Rated 5.0 out of 5 by 5 reviewers.
Rated 5.0 out of 5.0 by Good light Good quality of light from the bulb. I've gotten other led bulbs for retrofit recessed lights, bi-pins and candelabra base. the color temperature description is accurate and warm. A little wider and taller than a traditional bulb, of corse heavier. I have two installed in a floor lamp facing up by a set of stairs. The frosted glass helps to diffuse the light from the individual LEDs so you see a ring of light going around the bulb. Using the dimmer on the lamp the intermediate light setting has some flickering. January 1, 2014
Rated 5.0 out of 5.0 by High Quality Product Recently purchased these bulbs for my work-shop. It is an unconditioned space with ceiling mounted utility cage lights, and I was replacing incandescent bulbs on a monthly basis most likely because of the extreme temperature changes. The light quality is excellent, very similar to the warm feel of incandescent lighting, and I have not had any issues with burnt out bulbs. Decided on purchasing the Swith bulb over competitors because they can be used on any fixture and in any orientation. I believe that other LED bulbs will burn out over time if they are mounted in a closed fixture with the base up....these will not. Overall very pleased with the light output and build quality of the bulb. December 10, 2013
Rated 5.0 out of 5.0 by Excellent Quality Very, very happy with the build quality of this product. The light quality is also outstanding. After trying other LED bulbs, I now plan to be using only Switch bulbs in the future. January 12, 2014
Rated 5.0 out of 5.0 by price coming down, whiter light The price for 100w equiv LEDs is still very high, but coming down. Good for high usage areas only. 3000° color temp is whiter (and brighter looking) than usual incandescent. Cost-effective if it lasts as long as mfr. claims. March 11, 2014
Rated 5.0 out of 5.0 by Simply the best 100We 100 We LED bulbs are less common. I have looked at them all and this is the best looking, best performing by a wide margin. If an LED bulb last many years -- then this is the one to live with. January 22, 2014
