about what?

i do not have a cool tube or a glass...i just have a rack for cooling computer room it has 6 48 volt pc fans in it and it is placed rite beside my hood and it extracts the heat with no problem and my space 75 watts per sq.ft a 1000 watt mh and 5 1/2 ft of vertical space 5 1/2 ft long by 2 1/2 deep

So, if the cooltube footprint sucks that bad, how hard is it to make a reflector? Any diy links to making air-cooled reflectors? They are expensive, and I can't afford an extra $150-200 just for a nice reflector, I'll either stick with the cooltube or go for the cheapos that come with them on some sites that look like they were just folded over.

Would it be possible to not run an air cooled light and just have an in-line fan at the top to pull the hot air? If so, then I can definately find a reflector that would fit the bill. Maybe one of the octagonal looking ones that would help spread the light out properly.

Really, I will be finalizing the decision today/tonight, so I could really use some help from some of you with experience with lamps in rooms that around this size! Maybe your ambient temps and raised temps would help

I have a similar box. 4x2x4... I'm running 2 250w HPS with bat wings. I get good coverage, around 3000 ft/cdl on my meter, all around the box. I average around 1.25oz per plant and I can fit 6.

I have 2 AC 80mm 110v fans that have a high pressure rating mounted at the top of the one side, and then a 4in duct for inlet. I have negative pressure, enough to hold a piece of paper to it. Temps are around 78F with a room temp of 70F. I noticed on some days when the temp spiked I could get better cooling from turning off one of the fans.
