I built mine probably in the same time frame. Most likely had $1k into my 3 heat sinks but have probably made that back in replacement halide or t5 bulbs. I enjoy the simplicity and compactness of the jardurino program and the ldd drivers. My original setup had nondimmable meanwell drivers which were a power supply nightmare plugging them all in and turning them on and off with my apex. I have a current heat sink with 48 leds and 4 nondimmable drivers that is over my small frag tank that would be fun to play with. Im getting amazing color out of my corals under that light but really dont remember what color of leds are on it.
thanks
