I have seen these in action at the LFS. Not sure I would recommend them...this light is very small, maybe only 8" across and would really only act as a spotlight on a 30" tank. Would be good for a refugium that required metal halide. Have you considered this one?

If this is not for you, I would consider trying to gind a single 250W or 400W pendant used - they are often at least 4-8 inches wider and would provide you much better coverage.
What are you planning for actinics if you go with a single pendant? Gotta love the actincs.

It's height is somewhat adjustable, clamps on easy and you can add more if you chose. i could buy 3 of these bad boys for the price of a 250w MH & PC canopy by Hamilton or PFO.
One more question remains though.. Is the intensity and effectiveness of multiple lamps be different (better/not better) than one big lamp? |
