Pros: Good, crisp light...eventually
Cons: Too bright at full power, takes too long
I got one as a free gift, the enclosed indoor CFL. I already use a different brand of CFL everywhere else in my house, and they are on the dim side, but I don't need much light at night. In fact, the only reason I turn on lights is to find something I'm looking for or if I'm in the bathroom or kitchen. This is where the problem is, I first put it in my office and if I need to find something in there, I would have to turn on the light, then walk away and do something else for a little while, then come back after the bulb is fully bright. It's not just dim, I can barely tell that it is on sometimes. When it is fully bright, it is almost too bright. I guess it could come in handy if I was sewing at night, but it kind of gives me a headache, and my fiance actually stopped using the light at all and just started lighting candles.
It is now in my laundry room, because I ran out of my other lightbulbs and this was the only one I had left. To give some perspective: I can turn on the switch, move the clothes from the washer to dryer, add a new load to the washer, start both and the light is still too dim for my taste. I'm sure it is extremely eco-friendly, but it kind of defeats the purpose if I have to leave the light running for a minute before I can use it. In my opinion there are some better options and I would never purchase one of these.
