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.

    Durable and efficient. The bulb gives off good light in a work space and satisfies the requirements of my health department for shatter-proof glass in prep areas
    At 75 watts, this Satco incandescent light bulb comes two to the package, making an economical purchase! This bulb has 710 Lumens, and is 130 V. The finish on this long lasting bulb is frosted.
    Excellent deal for two 75W bulbs. Their frosted finish ensures they're not excessively harsh on the eyes, and their 2-4 year life expectancy makes this a worthy investment.
    This75 watt light bulb costs less and is rated at 710 lumens. The bulb has a frosted finish and can be used with a dimmer light switch. We prefer purchasing bulbs here on the site because we do not have to waste time going to the store. These come in packs of 2.

    This two pack of lightbulbs is a great buy and can be used in any light that supports 70 watt bulbs. I like these for use within the kitchen because the bulbs last a long time and can stand up to heavy duty use,
    Nice soft light with the frosted bulb and came undamaged. Good in an overhead setting gives off a warm glow not overly bright but supposed to last well and durable!
    This Satco seventy-five watt frosted finish incandescent rough service light bulb two pack is exactly as described in the product description on the website. I was pleased the frosted appearance is not overwhelming and would order this again for certain. I would like to see additional bulk purchasing options available in the future.
