Floodlight solution for growbox

4ft tall. 2ft wide. 1.5ft deep.
=3 sq. ft.

I'm planning to build a box using an HID floodlight (MH & HPS). I've read that floodlights are not recommended because the assembly gets too hot.

But what if I put the floodlight in a separate chamber and only the glass is exposed. It might even be cooler than just having a home made reflector+light because the glass will shield the grow area against the heat. The chamber holding the floodlight assembly will get hot, so I plan to put 2 fans and also put holes on the floodlight casing for vent.

Need your inputs before I finalize the construction.

Notes:
1. I drew a 9" line from the light. This would be the distance from the tips of the plants to the lights. It will leave me 23.75" of clear grow area.

2. The bottom part holding the plants will be height adjustable- since the light is fixed already.

3. I am limiting the height to 4ft. and maybe even shorter so I can "stack" 2 boxes together. I want to fit the most number of boxes in a small room and still be stealth.

4. The upper chamber will exhaust the air out through the back. There will also be a lower vent at the bottom (covered by pots) to let the air in.

5. I plan to also put activated carbon/charcoal on the upper chamber to somehow control odor before the air vents out.

6. It has a door. Just didn't draw it.

dunt know about the light, but i would use intake fans near the bottom, then as it warms up inside the box it will rise and exit via second chamber.

would the floodlight(s) but out enough light/lumens and what sort of spectrum do they produce?

Sorry if I wasn't clear, but I am installing 150watt HID floodlights. Both MH & HPS bulbs will fit.
...edited my 1st post.

By the way, how many plants do you think I should plant? Was thinking of putting 6 in there.
