they are all pretty much the same tbh
Specs? Diodes, diode count, driver?
They are foldable 640 8bar 4x4’ is the area they take up unfolded. 550umol at 36” 120v-277v dimmable, have a master controller I can get too.
Just sold 50 last week to a grow in a Oklahoma they got them and are happy.
Text me and I’ll send pics n videos of the attachments don’t work.

i rented a par meter and I was getting really high numbers all over the tents at 600 watts per 4x4. How tall is your tent? is it a jardin extreme?
Diodes, diode count, drivers?

teh bar types never tell you the exact diodes. i got a gavita which should at least be good quality. the china lights i get say samsung 301h but who knows? I will say cree red is probably a waste unless they end up lasting longer than epistar. i did par testing and the cree isnt better and in side by side its not better, unless the reds all burn out in the lights with epistar- all my china lights have 100 percent of the led still functioning, i buy from kingbrite. I bought hlg direct and a whole line of led burnt and they have great customer service. i also have a used one and its got led burnt all over. id go china over hlg. Buy an extra light or 2 so you have spare quantum boards and ballast if things burn out. DID you see that bvv- i compliment good customer service. id stay far away from bvv.

Too busy to count buy one if u need to test. All I care about is the Umol and the warranty which is 3 years
Meijiu or Kingbrite even the medicgrow give you basic diode information like total count per diode type color, cri etc. It’s pretty easy to hand calculate and know if their efficiency number are bullshit.
I mean that would be basic information for someone selling LED lights right? How do I hand calculate on paper that that efficiency and usable light spectra is even remotely accurate if you don’t know what diodes or what the diode count is? Chinese lights use notoriously bullshited numbers. And I think three-year warranty is pretty much the standard now with any of these bar lights so I’d say these are actually worse than meijiu or Kingbrite. At least with those you know the diode information and specs of the driver.
the main question is are the led real and what bin. Neither can be stated as fact if you buy china. I buy china kingbrite and they tested as well as or better than hlg.
I literally don’t do that so I can’t do it to make a sale. I just buy the light hang it up and use my light meter cause what any Chinese company puts on a piece of paper is likely bullshit.
LIGHT METER NUMBERS MATTER more to me than anything else. I’m not trying to sell you, but if you want the best price for your dollar per watt and actual usable light measurements before you purchase it with measurements taken by ME on video with an American light meter not a SALES REP in CHINA be my guest mr. theres only a couple LED diode manufactures out there…they are all good. They all are going to lie about the bin number too, what are you going to do sue a chinese company for lying? LOL.
I’m a farmer first, salesman 2nd, I sell what I use.
Like I said, 550 Delivered New in box 640 watt 8 bar $550 delivered in the lower 48.
Running these exact fixtures on a 40 light double stacked project in OKC, build out is almost done.
Discounts available if you need quantity, 3 year warranty.

you know par charts are fake when they are even from one end to the other. I measured and by overlapping led i get crazy par. I need to shorten my hanger cables because the leds come with 18 inch long hangers to prevent a fire I guess. I use a big fan across them so I think I can get away with shorter cables. I have some plants that are like 6 inches from the lights and that isnt good compared to further. lets do math- 1 foot tall pots, 18 inches hanger length. 79 inch tent = 4 feet plants if they touch the led. so 3 feet is more better, I can get 9 oz each off 18 of them im sure, I just havent done it yet. i gotta get em up and running and get them in pots growing with vigor early so they dont get too large and all energy is buds. That number I mentioned IS outrageous given its a 1300 watt tent. but I know its possible.
I like the comparison of a top fuel dragster- its on the cutting edge of failure to do it like that but if you prepare and do everything right and the planets align its possible, ive had heavy small plants that fit that footprint- 9 per 4 x 4

Anyone have a lead on cheap dimmable or controllable 315w CMH ballasts

You should never dim a 315 from what I have read.
10-4 not so much interested in dimming them as I am controlling their on and off function through an RJ port

There is probably a relay that can integrate them in to your existing set up.
What controls do you currently use?

nothing yet i was hoping to find something plug and play already but i can easily grab a trol master with a relay and wiring circuits. i just wanted something cheaper/easier like the china DE lights from alibaba that are 50 bucks each lol

I’d pick up contactors and build the relay box.
