Prices on cobs are much cheaper now for cobs of equivalent output and efficiency.
12 cobs $400 roughly
heatsinks $50
Wires and $30
Kapton tape $6
Thermal paste $8
Led drivers (on sale) $50 for one $65 for the other.
Dimmer rheostat (can use just one to multiple drivers/lights) 10 for $10 I tbink

$600+ and there are other parts I am forgetting likely that are cheap
That's about the price of a nice ballast and sealed hood so that's not bad at all seing cobs last way longer.

Im not an electrician, but I like you fix my appliances when I can.
you should have no problem building a nice light.
Mine is rough looking, but I got 1.25 gpw with it in organic soil so like 3x better than I did with HID, but also scrogged and never did that with HID so not completely fair comparison
You guys just set me on a new thought process. Fuck those cmh lights hanging vertical which I need to have sent here anyway. I'll piece together what I need to build my own cobs, thats easier to ship here anyway.
@ttystikk I didnt look too hard but that company out of Aus offers a complete build kit in pieces don't they?

You should take one of your heavy shade producing strains and put it out on the farm in full sun to see what happens?
great minds think alike...I grew wonder woman under my shadecloth and 3 hours less sun than a plant out in open daily and yielded around 27 oz of nice dense buds with a few oz of popcorn...then last year I took a wonder woman seed from the same pack and grew one out my mates farm full sun similar soil and ferts and that one yielded a massive nearly 3.5 lbs with near on hardly anything we would call popcorn in aust....wonder woman is a huge yielder given the right conditions or even in my case gd conditions but not quite 100% sun

theres a dude on thc farmer that does a killer home made set up up @Vnsmkr ..id post the link but only if u want it cobs with and without led I think
Yeah lets see it, why not. Though also the reason for me building is I wont have to have a complete setup shipped in here. Ive done electronic/electrical tech duties soldering and the bunch at my old job so no issues there

I really miss my old wardrobe I only had a 400 wt hps in there but used to pull 8-12 oz off one plant homemade set up...not bad for a 18yr old when weed was 280-300 for nl strains back then...in a galaxy faaar away

You can get parts from Australia or from China, whatever is cheaper. If you're referring to @welight I'm not sure, but I think they do offer kits.

CMH are nice lights from what I have seen, but I must think cobs are so much nier with different spectrum's and CRIs and they can be dimmed, not to mention scale able to any size grow and getting more efficient all the time, but were more efficient than any HID already a few yrs ago
