Id have to believe there are people out there, paying attention to what has been going on, in the underground...What fellas like us are putting together, and the results that have been realized....

This is NOT the same browsing experience as with either of those brands.
This is a company (in China, where everything's fuckin made) that builds a fixture along with probably a few others, but also creates, layer, print traces, screen solder, pick and place LEDs, and reflows them to the boards with an oven. They MAKE their own PCBs and sell them individually or as kits as well.
There are Several reputable Chinese Alibaba/Aliexpress vendors that many of us have had great experiences with and whose products are still working today. Basically as bright as the first day you plugged it in.

It is awesome that you find the reliable supplier at first. I really had a bad experience with a chinese supplier. Good luck!

Who's gonna be the guinea pig and crank that passive bar fixture to 800w for a couple of months and see what happens?

I'd take a guess, but that means shit.....

@dalack buy either the first one you posted or look into and contact the supplier I linked for the other fixture and see if that's a better deal for what they offer. If you really can get meanwells rather than the Nalite drivers, you'd be doing yourself a huge favor.

so is it even worth it anymore to continue my slow upgrade to COBS or do i just need to stop and throw down on something like this or qbs and use my current cobs (10 cxb 3590s) for vegging? lol

CXB3590's are still just as good as anything. Not as efficient, but definitely not something to feel like it needs to be upgraded. Even if your lights were on 24/7 for the last 2 yrs, you're still around 95% as bright as the day you turned em on.

well I have been trying to slowly upgrade a 5 x 5 using either 20 or 25 cobs but it seems like they are not as easy to find anymore... everyone is on qbs or veros etc... I have thought about just biting the bullet and going the alibaba route... but I am so unsure of what I will get with the kits available

COBS are hard to find? Where you live?

Arrow, Digikey, mouser, rapidled, cobkits and several others ALL sell Crees,Vero's, and Citizens...

I guess I just have to stop being lazy and do some ACTUAL DIY instead of just wiring together some pre built cobs on heat sinks etc lol thanks for the heads up

Shit is cake man. Harbor freight sells a top notch SAE/metric tap and die set for $39 you can return after you use the one tap you'll need, that will allow you to tap anything you may need to. Aluminum soft AF but it never hurts to add a bit of lube to the hole when you do it. Even just clean motor oil works great.

Any tips on which of those sites is easier to order from? I see the kits on alibaba that just have everything included ie cobs holders heat sinks all that. Is that legit or would you advise just gathering up all the materials myself individually? I dont mind buying tools at all and I'm sure I will use them again at some point.

Kits from China for older CObs you can pretty much guarantee will be legit. Whether it's Vero's,Cree or citizen.
