GE Daylight Energy Smart Spiral T3

I believe that the first group of these light bulbs I got were Sylvania, and there was a short delay before they would come on. The GE seems to come on a biy faster. But I have lost nothing by switching!

 I replaced about half of our home's bulbs with this, We have a new home and it's amazing how many lightbulbs they manage to put in! You figure, cutting from a 60 watt bulb to a 15 watt, that's a quarter of the power! And I have not noticed missing "light" from our home. Granted they aren't cheap yet but they aren't bad!I think this is a GREAT product!

Before you purchase these bulbs, make sure they're what you're looking for.

As bulbs have been burning, I've been replacing them with CFLs. When I was picking up a four pack of new bulbs a higher quality 'daylight' model seemed like a good idea. Who doesn't want to use more 'sun-like' light whenever possible? Well...when installed them near other rooms with more traditional 'soft' lights installed, it's quite hilarious. People actually made comments like 'is it still daytime in the other room?' and 'do you have a tanning salon in there?' I think if the entire home used this style of light, it'd be great but it doesn't work well when mixed. I'd recommend trying them in a more isolated room/area and see what you think. It might take some adjustment to get used to the type of light.

Besides that, they're great. They're install like any other bulb, run cooler, use a lot less energy and last longer. No one should buy anything but LED and CFLs whenever possible.

I am a grad student, so I don't have many lights in my apartment to begin with. Even so, I bought one, for the lamp I most often use. As they are more expensive than the regular light bulbs, I have only bought one so far. The good thing is that my lamp now runs much cooler than with my previous bulb (which got quite hot). It also turns out that these are very bright. I don't really need another lamp to light up my room they are so bright.

The downside: if I look into the light, I feel "blinded" so to speak. Otherwise, I like what I see.
