Yeah man, I got a heatsink that was in a 320 kit, fins were bent on one corner. Not to bad, paint was chipped off though. I straightened it up with some channel locks. It’s fine now.
I got two kits from GrowersLights at that time. One board out of the three in each kit, has diodes that go dim as the wattage is turned down until they go completely out. Five or six on each board. Both of these kits came from GrowersLights. I didn’t notice the diode thing until I’d been running’em for about six months. Up on bright, you wouldn’t notice it. But I suspect it was that way from the get go. It’s not a big problem, and I’m still ok. But it kinda didn’t seem right. Especially the heatsink. The box it came in wasn’t torn anywhere. I was surprised someone didn’t see it being bent before I did. I’m thinking it was that way when it was packaged and then shipped. Quality control was definitely slacking. I’m pretty sure it was noticeable before I got it. And the two faulty boards. Same thing, somethings not right. But after six months I’m thinking it’s to late. No sales receipt, I don’t know where it’s at. But I’ll keep my paperwork from now on! Lol.
I purchased three more hlg- 320 kits a couple weeks after those first two. Got these three straight from HLG. They’re perfect! No problem whatsoever. I want to make sure everyone understands that I love my lights. I’m serious, i love’em. I’m in the process now of purchasing heatsinks and boards for diy projects. But I think I’m going through HLG to get what I need whenever possible. LED, it’s the way. I’m now on my fourth run with’em.
