These leds without optics use are 120 Degrees this allows a more even spread of light and gives you more then enough PAR for corals even at the bottom of the tank. I have a Monti that has grown from 3" to over 6" in the last 4 months and it sits on a rock on at the bottom of my 75g. for a standard 125 he has no need for optics and infact I would say to avoid them.
There are few things that I know very well in this hobby and its Bare bottom tanks and LED
I love LED
's and think they are one of the best things that has happened in this hobby in a long time. Every tank in the hobby should be running LED
