We've got a couple of the Hydrofarm 400W and another from Sunlight Supply.
The Hydrofarm lights are big. They are set up to handle ducting to air-cool
the lights, but I've never quite gotten around to trying that feature yet.
The one from Sunlight is about half the size, and seems to do just as well.
The industrial looking types weren't an option for me when we bought them
for aesthetic reasons (we were short on space, had one in the living room
and two in a bedroom). As far as new/refurb/used, whatever you're
comfortable with.

My basement indoor space is 5X4, and I recently added a shelf (3 tiers)
with 2 double florescents above each shelf. I want to add a 400 watt MH,
hung from the ceiling to add more light (and grow some other taller
plants- like Hibiscus). I figure that the lower light orchids can be on
the lower shelves, with the high-light lovers on the upper shelves
closer to the MH.
My question is about the MH light itself. I have been searching ebay,
and the web. What should I buy? There are many different types:
Industrial hi-bay types
Grow lights like Hydrofarm
Cheaper Grow Lights w/ batwing reflectors
Flood light fixtures
Etc.

They can be bought used, refurbed, or new. And there is a huge price
difference amoung the different types. Obviously those Hydrofarms are
the best, but is it worth the extra money?

If anyone can recommend a type of light, or share experiences I would
greatly appreciate it!
