Hi!

Ive been getting mixed input on this and i just wanted to the get your opinion, I am between this light

But i am afraid it might be too much for my tank and bleach the crap out of my coral... ( I have a 100 gallon tank) 48x24x18

Or this light...

the main difference between the two is the 1 watt vs. 3 watt

what do you guys this i should get? would the first one be too much?

I would get the 3 watt system. It is twice as wide so you will get better coverage in your tank. These Leds don't look like they have optics to diffuse the light and spread it throughout the tank.

Your dimensions sound like those of an 80 gal tank, diy led ftw.
