Not sure, there are multiple manufactures. The ones I imported used a little cheap controller box and were computer programmable. The Tautronics unit I tested was almost identical in PAR and even design to the ones I use. I think these have a small knob that dims the white side and another one for the blue side. As long as the wattage lines up and the lenses are right for the coverage you want, they will probably be okay.
On a side note, I am finding that even with Acros, we are using too much LED
light. I finally bought a PAR meter and my findings will be published this weekend, but I was surprised.
