Are you speaking from experience or hearsay?

My Kingbrite 240w's have been performing great next to my HLG QB 96's. Arrived in 6 days, good customer service and less than $0.70/watt is hard to beat.

What I stated was "pls don't do it from Alibaba. You can buy Chinese if that's what you want. However, buy through an American vendor and save yourself a lot of grief." Not don't buy. I don't knock anyone's choices. If they can be bought through an America supplier they will save themselves some grief if problems do come up and they have to return them.

So buy from an American supplier that just orders in bulk from Alibaba and then doubles the price? Yeah, I will pass. That defeats the whole purpose of buying a budget Chinese LED light. I haven't had any issues with customer service from Kingbrite which is an Alibaba supplier and their shipping is faster than a lot of places I order from that are located within the US.

Are you shitting me? Grief? What circus did you ride in with?
Okay, trouble does that sound better??? "pls don't do it from Alibaba. You can buy Chinese if that's what you want. However, buy through an American vendor and save yourself a lot of grief" Pertaining to returns and resolving problems

Glad it works for you and double is a bit of a stretch.....Geek Beast Pro on Alibaba vs GBP website about $150 difference for peace of mind.

Every 75 pages of this thread there’s one of you dimwits piping in that never bothered to read the rest of this thread. Go ahead, shit it up further with your advice.

Peace of mind. Do you sell penny stocks?

Most of the American vendors of alibaba-sourced gear are fly-by-night middlemen who order a shipping container load of gear to sell, mark it up, pimp it on Amazon or eBay, and disappear when it's all sold.
You actually put yourself in a worse position for warranty claims by assuming any of those dudes will be around in 2 years.
Kingbrite, Meiju and a few other top alibaba market companies have been around for much longer.

First, I want to apologise to all of you on this thread. At first I couldn't understand the hostility. I had several tabs open and saw the initial post that I commented on and gave my 2 cents. I didn't realize what your thread was about. That's completely my fault. It was like a giant fuck you to all of you. Definitely not my intent and your reaction was justified. Almost 220 pages of a thread and I was oblivious to it. Mea culpa. I hope you'll forgive my rudeness. Was not trolling you. We're all pursuing our passion.
Peace,

So my 650w Hortibloom showed up today...

The panel looks sexy compared to the grey Meijiu's but the mounting setup is a joke. The hinge/folding hardware they use is bulky af and looks like something Grandpa would have on a DIY tool box. The threads on the Eyelets that the hangers connect to are far too long. They dont flush up to the frame so there are quite a few threads showing which makes it look poorly done.

Hortibloom has 2-point cable slings that they sent but when you use them you end up losing almost 1' of headroom. I had to use x4 yo-yo connectors. They also have brackets that slide down on each end of the frame and that's what the eyelets thread into. Unfortunately there is no reference mark as to where the center of the panel is so there is multiple adjustments needed in order to level the fixture. I know i bitched about Meijiu's being a PITA to level especially when you dont have access to all 4 sides, but I'd still rather mount a Meijiu VS a Hortibloom now.

It also came with the Inventronics driver which says 600w max yet their dimmer says 650w and they advertise it as 650. The dimmer appears to work far better in the lower %'s than my Meijiu's do.

I asked for 3500k (same as my A8's) but these look like an HPS compared to my other panels. Super orange VS the white of my Meijiu's. There is a substantial more amount of visible red diodes on the Horti's but I'm surprised in the difference between the two.

I'll take some pics once I get back to the pad tonight.

All in all so long as the performance is there, the cosmetic issues are minor. Just makes a guy question what he's really getting when paying this much for a panel where the small things that shouldn't be an issue end up sticking out.
I will post a summary of the Hortibloom 1000W when I get it, I was told it can run at 1100W by the sales rep. I think that is Ridiculous and its definitely not a output I would feel comfortable with as far as diodes, driver longevity and uhhhh safety lol.

Not to be dumb but if you were going to be buying another light today which would you choose the meijiu or the kingbrite?
If your going to go through China then I'd go Meijiu. What I like about their panels is that every piece is independent so if you have an end bar or strip that shits the bed you can have a replacement one sent. This Hortibloom is all one piece and the rubber gaskets that seal all the connections between the strips looks shotty af in some spots. I can't speak on Kingbrites sorry.

I wish I would have looked at HLG's website again prior to ordering my 3rd Chinese panel. A 600 Rspec is only $1,188 CAD now. When I was peaking at them way back they were considerably higher.

I asked Hortibloom why they advertise the Mega 650 as being 650w yet the Inventronics driver says 600w MAX. THis is the response I got...

"Hi, thanks for your reply.Mega Plus 650w led use Inventronics driver EUD-600,the driver max power can reach to 680w,it's no problem."

I'm no lighting pro but I must be missing something here..

I asked meijiu the same thing and the manager was the engineers tune them to run 650. I have seen a few folks here say they got 650 at the wall from their meijiue with the inventronics though

Its the same way as a 600/1000w hps actual at the wall power consumption will be a bit more than 600/1000w, cause you have to add in the consumtion of the ballast. Think of it as 600w at the board, and even so many times it will be a slight bit higher as mea well and most manufacturers will over spec their drivers: generally they have 8-10% more output if not dimmed

THank you for the info! So I shouldn't be running them at 100% then?

Didn’t see your earlier post to cite more about this question.I watch and tune my wattage for every cycle depending on how many tables I’m running, how big are the clones/mothers. Size of area it’s covering etc...I’ll assume you have some plants under a 4x4 that could use all 650+ wattage it’s fine. Now if you go over a certain ppfd then your essentially just wasting watts. If you want that hps 1000watt comparable with led then I would just run it max or slightly under if you have big plants

I see. There's certainly nothing wrong with getting "H" designated lm301 chips. When I was first getting into these quantum boards it was a bit confusing for me. GreenGene and several other industry trusted individuals (Stephen from HLG) confirm the lm301b and lm301h are the exact same chip. Just a bit of marketing confusion (intentional or not) on the part of Samsung. I'm not sure what boards are hot in this thread presently, but here are the two 110W boards I just ordered from Shenzhen Yixiou Technology Co on alibaba for $187.60 with tax: https://www.alibaba.com/product-detail/Full-Spectrum-110W-qb288-Samsung-lm301b_62512497620.html?spm=a2756.order-detail-ta-ta-b.0.0.6b8d2fc2MkFLbc. It has a mixture of 3000k and 5000k lm301b chips, IR, and UV.

This is my 2nd order with Yixou. My first order was a 660W board with the same chips. The 660W board is basically 6x of the two boards I linked to above. It works great, but I feel breaking the boards into smaller panels produces a much better spread of light over the canopy. Cramming too many chips and boards together in a small frame creates a lot of intensity that I feel is best spread across the canopy creating a much larger and more evenly distributed light foot print. I believe HLG addressed this very issue with their new Scorpion boards which separates the panels rather than cramming them all together in a tight package. The vendors on 'baba will have their own Scorpion's soon enough for half the price of HLG.
B and H are the same diodes, only if you are sure to get top bin B diodes, and not some of the lower bins. The H diodes don't come in a low of binning as the B versions do, which means that you might get "the same B diodes" which produce less photons compared to their H counterparts. If you are sure that your manufacturer only uses top bin "B" diodes, then yes they are all the same, which is why Steven at HLG would answer that way (HLG only uses top bin diodes).

Good man, thread was not made for keyboard warriors, but for people trying something different and posting their findings and keeping things civil and growing herb off course.
Thanks.
