Introducing CobKits.com - specializing in DIY and Citizen COBs

would it make sense? whats your budget? yes it will be more efficient but your cost for the rig goes up a bit and it takes a while to recover it

if you buy the 30 packs at a discount on the site thats alot of bang for the buck esp doubling up on heatsinks

Can the gen 5 and gen 6 1212 chips be run together on the same controller?

not advisable in parallel due to different Fv. with a bunch of cobs (12+) not that big of a deal but you might see 10% difference in flux from cob to cob.. if you were gonna do that do a checkerboard style pattern of mixing em up for uniform light to canopy
 
hey cobkits.

ok, so ive decided to just use 4 Luminus cxb22's, with the 600H-54B. in a 2x2 tent.

I want to run them at 55 watts each to 85ish for flower.
So only using 220 watts,
What are the drawbacks from this setup please.

should probably add, I will be using a Zigbee wifi controller. It allows me to sunrise/sunset simulation. So actually, the watts will be very very low early in the day and late in the day.

i paid $120 for the driver, a 320H is $140 alone, plus, i can crank it up to 400 watts if i want, and cant with, " just enough"..

ok, just making sure. Im ordering next week for the lights and heat sinks and such from u, so again, thanks man for your help.
 
Hey Cobkits. OK< decided to go with 2x185H-1400B for the 4 Luminus cxm22..

LOL< After crunching measurements, I cant fit a 600H into my build box. Plus, it will be much easier to hook up, because I think with the 600H, Id have to hook up fuses per light to resist the max input per cob. So would of put in 2amp fuses if i ran that route.
But anyways, this will be much better, like you said before.

wouldnt have enough room, because Im also putting in 2 fans to suck the heat from the COBs, up thru my build, so need another 12-12 driver for those, needed one anyways to run my GrowMau night puck.

Then need a Sonoff for the Puck, while using the zigbee for the lights. The fans sucking the air from the cobs will be ran 24/7.

I have alot to fit into kinda small area.

What size wire you recommend for all the wiring?

Just trying to have the most correct plan inplace before ordering wrong sht.
 
@CobKits im a total noob in diy ( friend did my 4x cree 3590) , i have this in double from my previous time i tried to make one (wrong drivers and 2 cxb 3590 that i wasn't needed... not your well prepared type of guy..)

I wanted to know if this driver is enough for a single qb280?

Can i use the 2 cxb with this driver??

Also looking at the cmx22 passive light engine on your site, can i use 4 of them with a hlg 186h-c1400b? If not wich driver should i use?? Thanks
