Well, time for another quick update on the lights.
Got them all hooked up to my new APEX tonight. Ran through some programs and then put them all on at once. Note that this is a picture through the plastic film protecting the plexi...which I believe is cutting the light by 30-40%. Most of the lights are on at about 75% here.
I have to say, it's pretty cool seeing the APEX put this through it's paces. The fixture is really quiet and you won't hear it inside the canopy at all. The fans are doing okay but right now, I'm a little concerned about heat at the two ends which are farthest from the fans. I will take my heat gun to read the temperatures after I get everything to 100% for an hour and see if it's within the LED specs.
