opinions would be appreciated thanks

Here you can see a 1000 watt bulb in a reflector using a 720 CFM inline fan and a carbon filter can have plants 1/8 of an inch from the glass without burning the plants.... the light is on a light mover that moves about 20 inches

Here you can see 16, 1000 watt bulbs being cooled in "cool tubes" using a a 2000cfm inline fan.

And the third picture is 16, 1000 watt bulbs being cooled in reflector hoods using a 2000cfm inline fan....

They all work great

I would go with the cool tube, but only if you use a gavita bulb to reduce light loss. In fact, gavita bulbs are good with air cooler setups to keep them as efficient as possible.

air cooled hood, better footprint than the coolube

I'ld go with the reflector, I have a 600w air cooled reflector and the plants can touch it without burning (not that I try for that).

how close do you keep the light to the plants? I assume you use glass SHIELD?

This is correct. However, the tube can be suspended vertically with no reflector for a 360 degree vertical grow. Also, tubes can be modded with a large batwing reflector (more $$$) for better light spread.

hi what kind of light foot print does the cool tube leave compared too the reflector type ?
