I don't even use cool tubes, or anything like that. I have played around with a sheet of plexiglass hanging directly under the lights as a direct-heat barrier, but not really sure it helps much. Still adds to the ambient temperature.

The quake was in northern Nevada. I'm just south of southern Nevada, (Arizona) and didn't feel a thing.
No worries, my friend. You're apparently doing very well without all the extra goodies, so that's something for me to aspire to, too. I don't grow for profit, same as you I just do it to share with my wife and a few close friends, but there's still something in me that's always wanting to try the latest and greatest gimmick on the market... as opposed to sticking with what works.

I've never built a cooltube either, because I've got an array of different sized lights laying around. I have, however, used a Cool Sun hood from Sun Systems, and when air-cooled, these things work awesome. If you ever decide to invest in a sealed reflector, I'd highly recommend one of these.

Glad to hear the quake didn't rattle ya around! Take care.
