40W, Frosted Finish

This 130V bulb is rated at 40W and emits 280 lumens for great illumination no matter where it's installed. Additionally, it boasts a frosted finish, which provides a softer look than a standard clear bulb. And because it's dimmable, you can also use it in fixtures where the light level can be adjusted as needed.

Customer Q&A Ask a Question

I installed this bulb and it doesn’t seem as bright as the one I was replacing. What gives?
This is a commercial/ industrial bulb designed to withstand power surges. While it will operate on a household 120 volt electrical connection, it actually requires a 130 volt electrical connection to produce the full rated lumens. The light lumen output will go down about 24% when used in a 120 volt circuit, but the life of the bulb will last 280% longer than it would in a commercial/industrial setting with a 130 volt circuit.

    Very very small. It is pretty bright for being small but it was almost an awkward size. Fits in fine on a desk lamp or something like that.

    Save money on these basic light bulbs. A very good deal. These bulbs are rated at 280 lumens and have a frosted finish. Great for household use.
    For a service bulb, it works great for a refrigerator at 40 watts. The base is brass, and the packing protects the bulb during shipment.
    This Satco forty watt frosted finish incandescent general service light bulb is exactly as described in the product description on the website.

    Nice light bulb for refrigerator or freezer for like a home for DeRitter it's not for Leica walk in it's just a nice little bulb for a pome refrigerator
    Our bakery blows light bulbs more than we would like due to it being an old building. We were very pleased when we saw webstaurant sold bulbs because we knew they'd be great and a great price.
    This is our first stab at Satco branded bulbs. So far they have been good and work as expected. The only downfall was that It seemed that it had been stored somewhere that allowed moisture to get on it. Other then that, happy with the purchase.
