CHIHIROS RGB 30
Testing video. PAR MEASURED IN WATER. Although this fixture is a little more expensive than your average budget fixture (Beamworks/Finnex), it makes up for it in quality and construction. The top of the fixture is subtle heatsink which help dissipate heat. It outputs higher PAR values than the Finnex FugeRay Planted+ and Beamworks DA FSPEC counterparts and is adjustable in length up to 18" (can extend even longer but light coverage suffers) and height up to 8.5 inches.
PAR tested using Seneye PAR meter unless otherwise noted in the notes section. Testing process is documented here
