How to find/replace the led driver

i have a perfectsun mini and not been using it all that much but my warranty ran out. i have been noticing lately that the one boards leds keep continueing to blow leds. i got the boards replaced while it was under warranty from my own stupidity thou, turning the light off and on too fast. but Ive got the rest of the non-burnt leds left over from this to fix leds blowing out. But i had one go out and I thought it was from the heat that day, and humidity that kicked on my dehumidifier. but then about a week later, one day theres another out led. So as I took it out to check it, i plugged it in and one of the boards would take a second longer to even start to light up then the other one which comes on slowly and brightens up within about 3 seconds. then a second into turning it on the 2nd board will start to come on, dim, then it seems to go out then light up and almost be at full brightness.
SEeing this i was thinking, the blinking as the light comes on is blowing out the leds one after the other. So i need to get this driver replaced. But how do i light them up at the same strength without blowing out the led diodes and everything? How do i find a replacement when i cant find a replacement to buy with the same model number as this one to run this with? NLGI-70PC-063A was the part number on the driver. i have a watt reader you plug stuff into to see how many watts it uses. i forget what this light shows but its right around 125watts plugged in, and all i can find are what they say are 60 watt drivers. id go over but i want to push the same energy through the leds as right now.

no. I just want to know how to get or find the right driver. if this does anything or helps, the board they drive are 30 diodes in it. im guessing 3 watts. some things i wrote down off of the driver in it
50/60hz .76? PF7.9
output 65-100V
constant current 600mA
Max output 70watts
not sure what i need to get for this 2 board 125watt light. i could test the watt use again its been a while if i remember. i realy just want this thing to work. sure i could replace the diodes i guess maybe but this works fine and i just want it to continue working.

2 LPC-60-700 Would be close

Looks like he found your exact driver for you. Props to the man.

ok well, its not teh same one, i need it sooner than later so i stop blowing leds, i dont have multiple months to wait on ali-express or china. every question ive asked has been answered with let china figure it all out. how do you find the right driver? and does anyone know maybe of a compatible one thats just simple plug and play replacement? do i need more information? it came out of the perfectsun mini. and it said DIMMER on it.
there is no lpc-60-700 that i found, one site even says it doesnt exist. if i was to use a 700mA one instead, how would i know how much power its pushing to the leds or if it would work with 3watt leds or if theres some way to adjust them when you get them? idk

RapidLED.com has them lpc-60-1400 just split Into 2 parallel strings

ok. now its blowing leds on the other board. whats causing this light to blow the leds randomnly? i havent had the board for even a year in operation. the old one was about the same amount of time but I flicked the lights on and out. I dont know if the leds are high quality or not or if this is the sound or look of bad quality leds.
so what else could be causing it? the leds blowing on the other board could be a false thing but. whats a good brand of 3watts leds to use? this light has 2 boards with 30 leds soldered to an aluminum plate. im thinking this plate is wired together if one led goes out, the others dont. could it be the board some problem with it that tthe leds are soldered onto?
the leds have little legs on each side, one longer and the other shorter. 30 leds to each board, each board having that 70watt driver. little under 2.3 watts going to each seems like.
any suggestions or ideas what could be blowing the leds? i still have not replaced the other driver. i could try making a video real quick. i took some pics of the inside too, if everyting seems like normal wiring, ill try to wire the maxwell driver i got in too idk maybe.
the little board they all connect too, seems normal but theres the thing on the end i took a picture of it goes to a screwed in thing on the board then out to the connector, then back out from it, around back to the thing screwed in to the plate/board, aluminum there thing. not sure if thats a safety thing or not or an adjustor.
heres the video of it starting up https://streamable.com/zkkvdz
if any one has any ideas what could be blowing the leds or knows, im looking for tips. thank you.

ok moflow reacted to my yesterday post liking it.
so does anybody know what is causing my light diode leds to go out? also the blinking side seems to of swapped on me, as i said it was the side the leds were blowing on the driver seemed to of blinked i swear. i deleted the video i think when i made one over it. and i swear now i know the other side is blowing leds and when i went to make a video to show, the other sides driver is blinking taking its time coming on. but maybe i had it backwards...?
does any of this seem normal or make sense? and whats causing the LEDS to blow? should i rewire something or maybe, idk is something loose like the odd weird contraption i took a picture of in the light? the board that has all the lights and drivers pluigged all into it, has one plugin, one wire goes out of it back to some odd screw in thing on its frame, then another wire comes seems screwed on to the same thing coming out the other side, goes back around to the other pin on that plug out, i tried to take a picture of it if you can see it.

what im saying is i didnt come to here to ask how to fix my led light to find out were to contact the guy who made it at. it is out of warranty, btw i found a driver too, at least i guess but i wanted a replacement not from china same thing from there.

i guess i was looking for led knowledge help. i dont need to get the contact info for the guy who made the perfectsun mini

You need to fetch new fixture. You're using slug diodes I can tell. Cause they sure ain't SMDs

but how do i know its my "fixture" maybe its just the "leds"? i dont think i want to replace the ..
boards
heatsink
fans
drivers
wiring
electrics
leds
for a blowing driver. i posted aton of videos and pictures, moflow upped my comment from the manufacturer which i had already contacted before he suggested it.
so idk its blowing the like i said read, my just made comments

here is some pictures of the diodes on the board, i measured them at the round part its 8mm wide. whats the difference between a slug and smd? these are soldered on right now. so what is a slug? these diodes have started going out after abut a year of use, doesnt sound right for a light that has a 2 year warranty, and i got new boards after having it for a year. so these are a year old.

Slugs are what you have. Housing with metal tabs.
SMD means surface mount diode and is placed onto a pre soldered board and sent through an oven to heat the solder and cool all in place.

ok you can add heatsinks with, thermal grease, thermal glue or even soldering.
whats the point between the difference between a slug and a smd? basically this is what your talking about https://en.wikipedia.org/wiki/Heat_spreader
and either you use solder or a grease or thermal glue to attach the chips to the board.
i dont undertand then any. are you telling me i need to solder teh chips to the board? how does this relate to them blowing or not? as far as i understand as long as the grease is good the heatsink should work no matter if soldered or what type of thermal interface material you use. this isnt far from just using a processor heatsink, so i know what this is.
whats a slug? whats the difference between that and a smd?

how come some of the blown leds on the old board, will come on momentarily then go out as the light gets up to full power?
