Building upon the success of the original COB Cannon Wash, the shorter American DJ COB Cannon Wash ST DW is an LED Par fixture that uses cool-white and warm-white COB (Chip On Board) technology, well suited for mobile or permanent wash lighting of stages, clubs, dance floors, or places of worship. The fixture produces high output and smooth washes without shadows. It ships with a standard 80° beam angle lens, but can be easily changed via the included 40° and 50° lenses.
