Just goes to show what you can get if you keep your eyes pealed and have a bit of patience.
That's an epic price.

I soldered some diodes to these adura boards, they are 16, 3535 diodes in series. Well I was wondering how well it would work if I sanded down and split the circuit in half. It worked but kinda ugly, maybe I'll paint that part and mark the new + and - the pictures are one regular 48v and one modified 2 channel 24v. Xpg3 diodes are not the most efficient but still these are very bright boards which should be very easy to cool there is an isolated thermal pad and no dielectric to go through on the MCPCB, not to mention the thermal resistance rating of 1.3 I think. Which is a fraction of a lm301 anything

There has been so many new advancements in led over the past few years ever since the lm301b was proven to grow so well it's like all you see. I couldnt imagine starting a business and making a product that is exactly the same as everyone else's a million 301 diodes with a few 660nm diodes. And they all claim to be one of a kind. Lol. No wonder they're all going outta business. That's why I have lots of respect for companies going in different directions like GLA and Even Black Dog. The only way we will find improvements is thru testing different products.

What's going on with the specs for this cob? I can't find a clear reference to that particular chip. The specs only show the cxa3590 as having the Y (for 93+ cri), not the cxb3590?

I couldn't find the y CRI chips on there data sheets either it is possible they might have come out with that particular cob after the data sheet was made, I have seen that with cree before but usually they'll have a separate datasheet on the site somewhere. If you Google the part number and check it out on mouser or digikey there are a lot more stats. The efficiency ratings are at 84 watts, I think Itll probably be better at lower current. I want to see the color distribution somewhere.

Slapped 8 cxb 2540 3000k 90cri cobs to a 3\8" wthick 16"x16" aluminum plate with a million my wattstapped holes all over it. This was a chunk of metal I acquired from a homeless person who was pushing a grocery cart full of metal to the metal scrapping yard, down the street. I have bought several pieces from them over the years and have a nice stash of aluminum and copper tubing for diy projects I never finish. You'll see me on an episode of hoarders one of these days. Only reason I don't have more is cuz I need the space for my plants lol. I know it will work but how well is the question. I'm hoping for 200 watts. With a fan on top I bet it could handle more

.44 cents each cant beat that

Soldered my cobs and hooked it all up to a lrs350 and it's a beast the lrs350 was $28, cobs $0.44 each x 8 so 3.52 so a 350 watt light for under $40. Hard to beat

WellFan - Mean Well LRS-350-24 ultra silent PSU mod for Ender 3 by OderWat
This is a PSU modification which is meant for the Creality3D Ender 3, but may be used for other printers too. In the first step it replaces the original PSU with a Mean Well LRS-350-24. Then it replaces the original PSU cover fan with a specially designed partial case. This lets you use a 80 mm...

Lots of free STL files available these days to 3d print out a modified cover for your LRS-*** supplies, so you can add a bigger more silent fans and keep them running cooler.

I want to learn 3d printing metal or additive machining I've heard it called I work in a cnc shop, wish I could get a free day in the shop id make something cool. They let me do some stuff if I ask, usually to busy

1970s lathe can't forget this one I use it almost every day, don't make em like they used to

Or parts for a lot of them.

If I had a 3d metal printer, I would print out a full 1970s lathe first thing..

Can these be used as an alternative to the HLG-600H drivers? They are much much cheaper and not much less efficient.

Thanks. Yeah the 48V matches up nicely with the F series strips. Not sure why I never came across these previously could have saved over a hundred bucks per fixture. The ability to dim the HLGs is nice but not a deal breaker.

You could just switch off rows of the LEDS to save power with those PSUs, and to lower the output instead of dimming. Then again, you could probably also rig up a dimmer switch to it for a few bucks more..
