Introducing CobKits.com - specializing in DIY and Citizen COBs

those things are beasts

however - please note that these are not covered by warranty (per HLG)

was news to me, i need to update the page.

Apparently (unlike the phosphor chips we are used to), if wired backwards, all the samsung reds blow out

so please be careful when wiring - no room for error

Yeah, now they won't sell it DIY anymore..... and when I have the money I need 2 more.........

Finally finished my first COB light build!
16X 50w Luminus CXM-22-HM
Just need to mount the 2 Solacure UVB tube and it be ready for next grow.

lookin good... gonna be a beast rig.

where did you source the lenses?

Even though I bought a bunch of the 648 boards before HLG said no warranties, something tells me that they would still help this old person out if I have any issues (after wiring them correctly and under normal use, of course). I think it's silly not to consult the HLG website and the people here to triple check before saying, "Hold on to your butts" and hitting the surge protector switch for the first time(I had to do it, for Samuel L. Jackson's glory).

It's pretty awesome you stock them man, they look mighty fine and my peppers are loving it! Thanks for the awesome service, shipped same day and got here in one piece.

Glad to see a representative active in a forum

Got them on alibaba.com with the heatsink, shipping is like half the order, costed me like 1200$ CAN for the 32 heatsink and 32 lens 120 degree.

just got triple and single slate heatsinks for the QBs back in stock

@CobKits

I'm wondering if this is an error, doesn't make sense to me on driver selection seems backwards to me

HLG480H-C2800 x3 QB648

Should be dimmed with this driver (???)

HLG480H-C2100 x4 QB648

I need some advice, do you think the 3.500" heatsink usa profile at 48" would be good for 5 1212's at 50w. ?

Get the 4.85 wide, it's actually cheaper than the 3.5 and has the disapation capacity you need. I built a light with a 40" slab of this running 6 Cree 2530 @ 40 watts each and it worked fine If I remember correctly heat at temp at the heatsink was 90F

Great i sent you a mail, do you accept bitcoin? Thanks.

yes i accept bitcoin, by arrangement.

we need to agree on a rate and I have to know when its coming so i can turn it into cash as soon as it transfers. Its too volatile and in the past i would have people buy stuff on one of bitcoins erratic pumps and lose 10% or more by the time i could cash it out

hi x3 Luminus CXM22 Gen4 3500K on HLG-185H-48A Driver

They would be fine or what is the best chip for this driver?
