Customer questions about this product

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.
    This 40 watt bulb has good brightness. It's has 2500 hours life time and price is affordable and shipping was fast and safe with lots of wrapped. Thank you.
    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. I was satisfied the frosted appearance is not overwhelming and would order this again for certain. I would highly recommend for commercial or residential use.
    Bought this bulb to light up my bathroom mirror and it's the perfect amount of brightness. I was impressed by its 2500 hour life expectancy.
    Satco S3811 40 Watt Frosted Finish Incandescent General Service Light Bulb - 130V (A15) is unusually bright and nice looking despite it only being 40 watt. Good buy.
    This light bulb is perfect for my range hood. Its isn't too large and has a long life span. Obviously can be used for many other things as well...
    The Satco S3811 40 Watt Frosted Finish Incandescent General Service Light Bulb - 130V (A15) works great! I did not know that webstaurant.com sold them. Not only do they sell the bulbs, the price is very reasonable. No issues with the bulb and its a great value. Highly recommend!
    If you need this type of lightbulb, regardless if you're a business or it's just for a home, this is a good place to buy it from. Good price.
    nice light bulbs for a great price, they work well, they are really bright, not a problem, because of the cost, i can replace them easy!
    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.
