I have a digital one, which is mounted in there, temps are in the lower 80's.

The hps actually doesn't put off as much heat as i thought it would, the 85 watt cfl, puts off the same amount of heat really.

The room everything is a rather cold room, outside temp is in the lower 70's in the day, and upper 60's at night. That is why i installed the temperature probe in there, the day of the hps install.

So temps are in check :-). But i have noticed that it is much warmer in there with the addition of the hps, and the 85 cfl. I will have to keep a eye on the temp, on the hot days outside.
