I have 130 watts over my 29 gallon, and soon I will replace it with an led fixture (if I eventually finally finish the fixture for my 10 gallon). I thought I was getting more light, but one bulb with a good reflector will be much better than two bulbs with inadequate reflectors and really cramped bulbs. If you do decide to go the odyssea route, definitely go the t5ho route. I think 4 bulb fixtures (I think 96 or so watts for 24" and 130 or something for 30") go for $60-90

Also, most 20L and 29 gallon tanks use 24" fixtures and 21" bulbs, although I'm not sure if there are any cons to having a 30 incher besides more light spilling out the sides.
Thanks for your comments Danny. Aquatraders doesn't make a 30" T5HO. Only 24 and 36. Would there be another brand you would recommend that is reasonably priced?

This unit is reasonably priced but I am afraid it is not enough light for my tank...

Current USA 30" Nova Extreme T-5 Fixture 2x24W 10K/Freshwater

This one is a bit more but under $200...

And let me ask about one more. Not the most expensive but certainly more and on the high end of what I would want to spend.

OK, let me ask my light question a different way. Would 48w of T5HO light be considered lowlight or higher for my 36G bowfront? (It is about 21" high.)

Then same question for double that (96w).

And one more question - These fixtures have 24" bulbs and my tank is 30" long - any reason to be concerned about that? Will plants not grow as well in the corners? (I am planning to fully plant both corners.)

Thanks!

38w would be low-mid light. 96w would be just on the brink of high-light territory.

I think you should be fine, as light expands and 3" on either side isn't too much.
