I have 16 Par 64 plug and play stage cans mounted on a four foot 1" aluminum square tubing.
Each tubing has 4 cans mounted with a ADJ DP-DMX 20L dimmer pack. The tubing can be attached to a standard T-bar via the 2 ADJ "O" clamps bolted on the tubing.
8 of the cans are 600w sealed beam bulbs and the other 8 are 600w DYS elements, all with gel frames.
I also have some spare bulbs
$125 for all
