The tent gets warm but not HID warm... and the bars are cooler than my Bava boards.How is the heat with those meiju bar lights?
I’ve always kept a 16” fan on the roof pointing down, that helps cool the driver and bars.

The lights I have that are similar to his (Majo) that run at 800 watt have a 480 and 320 meanwell.I see that you have an HLG-600H-48B. Is your other driver a HLG-320H-48B?
If so, your drivers have no internal adjustment screws (current or voltage), but each of those drivers come with dim+ and dim- wires so that a current dimmer (PWM, resistance, or 0-10V dimming) can be attached. Do your drivers have anything attached to these wires currently?
Which dimmer did they give you? God I hope it isn’t that white box style one with the knob and remote?i have the HLG-600H-48B and HLG-320H-48B and they are both connected to the same potentio dimmer wich was delivered with the light.
I noticed when you dim till zero the 320H connected bars (3) still give a bit of light while the others (6) are out.
Have you tried unhooking the dimmer then testing the lights? Seriously that dimmer is junk. I can’t believe they are still giving those out. I complained about them to Rita 2 years ago.thats the one , white box and flat remote
wasn't that the special edition for those that bought their NukeHeads housebrand seed for 70 bucks a piece? (most likely just a relabelled Lindaseeds for 1.50 lol)I think it has captain America written all over it, or the hulk, which we all know increases photon count.
Ok, the same thing happens with my Majo's. I have two 10 bar sets. If I get a power interuption the lights will come on, at least ones from one driver.... only they will be dimmed to the minimum.i have the HLG-600H-48B and HLG-320H-48B and they are both connected to the same potentio dimmer wich was delivered with the light.

So what did you do for a new dimmer, or did you just scrap it completely and not use the dimmer function at all?Have you tried unhooking the dimmer then testing the lights? Seriously that dimmer is junk. I can’t believe they are still giving those out. I complained about them to Rita 2 years ago.
Just a good old $3 potentiometer I went with. But my new mj650’s have a built in dimmer on the driver mount.So what did you do for a new dimmer, or did you just scrap it completely and not use the dimmer function at all?
I like the new dimmer on the MJ-650 better. The remote control on the white box isn't needed in my opinion.Just a good old $3 potentiometer I went with. But my new mj650’s have a built in dimmer on the driver mount.

1240 in the middle at 15inches?
This light (if true) would slaughter any light on the market right now at $580 + shipping fee. Is this even possible at this stage of LED tech? 3.0 efficacy??? Top of the line LEDs are anywhere from 2.6-2.8 umols right now for double the price.
They have another one that claims lm301B diodes instead of lm301H but its $80 cheaper. Im thinking its the same exact thing. Claims 2.7umol which seems more realistic than this 3.0.
Those numbers are bullshit. Ask them for there sphere test data from the testing company. I'll garantee you that MAYBE they'd hit 2.5, which is still quite good. Hell even Fluence doesn't claim these numbers! HLG Tested some of Chill LED's lights in a sphere test, and showed that their number were BS, I hope they test one of these in the near future. These Alibaba companies are all cutthroat liars. Don't beleive it? Good I've got a
3000 watt!!!! burple ( actual draw 135 watts ) I'll see ya cheap!
Did any ever find out what chips Chill are using for their growcraft?I always found it odd that they kept it a secret.
Shit my old BC Blonds hit 2.5 . Its about diode count. You need like 2000 diodes to hit 3.0 like the optic eight. 2.8 is easier to hit, like in a photo boost strip.Those numbers are bullshit.

The fixture has almost 2500 diodes.Shit my old BC Blonds hit 2.5 . Its about diode count. You need like 2000 diodes to hit 3.0 like the optic eight. 2.8 is easier to hit, like in a photo boost strip.

Terrible. Lol.
The optic slim 600h is 3.0 umols with blues dragging it down a bit. 2700 diodes to do it. You think they are full of shit too?Didn't say they were fake, I said the numbers were bullshit. I didn't say they were bad or junk. But I hate companies that rig their data to sell more. Hell if these lights are good, a 2.5 would be a number to be proud of! Not many companies out there have hit above even 2.6 yet.
And you can't extract PPFD from a light map, it needs to be tested in a sphere.
But hey, if you like being lied to, that's your perogative.
Thanks! I think we all pretty much know the baba sellers embellish on their numbers a bit.And yes, it's a good looking crop!
