A Finnex Ray2 DS would be pretty good for your tank. They get good spread, too. One at first then you could always add another if you feel like you need more light. Alternatively, you could get a two or four bulb T5HO setup from a good company and adjust the bulbs/fixture height as needed.
While I've read of Odyssea fires with their metal halides years ago I've never heard of such problems with their t5ho fixtures. In any case the Ray2 is still the best choice nowadays, a year ago the Odyssea would have been the most economical option.
I can tell you from personal experience that the money you save when buying the Odyssea light is not worth it, and it won't take long to find out. I was lucky, mine just burned the bulb and melted some of the plastic and nothing more came of it. Maybe there was a ball of flame like some claim to have, but I wasn't there to see it. Save your money, and buy something worth while. PS the LED is also not worth your while.
Had a Current USA fixture fry while 3 others have provided years of great service.
Only posting because of the comments above on Odyssea fixtures.
I have 2 that are more than a year in service without any issues.

I am running LEDs on low-tech tanks. I will never go back to flourescents. I have heard good things about the Ray fixtures, and I have personally used the marineland double-bright and planted-tank fixtures.
