So I just wanted to update. I have now received my area 51 panel as well as my lumigrow 650, and I am impressed with both units. Just a couple things on both: Area 51- seems to be a nicely built panel. Very quiet, seems to put off a tiny bit more heat than I was expecting, certainly not bad at all though. Very pleasant light to work under, just put a Purple Wreck under it to flower, will let you know how it does... Lumigrow 650- this thing is freakin bright! Not the most pleasant light, especially when turned all the way up, its almost disorienting... I do like that it has the white only switch, but by the time I open the tent and hit the switch, everything already looks weird. Definitely a very solid feeling unit, and I was relieved that coverage isn't an issue in a 4x4. Am replacing a 600w rig in there, we'll see how they compare. No journals, but I may post some pics from time to time...
