Heat shields for Hps lights?

but some fans to suck hot air out above the heatshield.... or get a cooltube... how much space are we talking ? t-5's come in 2 ft versions and 4 ft versions.. they dont get hot but they put out less lumens then hps

This is partially true, the do put out less lumens. The 4'-8tube t-5 puts out 40,000 lumens the 400 watt hps puts out 43,000.

and tend to take up more space (horizontally) and cost alittle more...

This is inaccurate. The t-5 will allow you to use 2 more feet of your space for growing. You could hang it from the ceiling, it's only 3" tall instead of 8", and you can keep it closer to the plants because it doesn't get hot like the hid's. It doesn't cost more initially if you take into account the cost of air cooling the light, forget the fact that the bulbs last 5 times as long.

so you get to chose power/heat or settle for alot less heat and alittle less power

Dot darlin, you are wrong about the efficiency of the t-5's. I am running the t-5 side of a comparison with a 600 watt hid. You can get the t-5 fixture right on top of your plants so the 3000 lumen light difference to a 400watt is gone. Don't believe everything you hear, check it out. I have include a picture or two. VV
