Cheap quantum boards on Amazon?

I had to order one of these to check it out.

i like the standoffs for the driver too

It looks a lot like the Samsung boards HLG has

That’s a mean well driver. So it might be decent. Looks like the hlg 65 v2 4000k I have.

My concern would be lack of a heat sink.

The hlg 65 and 100 dont have heatsinks. More power and you need them though.

I didnt look at the specs. Is the 672 the number of LEDs?

Might need to get a heatsink…

Do you think it’s a concern with the 150 watt driver? I dunno if you could see the standoffs to mount the driver

Yes i think thats what they listed, 672 off-brand LEDs? I didn’t count them on the board

This is like the one i got, im happy with it.

Any advice on adding heat syncs? Just space them out and solder to the back plate?

Slightly smaller boards but its basically the same thing.

How would you compare this light to the HLG 135 rspec ? Basically the same price.

Well, it has 195 more watts lol, the quality is good. Mine uses Samsung diodes and a meanwell driver, I would say the efficiency is slightly lower than what the hlgs are but you are getting more bang for your buck imo.

That HLG 135 looks very close and they give you the heat sync

Is it two boards or one? Or is the video just showing that can be daisy chained ?

There is a certain value In being able to contact HLG after purchasing not so sure on the other…China is a long distance phone call and they are not known for customer service…Just saying.
