a thought just occurred to me coming home from a 12 hour shift i saw the mh parking lot lights on the way to my apartment,
could these lights be used for a tank ?
i just checked hd and they are a 70 watt unit.
there are also 400 watt units too.
and they are sealed behind a tempered lens cover.
they look like they could work.
any comments?

what about the high pressure sodium lamps.
i dont know aout them too much .
they look like they will put out too much light in the red section of the light spectrum.

just curious :)
 
The spectrum of light emitted from these commercial lamps are too low. You would have a very yellow light which could encourage algae growth.

Not sure about HPS. I don't think I have ever seen a tank running one of these bulbs. For High Intensity Discharge, its mostly Metal Halide or Mercury Vapor.
