Whiskey sent me his when I had my 'dinosaur-lights'....the t12's and the t8's crammed into my hood covered in foil. Was curious about the output over my tank, plus I had a whole wall of windows to offset them. I have since went out and bought one like his......wanted it for when I got my new t5s, so I didn't burn all my Corals up. 😁
They did the trick for keeping my softies, but think my PAR from just my lights at the top of the reef was struggling to hit 100......and at the bottom may have been around 45 PAR.
The t5's spoiled me....(2) 8-bulb 4' fixtures.....YEAH, that was a PAR MACHINE!
Though these new LEDs would make them cry in envy!
