Doesn't noticeably add to the heat of tent at all, but its more than adequately vented. Put out a decent amount of heat which is more noticeable in my situation since the enclosure is on the smaller side. Pic is with mars hydro both at 100%.

Has a dimmer function - (though - see below) board has a decent glue (as in like conformal) coating to protect the solder joints on the smds from corrosion and moisture. The ppfd was perfect for my venus flytraps which require 400 to 500 ppfd.

This is something that some other brands in the same price and watts consumed do not have. It is reasonable in designing an appliance using leds to ensure the diodes will always be a bit *under-driven* not only for higher efficacy watt for watt.

This light is not worth buying flickering after a month of being on. The dimmer is horrible though. Getting it to stay straight depends on the power cable not pushing the fixture.
