nice clean set up.
any close up pictures of how you mounted the led heat sink to the pfo pendant, does the mh heat up the leds? also, how do you like the 10 rb, 2 blue? i was thinking of doing 8 rb, 4 uv or 12 rb, 6 uv on a dimmer.
i want to do the same thing (even using rapidled actinic kit) but with a lumenbrite instead of a pfo pendant, though same bulb and pfo ballast. i have a smaller 38 gallon cube.
thx
there you go, i just uploaded a pic i took with my phone. i measured the distance between the fins to find a bolt/nut combo that was short enough. I measured and then drilled holes into both the pendant and the heatsinks. If I had a drill press, I would have used that.
The MH does heat up the heatsinks unfortunately, but I've had no problems so far. It is hot to the touch, but the leds themselves can take a beating.
You're correct: I have 10 RB and 2 Blues. I wanted to add UVs, but they were sold out. When I installed these, they gave the color response I was hoping for so I stayed with it.
If I could change things, I would definitely go with a bigger reflector like you are thinking of doing. Especially since my tank is a cube and it would fit the dimensions perfectly.
