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.
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.
