Steveo, what is a 'growstick' ? A special kind of bulb holder or something ?[/QUOTE]
Yes, you've got it. It's a domesticated shop light--just a low-profile plastic frame with a very small ballast and a 20W 12T growlight in it, plus a power switch. Very lightweight, not very bright. Two-prong plug.
I think I bought it at a Sears hardware store during that brief period when they were trying to cross-pollinate with a garden store chain. It works pretty well--the flytraps like it at a distance of about 6 inches--and if I could have found more of them they would be part of my terrarium design.
I also have a grow stick. I just picked it up a wal-mart. I will say that there is no comparison between the brightness of the grow stick and the two other 20 watt fluorescents that I have. The grow stick just doesn't compare.

Yeah--it's that miserable ballast. *Probably not super moisture-resistant, either. *However, the form factor is great and the weight is a real plus.
I tore the diffuser off the thing to get better light.

In reference to the original question: if the bulbs keep burning out, it's probably not the bulbs. *It's probably the fixture or the environment. *
The fixture could be shorting out or it could have some other defect. *
The environment (how you have it set up) could lend to poor ventilation and overheating or something like that...
Moderator Schmoderator Fluorescent fluorite, England
I started out with one of those round "floodlight" type of grow lights. I found out after I bought it was not really a plant light but just an incadescent light with some blue painted over it. It gets very hot! So needless to say that didnt last long. I now use only fluorescent lighting for my tanks...1 Gro-Lux and 1 cool white and they work very well. The fixtures are fairly cheap, easy to find, to put together and in most cases, to hang (although I'm fighting with a 4-foot fixture at the moment). The fluorescent tubes dont produce too much heat and last a long time AND dont cost a lot to run. And easy to connect to timers.
My 2-cents worth. :-)
Compact fluorescents (CFL's) all the way. I use eight of them to provide light for my entire CP collection, and they're doing great. [img]http://www.**********.com/iBhtml/non-cgi/emoticons/smile.gif[/img]
