Nice thread guys
I don't get around these parts often but have found my way back here researching COB lighting
I recently embarked down this road myself, working with Kingbrite, and will have in a day or two 12 x CXB3590 CD 3500K, will run them at 1400mA (3 x HLG185-C1400A), all passive cooled pin sinks, for a total of 615w or something once you factor in driver losses. All in delivered from China to Europe with shipping inside a week (TNT), this will cost about 850 USD total, if that gives you some idea on the price @mandalaman, mount them on rail is maybe another fifty bucks max depending on where you live and what tools you already have laying around the house, if you have to buy killawatt or soldering irons etc it's gonna be more the first time you build one obviously
I'm really excited about it, have been eyeing COB for a long time. I'm a HPS guy currently, with little electronics experience beyond that of most growers I suppose. But yeah COB wiring in series is so simple that an eight year old could do it safely
I'll let you know how it goes fellas; I'm getting ahead of myself
Thanks to all those that keep propelling the COB tech forward, apart from the high start up cost it seems fairly unbeatable in every aspect by any other light tech that exists to be honest in a watt by watt comparison of PPFD etc. I was stubborn two years ago when i first saw it, but I saw the light eventually, no pun intended
If it goes well I will replace all my HPS with it probably. But the proof is in the pudding, and the front end costs are nothing to be sniffed at, even if you grow weed
