Customer Reviews

Extra brightness really helps!5
This bulb is excellent! I was already using a 27 Watt CFL with 5100K color temperature, replaced it with this one, and the extra brighness just made things better. Based on research I've read, in order to combat SAD, Seasonal Affective Disorder, you need to get the brightness in a room above 1000 Lux. These are the bulbs to use to do it. I haven't been able to find any other manufacturer that makes a brighter standard-base bulb with 5000K CCT (correlated color temperature) or higher (which is also recommended).

Be aware though, that the total component height is 7 inches from the bottom of the screw fixture to the top of the glass spiral. So you need about 6" of space for the bulb.

Pretty good but not great3
This is quite large and will not fit many fixtures. It is supposed to be high CRI (Color Rendering Index) but a Minolta spectrum tester shows a lot of green and it is deficient in red and blue. The 5100K is nice and it is overall a good value.

Good light, but has an annoying buzzing.3
I like the light this bulb gives off, but I found the buzzing too annoying to have by my desk. I'll install it in the cellar.
