If the 94x3w is the green 2 panel one with the growth and bloom buttons on it then I'm pretty pleased with it after 2 weeks.
Scored one for cheap on a popular auction site and it's outshining my 250w cfl by a long way (even considering it's a 300w). No noticeable stretching that I got with the cfls (long due new bulbs to be fair to it).
In a grow space maybe 60w/60d/200h it's the only light, heat seems to be a non issue..you can rest your hand on top of the unit or hold it right near the leds with very little heat. There's a slight hum from 2 fans in it but they're so quiet my ruck fan/filter and regular fan drowns them out easily.
Only possible negative I'd mention is you can't just have the bloom turned on, the growth needs to be on for the fans to work..not sure if bloom alone makes enough heat to damage anything internal. Haven't taken the risk personally, I'm happy with growth and bloom on so far.
