Rated 5 out of 5Â by Argon532 Terrific lights - I have not tried these on a dimmer
Length of ownership: 6 months
Total bulbs: 9
Failures or defects: none
Setting: indoor and garage
Fixtures: mix of completely enclosed (no air circulation) and open
Power consumption: 9.9 watts with moderate use
Quality of light: Very bright daylight glow. These lights are cooler (whiter) than regular incandescent lights. Great for areas where good lighting is needed.
Performance: Instant on, subjectively seems more like a 100W incandescent bulb
Omnidirectional? Yes, see pictures.
Dimming: have not tested but I also have the 2700k version which works terrific when dimmed
Issues: None, but I have not tried them on a dimmer.

Rated 5 out of 5Â by SusieQ May have to upgrade old dimmer switch
Contrary to other reviews, these bulbs DO NOT buzz and dims well with the new SETABLE Dimmer switches on the market today. I suspect the reviewers are not upgrading their dimmer switches to be compatable with the new dimmable LEDs & Fluorescent bulbs. The Daylight bulb is the brightest!

Rated 5 out of 5Â by mike Works as expected. Very bright even in the can lights.
I was a little concerned about the 'spotlighting' of LEDs but read about the CREE tower technology and decided to give it a try. I am more than happy with the purchase. The only question will be long term functionality. American made company. CREE makes LEDs that are recommended for coral reef aquariums. If they are trusted there, I have confidence in the quality.

Rated 5 out of 5Â by AndrewGSTX Great American made product!
I'm so happy that Home Depot is carrying these top-quality American made Cree LED bulbs! I've bought 4 so far and plan to buy more until my entire house is filled with them. Bright white light is an understatement. I've never seen such an efficient LED bulb and the price can't be beat. The photo I've posted is of 3 of these bulbs on the front of my house consuming only 27 watts.

Rated 5 out of 5Â by GCGirl77 The Math - Savings & Break Even Point
Because I'm a nerd:
100 watt light bulb burning for 10 hours = 1000 watts = 1 kwh
Our current utility price per kwh in Northwest Indiana = $0.11
Cost of light bulb six pack including 7% sales tax = $85.41
Cost for one light bulb from the six pack = $14.23
Watts used by new light bulb = 9 Watts
Watts used by comparable light bulb = 60 Watts
Wattage savings (difference) per hour = 51 Watts
Hours it would take at a rate of 51 watts per hour to equal 1 kwh = 19.61 Hours
Cost of light bulb divided by cost of 1 kwh equals number of kwh to break even point = 125.15 Kwh
Number of total kwh need multiplied by the number of hours per kwh at 51 watts= 2453.89 Hours
Total number of hours divided by 3 hours per day usage = 817.96 Days
Total number of days divided by years equals break even point for cost of light bulb = 2.24 Years
Lifespan of new bulb based upon 3 hours per day usage = 22.8 Years
Lifespan minus years to break even = 20.56 Years
Total savings of 51 watts per hour at 3 hours a day for 20.56 years at $0.11 per kwh = $126.29
Total savings for 6 bulbs replaced over their lifespan = $757.76
Savings does not include the cost of incandescent replacement bulbs during the length of 22.8 years nor does it take inflation or rising utility costs into consideration.
