    DUET 2400 (LED FIXTURE) - UP TO 2400 WATTS (Flip Chip Opto)

    We use a cold forging fin patent from our sister company, it weights 60 pounds inclusive of everything including the power supplies. That tripod stand you see, can be used as a stand, but it's actually an adjustable bracket (90/180 or 270 I can't remember) for you to hand it on ceilings.

    Hi SupraSPL, Your explanation is relatively correct, although our datasheets could be much more clearer. Everyone seems to be interested in our Tj and Tc.
