Chief,
I borrowed this from another site, but it pretty much states a good point:
"We all came from MHs or fluorescents. Early on, we were totally unprepared for the switch to LEDs. The fact that LEDs don't appear as bright to the human eye as MH/T5, coupled with the lack of radiant energy (they don't "feel" hot) add in the lesser electrical demand generating almost ideal PAR output, the efficiency of the optics utilized, further compounded by the lack of PAR meters...all combine to create a perfect scenario for the destruction of a lot of livestock... Early on almost everyone blasted their tank with far too much PAR - We just didn't understand how powerful these tiny emitters were."
This was taken from another website and written by someone else, however it puts into perspective the LED craze. please note this is reference to the AI module which has only 24 leds, yet has more par than some MH.
I posted this to inform, that its not about the brightness but rather the par and the capability of the unit to perform its function. BTW I give this opinion as someone who owns a unit which is on a marineland 45 gallon cube.
