Customer Reviews

Rated 5 out of 5 by 5 reviewers.
Rated 5 out of 5 by Best Price For Clear Bulb When I began to replace the fixture in my mothers kitchen she wanted something bright and not fluorescent. I choose canister lights with R40 bulbs. The 1100 lumens multiplied by five lights give off more than enough light and the 5000kelvin makes the light very distinguishable. was the best price and great service. The bulbs came with plenty of packing and no damage. December 25, 2014
Rated 5 out of 5 by Great product. LEDs are very bright and a good replacement for incandescent bulbs. The price was lower at 1000 bulbs than any other source. December 8, 2014
Rated 5 out of 5 by The product has great features for artwork. We are using several of these to illuminate art work; they don't heat up the room and because of the 54000K it shows correct colors in the art work. August 12, 2014
Rated 5 out of 5 by Very nice bulb! These bulbs are a very crisp 5000K and also very bright, seems to be more than 1100 lumens but I can use all the light I could get with a large kitchen with 4 cans. Will be buying more for the rest of the house! July 20, 2014
Rated 5 out of 5 by Very bright light This LED bulb is equal to the brightness of CF with 2000 lumens. It works great. Thank you. February 23, 2014
