It's just like any other chip that I've played with. It needs a heat sink. No I didn't buy any reflectors. I like the cobs without refkectors. Coverage is better. Here's one I built using lenses but I took the lenses off.
This is heart breaking. One day I'll do everything in my power to make sure seeds of all kinds are free. People shouldn't have to pay for genetics imo.
Okay so I've avoided this thread like the plague for years. I'm working on my second child moving out so I think I qualify now lol. So...what's up old people? I assume terms like lit and on fleek aren't allowed haha.
Here's a lil light I threw together using a cheap Chinese 20w cob with an integrated driver. Just soldered a 110v ac plug to it, mounted it to a heat sink and it's done. Pulling a lil over 12w from the wall.
Thank you very much rose! That lil one is in a pot with a revegged plant that was seeded. I guess it dropped a seed so I just left it. It's more than likely a Deep Chunk seedling but who knows?
Right now on cobkits.com you can buy the citizen clu048 chips for $9-11 each. They're regularly $20+ and kind of fun to play with themselves. I'm going to build another just as soon as my other components arrive.
Here's my latest screwdriver. I'm using 2 citezen clu048 cob chips, 1 4000k and 1 3500k. Theyre being driven at 600ma and pulling a lil under 45w from the wall, 44.2w to be exact. They're so bright I can't believe I wasted so much time with the lil 3w chips.
