thanks for the kind words. re: nova, it's cheap and it works. for long term use i would not recommend buying it. the fan is noisy and they are not that bright. also the wiring seems a bit ify. if the fixture is slightly uneven 2 of the bulbs will not fire...it's odd. i needed something quick and cheap for the time being. with that in mind it's done it's job well.
if you keep your water very clean and low nutrient sps will grow no problem and with good colors, but there are others who have had a difficult time with the light, or lack there of. if you want to use it long term i'd look into ready retrofits or tek.
i am not sure how far the legs can reach, my guess would be ~26in.
