Very good for the price. Decent build quality. Colours good, plenty of range due to the added amber, white and UV. LEDs don?t seem much brighter than the ADJ 3W equivalents, but 12W is the power draw, not a measure of output so it?s just a rough guide. No matter, they?re still nice and bright. I plan to mount these on the FOH speaker stacks aiming sideways across the front of the band to light the singer?s face as best possible - you can?t easily mount lights out front of a pub band. A mix of white and amber should give a warm enough white, wth maybe a little UV to make our white shirts ?pop?, adding to our stage presence. DMX control is good, would have quite liked ability to set different colours on each LED, but not a big issue. Included infra red remote works well, conveniently it can still be used to override DMX without having to change mode on the back panel. That?ll be handy between sets when people want to use the stage mics to make announcements, speeches etc without having to activate the rest of the lights (I?m using a pre-programmed DMX dongle to drive the light ?show? while I play bass). I?m very pleased with these lights, they compare well with the ADJ lights in our rig.
