I have yours. Pulled it apart. Can't find any obvious problems. I'm guessing it's the driver going thermal. I even cleaned out all the dust bunnies. Cooling fan works. I think you should send it in to them. I have ur red one too still BTW.Kessil is having a sale too so they were a great price. Snagged me a couple of H380s and an H150 Blue. I am thinking about getting the wide angle 15K or 10K blue also.
Don't eff around with root aphids. they will dud out your plants. Use triazicide (Spectracide) at 10ml per gallon and drench. Imidacloprid works well too (Bayer complete) I would drench 3 times once every 4 days.OK - this has got to be the most ridiculous thing ever - I put up a no-pest strip in my clone cab to make it a no bug zone. Worked great on the mites! Unfortunately it seems to make root aphids go nuts! Now I need to figure out how to kill the root aphids. FML!!!
We can put some clones of those in my greenhouse early spring (feb) and let them rock and roll.
