I am creating a custom box that will contain 3 * 400 watt metal halide bulbs (1200 watt total). The box will remain closed for 60 minutes, open for the next 60 minutes, then closed, then open and so on.. for a period of 10 hours. The box will open/close from the the front panel (the "door") using Arduino and Servo motors.
Since the bulbs will be generating a lot of heat I will attach a Duct Fan at 240 CFM on top of the box (is the top the best place to put it?). Something like this: http://www.amazon.com/dp/B005KMTYFK/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=V2E1GXE4DR4J&coliid=I3B1JSME5M15UN
The box itself will be made out of wood so I will coat it with a heat resistant spray from the inside so it doesn't catch on fire. Something like this: http://www.amazon.com/dp/B000CPJLV2/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=V2E1GXE4DR4J&coliid=I122VPINWI1GBY&psc=1
When the box is open I will need the box to emit as much light as possible. Therefore, I will coat the inside with a reflective substance (something like this: http://www.amazon.com/Rust-Oleum-1915830-Metallic-Silver-11-Ounce/dp/B000PQGE2M/ref=pd_sim_hi_3?ie=UTF8&refRID=0DKBGQGVVCT0YSWCW1WB) so all light rays are dispersed from the box..
What do you think?
Thanks
