Hey guys, I've got an Led board that was from a light that an acquaintance purchased from eBay. It's one of the designs that jumped on the Quantum Board train and made one that from across the street looks similar. He said he came home and the light was off and wouldn't turn back on so I went and checked it out. One of the line voltage leads supplying the driver (if you could call it that) had broken loose due to a cold solder joint shorted to a resistor next to it and Bob's yer Unkl....dark ages. Anyway, the only thing the cover for the "driver" lists is: Iv: AC85-240, Ov: DC36-95v Ta 50°C and Tc 80°. The board itself is 11⅝X11⅝, mixture of warm white and red, claims 1500w he says he messaged before purchase and they said it's 100 "True Watts", only has two markings other than the component designation: MDA-225-GL-A and CR-2813S. Now, I'm not an electrical engineer but I can hold my own with a meter in my hands; but some ish is missing in the info for me to go fiddle fuggin around and blow up the board too. With a range of 36-95? The 95 is probably waayyy outta actual functional parameters and without knowing a max current rating..... Anyway, sorry for the long post, I'm also attaching pics of the board and what's left of the driver. Thanks guys.
Need some help, unknown board

You just wanna know what it is or what driver to use?

I was gifted three of these boards. Any more info on what they are or what to power them with? Might just use them for shop lighting.
Edit: Guess its an ebay china direct thing? I'm going to get them hooked to a cheap driver (7-22v ~40watt) and see what happens.

Yea, it seems most of the eBay specials run higher voltage. Hate that it didn't work for ya bud. It's a crap shoot no matter what you do but you gotta try higher voltage whether that means buying several cheap drivers or buying a good one and keep returning em until you hit pay dirt.

Sweet Username D00D. "The roots that grow underground are as big as the tree that you see, if not, it would fall down!"
@Airwalker16 ' Preciate it(even if the jokes on me lol) That's what a few folks called me cause it's what they always saw me drinking (211 Steel Reserve Black Can) and it got around and everybody forgot my real name(it's Percival) so it just stuck. T003L3V3N was born and ol Percy was never seen again.

You have enough info to make a good guess. If it's a 100 watt draw, and the driver will go to 95v, then a 1 amp driver would put out ~100 watts if the board is ~90-95v.
You could try this driver: https://www.rapidled.com/mean-well-hlg-185h-c1050b/
Otherwise, try to find a 1 amp driver that runs in the same voltage range (36-95v). This driver will support 95-190v.
So if that board "is" a 95v board, the driver above would work for up to 2 boards in series. But you really need to know what the voltage rating of the board is.....
