i have heard the reef brights run cool. i am not worried about changing bulbs every 12-18 months.
i am looking at spending $100 for each reef bright setups plus a 4 new aquabright 14k bulbs at $65 each.
so all in, call it $200 per fixture with shipping. I have 3 g4 xr30 pros to sell, so that offsets the initial purchase. i would have to ad at least 1 if not 2 more g4 xr30s i would think. cost for 2 used g4s will run me bulbs for 2-3 years.
my house is old and drafty, originally built in 1759. extra heat in the winter is no big deal, and summer fans to keep the tank temp down and a big ATO. The added electricity bill will suck but i am going from a 125 to a 300. The bill will go up, that's inevitable.
would like to find more info on these reefbright fixtures and people using them.
