I ordered a set of the ratcheting pulleys and I hope that with that and maybe some PVC, I can rig up a cross member that I can use to raise and lower my LED.. I got mine in today and it's pretty sick!!! I haven't plugged it in, but just feeling the weight and the construction, it feels like a very high end piece of equipment!!
You could always rig up your own pulley system to raise and lower the lights..... Or..... You could mount them at 45deg angles vectoring down towards the center of the plant on opposite sides of the tent, and then perhaps take your 3rd one and mount it right in the middle of the top.. Lots and lots of coverage!!
