Reducing heat from lamp

[jess_hawk]

Hey all!
I recently moved home from college and my terrarium (has 8 minis in it now, mostly Lepanthes) is now in my basement, mostly because it has the most consistant temperature of any part of the house. I am alotted one bookcase for my plants and my aquariums, so my 'chids got moved to the big shelf on the bottom. I have the same light on them as I did at school, a full-spectrum lamp, but the change in location from top shelf and directly across from a very enthusiastic A/C vent to bottom shelf basement with intermittent fans has resulted in a daytime temperature increase of four degrees. (from constant 68 to 68 at night and 72 day)

You wouldn't think that this would change things.
For most of my plants (I had four at school, four are brand new), it hasn't. In fact, my L. manabina seems to like it slightly better. My L. ovalis, however, hasn't been fully opening blooms or having as many blooms since I got home. (It is still growing and putting out flowers, just less intensely than before) I'm wondering if there is a way to decrease the heat they are getting from the lamp without decreasing the amount of light they are getting.

There is also the possibility, of course, that other factors, such as the change in air motion, is the cause of this change, and I will be tinkering with that, too.
