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.

    This 40 watt light bulb is a good quality and low priced bulb. It has a frosted and shatterproof finish and can be used with dimmer switches. We love buying our bulbs online. Saves us a trip to the store.
    This Satco forty watt frosted shatterproof finish incandescent rough service light bulb is exactly as described in the product description on the website. I was pleased that the yellow color is not overwhelming and would order this again for certain. I would highly recommend to anyone.
    We needed shatterproof lights in order to comply with health code regulations. Was very happy to see webstaurant carried these. Lower watts with the 40. But still good lighting.
