100 leds? Holy crap. I just priced out 40 and think I'll start with that. Can always add if I have to. Not sure how I'll arrange them or how many to a plug, but I'll figure that out.
I'm running 6 (3 white and 3 blue) in one plug now.
One of the problems with these LEDs is that the lenses create blue and white spotlights. I ended up removing the optics to create more blended color. I'm not sure removing optics is a good idea for bigger tanks like yours because par reading is horrible without optics.

Very true......Do you know how many 4x1's you can put on a single run?If I did 30 total to start would it be ok to do 15 whites on one plug and 15 blues on the other?
So it seems as though wood would work just fine. I googled pictures and it looks as though you just use small screws in through where the leds screw into and screw them directly into wood? Sound about right?
