what do you guys think? I saw BK use some alibaba lights and seeing how great his plants were I thought kingbrite strips would be a steal as well. Any thoughts on the light and the space its going to cover?

The light looks great at bargain price, kingbrite is by far my favourite led it's a cut above the meijiu I have.

I've a 5x5 I calculated 40/50w psf = 1000/1250w

Pretty low diode count on said light, you’ll have to run it pretty close to the canopy at full blast to get good coverage and penetration imo.

Also that light will struggle in a 4x4 for full coverage

Lemme know how it goes.

Its because the Meijiu you have is 4 year old stock you bought off a re seller on eBay. Basically their first ever boards and heatsinks.

Lm301H 4 years old, yes?

Eta Lol lm301h released in 2020

Agree on the diode count, these strips get driven a little harder than a standard qb: 120w thru 256 diodes versus 120w thru 288. But good thing is that you can always buy more strips, they sell those as singles/doubles aswell. I'd set it up and check how much the sink heats up, if it's more than 50C get some more strips and spread the watts out. It will make them last longer.
I'd still rather have something like this than the standard 480 kits with just a 2x2 Alu sheet, even if it was a hlg. Those have really bad spread and make tent growing a pain.

100% yes. I was just pointing out it’s a pretty low diode count is all. I never knew extra strips could be added to this light? If that’s the case I would definitely add at least 2 more to that frame.

I spend too much time hovering over alibubbers, waiting for one, just one seller to sell what I want: white + separate channel monoleds on a decent platform...

But yeah, those strips are 2 foot original and they will sell them as singles, doubles/4footers and kits. Adding more would require some small modifications but nothing a few good wagos couldn't do.

Would I have to add additional drivers if I add more strips? Or would the 600W driver be enough since there arent enough diodes? Im def going to have to add more light then later on

ok im going to take look and note the temps since this does not cover 5x5 like I hoped I will have o add lighting anyways so have to fix that soon as possible

actually the 301b and 301h are the same just marketed to different markets (h being for horticulture) so your lights were released in 2018 and renamed in 2020 to give you a false sense of being newer and better... They work the same regardless you can tell the difference between a lm561c and 301x easily as they are different 5630 vs 3030 maybe that's what bro meant IDK, but an interesting observation that a lot of people don't realise. :)

Gonna have to disagree with you though and there is lots of data anecdotal and not around to show kingbrite is an inferior product compared to meijiu and they are both dodgy anyway, so shit argument to have. Have been using both companies since lm561c. It just for the price they perform well enough. I'm personally leaning towards buying legit products now from people who deserve your money more. Innovation over imitation any day.

Yes from what I've read 301 h or B doesn't matter but apparently they are different?

My experience with kingbrite and meijiu the kingbrite has covenient connections and it runs equally on hot on both sides with a hlg, the meijiu connection are a hazard and the boards run 9c hotter at one side unless wired right and left with a elg/cheaper one.
I was sharing my personal experience.

And I 100% appreciate you sharing your experience because companies and products change along with their views and sometimes it is a good thing. A good sign of growth and apparently IQ.

the 301b/301h has been addressed a bit and by light manufacturers like greengenes (PLC) and stephenj (HLG) stating they were the same diode. These people deal directly with samsung and aren't just some dudes looking at samsungs (sometimes incorrect and inflated) data. It looks like greengenes removed his video covering this (or I just cant find it) but the video response from another person (at which he was called out for misinfo) is still up on youtube.. Also from another forum of an email from a samsung rep I think last year:

"The real story with the 301H is that they are identical to the 301B. They are just marketed to different markets and their data is presented accordingly. They both have the same photon or luminous efficacy (depends how you want to look at it). There is no tweaking or special phosphor used, the anti sulphurization coating and stronger bind wires (which is key in many harsher environments, but especially horticulture) is the exact same on both parts. But since they were gaining so much traction in the horticulture market with the 561c and 301b years back, they decided to cater specifically to that market and give them a unique data sheet that works for the specific industry; micromoles rather than lumens for the case of the 301H. "

Not sure if you still pay more for a 301H vs 301B but that use to be the case when buying from china and I would always ask for 301Bs.

Not trying to call you out or anything I love this shit and just want to know all I can about it and help others while doing so. If I'm wrong along the way, great! I'm achieving what I set out to do and learning. Appreciate what you have to bring to the table!

This! Some also say that the H tends to be higher binned; not sure if flux or voltage (please remember that lower voltage bin is the "higher" bin in this context; less voltage less power for same output; higher efficiency).
Can we finally put this one to rest; I'll bookmark your answer if I ever come across the question again.

Also reminder: when it comes to Ali I'd say most bets are off; pretty sure they get diodes that's not been full spec in qc and as such I'd say b or h is the same. I wouldnt mind it as such, they could have been failed in spectrum being just a smidgen of. I'd generally consider Ali diodes about half to a full bin lower than standards. But that's really not that much: a fixture that lets you make better use of the light you have over your space will easily compensate. A bit like Shane's thinking on migro: useable ppfd /w.
