ok so heres my scenario.... i have a 180g tank that im currently running 2 250 phoenix 14k bulbs on.. im getting good growth but the shade areas are starting to bug me. so i could buy another pendant for about $350 plus 3 bulbs.....or i could build some diy leds, the problem is i have no clue about leds or how to build them, so all advice is welcome. i have looked at rapid led and looks like this could be a really cheap way to go. by the way these would be hanging, no canopy. thanx
