iam at work now so bare with me ohhh i am bored out of my mind
well i have been waiting for deals from suppliers and trying to figure what power supply to go with.
now that its all done.
everything i ordered is on the way max waiting time is 10 days cannot wait in the mean time i have few cree led that i have been playing with.
the dimentions for my heat sink will be 7.5" wide by 26" long for starters i will be placing 40 royal blue at 575mW@1A and 20 cool white 6500K 220lm at 1A
i like the deep ocean colour as it will be at that for the sunrise and sunset.
yes i could setup to give me the proper balance that suites me and of course the corals.thats done by a potentiometer variation from 350MA to 1000MA brightness for every series of coloures or individual colour of LED.
without the lense on the led my tank will be able to sustain life of sps lps and softies even at the base given that the depth of my tank is 20"
to reach deeper you could always place lenses over your LED that ranges fron 22degree angle to 60degree angle.
mine is at 120degree angle.
i hope i answered most of your question.of course i will be detailing all this with photos and videos later.
YES its expensive but i am sure it will pay of at the end.
cheers
