Keef, if your considering those spider farmer lights...one thing is the sf-2000 is not the same as two sf-1000, the 2000 has more than double the number of LED’s and perhaps some different mixing of red in there...they seem to used quality components in the leds and drivers...mine had a screw loose that would not thread back into the hole...I didn’t force it because I may move the driver out of the grow box anyway...right now I need the heat inside...there really isn’t much to them, just a stamped out flat piece of aluminum....with hangers of course...wish I had a space to hang ona those big mutha’s...
