Kessil for new tank build info ???

[hfp75]

I'm a kessil fan. I'm using 2x 360we over my 48x20x20 and had the intensity at 85 - things weren't happy and I've just pulled the 2x down to 70 - i think 70 or 75 will be my sweet spot..... Maybe even 65.

I want to use 3x for the added light source and will just decrease the intensity to 55 or 60.....

Just remember that LEDs are directional light - regardless of the angle of the lens below the diode.
