I know this thread is a little older, but I use 2 of these exact lights in a 4'x2' tent and I love them, I'm on my 7th grow and have had no problems yet with them, I was expecting maybe 3-4 grows when I purchased them but they have hung in, long past my 3w or 5w fixtures ever did, I'm not saying they are GREAT by any means but they get the job done, and yes accurate draw at the wall for both fixtures running at the same time is 387w, so roughly 200w at the wall, honestly had better results with these lights and photoperiod plants I can clone, with autos I end up with a uneven canopy at times and shorter plants end up not as dense as taller plants and blah blah blah, but IMHO worth the $$ I paid for them, they can do the job and do it well
