    So 4 of them lined up near each other might reach 1000.

    Probably, what kind of par are you looking for with an algae scrubber? I never measured the PAR coming from the 100watt CFL I was using before this.

    I cleaned my screen yesterday so I should have some good growth progression photos showing up using just the LED. My previous ones were started with the CFL and swapped to LED midway between cleaning cycle.

    No number. Higher nutrients need stronger light.

    Should I start a new thread for my scrubber, or post on this one. Is MFK website ok?

    The suction cup, thumb screw thread length. Fits, a little loose on 2 of the 8, if the bolt threads were a 1/8" shorter. They would tighten up on the thinner LED frame moldings. A slightly thicker, LED, molded frame part. Will fix it also.
    Spent 5 minutes to install new lights in my sump. I LIKE the plugs for easy routing.
