Recently built and have been extremely happy with my new Citizen LED COB setup. Dual Citizen CLU058-3618C4's running off an HLG-320H-C2800B in a parallel configuration. As I understand this is running @ 320W split between 2x COB's for 160w ea
X2 Love them! The dual COB's @ 320 w do a damn fine job of covering a 3x6 flood table. I haven't flowered anything with this setup, but they do an amazing job vegging things with a perfect 4000k spectrum.

Dude, those are bitchin' COBs!

21,000 lumens each at 1,400mA... Nice. Where did you get the heat sinks?

They are from led-heatsink.com IceLED active coolers. Need to purchase a 12vdc 1amp driver to spin them too.

What?!? A single COB putting out 21000 lm? How many watts to get there? How much light:heat?

320w / 2 COBS. They have a max rating of 524w however. Very little heat. Once after a power outage the Driver for the heatsink fans didn't restart. I touched the heatsink and it hurt/was too hot to touch. But the COB was still shining away seemingly unaffected. Wouldn't want to leave it like that for 12+ hours, but it was just fine!

I like the slotted rails. It's like Meccano for adults.

"Angle Iron" DIY hardware store special

Yeah, it was the thermal interface material. A big glob of Arctic Silver later and everything's groovy. 480w's of 4000k fury!

Hahaha that's like the frickin spotlight from the 20th Century Fox intro. Glad everything is working - that's a beauty!
