbs are typically designed for the E26 medium screw base and are recommended for use in appliances. Reviewers also report that many of these bulbs fit and work in refrigerators, ovens, stoves and range hoods.

Based on the data, estimated annual running costs range from about $0.43 per year for some LED options up to $4.82 per year for a 40W incandescent appliance bulb; several LED models are listed around $0.61–$0.66 per year.

Typical light output is about 415–450 lumens: for example, an A15 appliance incandescent lists 415 lumens, while many A19 LED options list about 450 lumens.

Incandescent appliance bulbs in the data list about 1.4 years of life, while many LED 40W-equivalent options are rated around 13.7 years, with some LED models listing up to 22.8 years.

Common color temperatures listed are 2700K (warm/soft white) and 5000K (daylight). LEDs commonly report CRI values around 90–95, while an incandescent listing shows CRI 99.

The listings commonly show A15 and A19 shapes for appliance bulbs, and smaller candelabra-style BA11 shapes also appear.

Many 40W-equivalent bulbs are full-range dimmable. Some color-changing or decorative models include remote control or app/voice features for color control and scheduling, while a few decorative bulbs are one-way (on/off).
