7 royal blue 3 white and 2 royal blue moonlights not pictured blew 3 LEDs on accident :-( so it's on hold till I order 3 new LEDs first first time soldering also and did a
Pretty good job so far for now itll go
In the hood of my nano but I will be hanging it later on.
Still thinking about it I think that while in the hood it won't need them but once I hang I think it'll be a good idea. 40 degree lenses was what I was thinking to keep it more directly on the tank rather then all spread
Optics once you hang it for sure, in the hood the spread will be fine. Good luck, it looks like a pretty nice build so far. We love the DIY led I built for our 29g BioCube. Makes it feel like a whole different tank.
