100W Equivalent Cool White A21 Clear LED Light Bulb is rated 5.0 out of 5 by 5.
Rated 5 out of 5 by from Excellent source of light I was looking for an energy efficient source of light to replace the old incandescent and ran across this brand of LED replacement bulbs. I must say what an eye opener....literally. It's like daylight in my home now. I replace a 100W standard with this 20W equivalent and holy smokes....what have I been missing. Best $ I've spent. Greatly recommend.

Rated 5 out of 5 by from Added Bonus I got these for longer life and lower cost to operate than my current incandescent bulbs. I dropped one getting it out of my cabinet. It fell on my washing machine then bounced on the floor. I just knew that bulb was ruined. I picked it up, screwed it in and it worked. I will be using them in my shop lights, what a durable bulb.

Rated 5 out of 5 by from Outstanding LED lightbulb You can not go wrong with this bulb. I have 60/75/100 and three ways in my house and all are fantastic. They light up immediatly and provide bright warm light. I have used other LED's and while some might be comparible, there is a clear difference in the quality and performance of this bulb. Enjoy!
