no, you'll be fine with the heat from one 400 watt, its when you get into the thousands of watts you need to worry.

So a 400-600 watt light would be ok in that space aslong its its well stealthed out and ventalated i should have no worries with the hot air in the attic being notices by over head heat sencors ?

Just get a filter and hook it up filter-cool tube-fan and exhaust it into the attic and you'll be fine. I like to over do fans so I'd be looking for at least 250cfm to get through the filter and pull the hot air out

ok im new to cool tubes i take it cool tubes are a extra peice of glass round the actual bulb it self that is hooked up to a duct leading straight to the filter straight to the exuast where it goes to the attic

right, or you can get a cooled reflector that won't necessarily have glass around the bulb but it'll still be air tight and have two ends for ducting
