If you look at the first picture (showing the puck side of one standing on end) you can see the reflection of the splash guard that is on the light. If your tank is 42" deep then I would get the TIR lens for the pucks to focus the light a bit. My tank is only 24" deep but it's a ton of light at that depth. I'm sure I could grow SPS on the sand bed with these lights. My pucks are not the Pro just the G3. I will not be adding the extra LED's (I can always add individual colors to the heat sync if I want to increase the colors in the spectrum (I see no need to do that so far). Good luck with your build! Krazie:jester:
