This is the later WW/CW/A version of the unit. Despite some of the descriptions the unit has both powercon in and out sockets with DMX on 3 pin XLR.
I cannot hear a fan, so presume there isn't one. There is a minor whine of the electronics, but this should not be an issue unless you are using many of these units.
Light wise, it's possible to mix a good tungsten colour. Output of the CW is not as powerful to the eye as the WW/A colours. I would recommend some diffusion gel to take the glare down and soften a little to the eyes. The unit gives a wide wash of light, so should be good in close proximity.
The metalwork is strong and the bracket tough - not like cheap LED pars.
Minor gripe is that both units I've had I feel the packaging of the unit was slightly inadequate as the brackets for the bard door holders have come bent, and the doors themselves slightly scratched and bent having rubbed against the unit in transit. Perhaps the accessories (included are both barn doors and gel frame) should be in a separate box. No big deal, but annoying for a shiny new unit.
