Who told you that? The supplier? Generic, rather than custom built. There’s nothing custom about them. I agree with OldMotherSativa.

The specs are garbage tho. What do you see in them? Look at Bridgelux Eb2 strips or opulent strips. Cheap and top of the line performance. Iv always loved cutters products.

They haven’t published any 3rd party testing yet. And they haven’t started shipping them out yet so no one has had hands on them. What’s advertised is top of the line. Their other products are top of the line as well and have proven this thru 3rd party testing. I have several of their 144.2...

Ahhh very interesting. I would think these tests and approvals would be more discussed around here. Does HLG have these approvals? Being someone who uses Chinese boards, what do you think about this MoFlow? Have you experienced any degradation?

What is LM-79 & LM80?

Damn, now I really want to know how it tests out. For that price, this is a screaming deal if everything checks out. I tried looking up the driver and couldn’t find anything online. I don’t like that.

I would very much like to see the results if you do choose to test with your multimeter. I wouldnt expect any other answer from those type venders. Same as the advertised diodes used. You never really know. But if they can achieve such claims, hats off to them! Is ETL a European code? How...

To take it a step further, you can measure the voltage and current on DC side of each driver to confirm what the system is actually outputting to the LEDs. I suspect it’s a good amount less than 640 because 91% efficiency is pretty got dang good for a light from China. That’s actually very...

They probably advertise 640w as in the power sent to and consumed by the LED. Within the system as a whole, their will be inefficiencies such as losses at each driver. 640 / 701 = 91% system efficiency Experts, please correct me if I’m wrong in any way. I had a hard time putting it in words.

What do you mean by refined? Chip answered your question best.

I’m no QB expert although I have several Atreum boards. I believe the vast majority of QB users don’t use any TIM/grease/paste.

The gap is 1.5-2mm along 3 of the sides. Much to large of a gap for paste I assume.

I guess part of my reasoning for not using the plate heatsink is because the 144 isn’t exactly flat and only has 4 holes in the corners so it’s not flush with the plate. My thinking is that heat will not be efficiently transferred and between the two surfaces and will be trapped in the air...

I have a few 144.2s mounted to individual 12x12x.125 aluminum. I’ll be mounting 4 of these to a frame. Should I keep them on the aluminum plates or just mount them bare to my frame? Is the plate value added enough? Or would I just be adding unnecessary weight?

Unless your ambient is really high then that would work good. Here’s a link for Eb gen 2 thermals. https://www.rollitup.org/t/bridgelux-eb-gen-2-thermals.957453/ You can even run them bare at 1.050

ok ya thats when they will be in. I was just letting you know they aren't in stock now

May

Those Bridgelux strips in your link aren’t in stock. Just fwi

Atreum boards will do you well. I have several of the 144.2s and they have proven themselves many times over.

Dang man HLG has excellent options for budgets. And Atreum even cheaper like Airwalk said. For the same $250. Check em out on amazon
