Got the light. Very bright and it runs cooler than I expected. I can lay my hand on the heat sink and the drivers and leave it there indefinitely. Bad news? Corner cables but no ratchet hanger and no instructions which means I have no idea how to dim the thing, Two holes with plugs, one marked Vo ADJ and the other Io ADJ. Anyone have any advice?
I'd get in touch with them and see what they say about dimming. Alternatively you can look up the driver and might find instructions that way.
