Took some light reading at max intensity with the ATI fixture.
@12" from the water's surface: 500 umol.
Middle along the sediment: 180-190umol
Bottom corners/front, 140-150umol.
Butt load of light.
I'm removing a purple and adding another white colored bulbs and removing thh Aquaflora in the rear and going with an Aquawave red.
Fish color is 10X better.
I think I figured out how specifically ATI gets some of the increase in lighting, the reflectors are specific and do not cause spill over into the room nearly as much as the Tek.
It's a huge improvement to the living area!
LED's do this same thing when designed correctly.
I estimated I'd get 175 umol or so, and that is just about right.
I got 120 umol or about 45% increased vs Tek at the same distances.
Now........I can use this increase various ways with the ATI..........I can dial down the % on the dimmer, or I can add a midday spike(or several small spikes) and/or shorter the photoperiod. I have many options.
The fixture does not look nearly as bright, but......... the light meter does not lie.
