The Chinese Quantum Board Knock Off Builds

[Frank Nitty]

Check out atreum lighting. Tested vrs qbs on ledgardener forum and came out the same.

Thanks for the recommendation!!! Just bought 2 288.2 lights and heatsinks... Next week I get the driver... Didn't think I could find this in the US!!!

Yes let us know what you think of them.

Just got a notification from Mandy Xiao about a kit that they have for 236.44 USD out the door for everything, shipping and handling included... Now I dont know what to do... Maybe I should just buy both and do a comparison??? Atreum wants 219 for the 2 lights and driver, but they don't have double heatsinks...

What's the kit include?

2 288s,hlg 240h driver,double heatsink, and all the equipment to hook it up... Good deal or not???

Not nearly as good as that $368 4board kit.

Any first impressions of those disco r2t boards? Looking at trying out a few.
Bummer that you cant drive each channel individually.

No info yet I'm afraid.
I've been too busy of late.
I'll get them set up soon and do PAR Map.
I've a 185 driver to test them on.
The red spectrum seems to be the new flavour everyone wants to try and why not?
On the separate drive channel front I suppose chilled is the go to.
I'm too dim to dim separate channels so the disco board was the easy option.
I'm still eyeing those led tech de red strips. 2 of them between a 5 strip influx build would fit just nice.....

I set a Disco Board up last night on the Meanwel HLG185H 48A and a small heatsink.
Everything thing went well so I tested it a bit earlier today.

Here's the tools

A garden rake to support light

A couple of tape measures, spirit level, Apogee MQ500 PAR meter and sunglasses.
I run it for an hour to warm up and set the light to run at 102 wall watts and 0.46 Amps.
I use 240v


Hottest part on the heatsink was 40.7°C - 105f at 102 wall watts


Here's a PAR map at 1ft or 300mm away 102 watts



I also put up a reflective board on one side to see difference in par readings.

I bought the same light kit from Mandy, around $209 delivered.. works great for my 2x3. The power supply does get a little hot but i hung it up outside my tent and i installed a dimmer so I’m not running it at wide open.

Over all for two boards and double Heatsink I’m very happy with it.

 

[Moflow]

With reflective board number rise nicely

With the heatsink I used ~ 100 watts seems ok at around 40°C but to run these full whack you'd need something more substantial on the heatsink front.
Like this.


I had the board running at 235 watts and 0.94 amps full blast too

@Moflow do the heatsinks come from the same place or locally sorced and if local you got a link?

 

[Moflow]

No the heatsinks used are these ones from fleabay

An exact fit for the Disco Boards.

I coulda got heatsinks with the boards but I wanted to keep weight cost from China as low as possible and I had these lying around.... as you do

Maybe the PAR readings under the Disco boards are reading lower than they actually are as the Apogee PAR meter only reads 400nm - 700nm and these Disco Boards have far red and UV the meter cannot 'see'

 

[zypheruk]

Moflow you would be correct the apogee meter along with others that can not read them wavelengths. Boards seem great for the money.
Nice to see your still testing and publishing your findings.

Which apogee are you using? Sq-100 would have poor response to 660nm.

The Scope 240 with 5 x l09 lm301b strips arrived this afternoon so I'll check it out next lol

The latest, MQ500
