Interesting. 40" on the Meiju. Hehe. At ~500w. Nice photo of your "Strip Club".

Only reason I asked, was I am seeing a number of grows on tube where lights appear to be set at fixed height. Been raising my strip build as stretch occurs, whilst trying to keep in fairly close proximity. Makes examination and checking on things a pain. Knees are not young anymore.

I bought a 1000 watt meijiu majo V3.1 1000h-9 lm301h octopus and when it arrived there was no way you could tell if the leds were even from Samsung.
After contacting Meijiu their reaction was that they would not lie about it and i had trust them , they send some pics of boxes with Samsung written on it and that was not convincing at all.
I expected that somewhere on the led bars you would be able to read wich brand and type the leds would be.
Recently i got myself a energy tester and measured the light at full capasity, it only draws 880 watts from the wall.

Decide for yourself if Meijiu is the right company for you. For me they are disappointng.

That seems like a lot of watts. Two drivers? Is dimmer connected to both drivers? What temperature are the light bars after one hour running?

Not defending that company but the diodes don't come with Samsung written on them , unless your an expert you wouldn't be able to tell by looking at them.
You understand the company uses a pick and place machine and makes or buys their own pcb to place the diode in? So them having Samsung written on them wouldn't mean anything apart from they printed the words Samsung themselves.

Strange they sell it as a 1000w light and it seems to come with a 600w driver?
You would think they would wire it with two 480 drivers for 1000w.

I bought 2 650w and both are 650w and same par map as they displayed on their site. If you have 2 480 drivers then I thing your “energy tester” is wrong. CF3F65A1-6BDE-4445-8AED-6DA6D505D582.jpeg5368FE42-50C8-40FD-B925-CDE09936E544.jpeg

Im not 100% on how the internal dimmers work when theres an external dimmer also but I would take them black rubber caps out and get a tiny screwdriver and make sure they are both turned up to full power.

both drivers are conected to the dimmer HLG 600H-48AB and 320H-48AB the room temp is 29 celcius i have a airconditioner running.
Why do you think thats a lot? it should draw 1000 watts like they advertise the light with.

I was asking about the temperature of the heatsink on lightbar. Maybe reason for keeping wattage at 880W? So how hot are your bars?

please don’t buy into the hype of this light. Sorry to burst ya bubble but this is a straight up Chinese light. It literally says Shenzhen lighting Co on it, with a Chinese flag lol. only a fool would believe the advertising for this light. Sure you can get it for $582.00 + a $258.00 small shipping fee lol lol.
but for real though you can get the Growers Choice ROI-E680 from your local grow shop for $999.00 god forbid something happened to it, it wouldn’t have to go back to china
