It looks very smart, what will the mounting options be? Also will it have a lunar feature? What will the 4 colour channels be?
for mountings will try to provide different options - directly on bridges I usually provide, goose-neck and a hanging option; In my opinion bridges offers the highest flexibility and stability (will come with details at that step of development)
Lunar feature comes directly from controller, as leds can be dimmed really low (0.25-0.50%) which is low enough and doesnt need dedicated lunar channel
For the colors on each channel I will come with some proposals, but also customers can ask for custom LEDs to be placed in order to meet all tastes - combining on same board different footprints from different manufacturers possibilities are endless;
As starting point channel 1 will be actin (mix of 450 nm blue + UVs), Ch 2 - whites, Ch 3 - 450 nm blue again (honestly I really think 2 to 1 ratio of deep-blue / white is what reef tanks should use); Channel 4 is for color enhancing where can be mixed regular blue, cyan, lime, ultra-red, etc
