I found these in the scrap bin on work. I don’t know why they have been thrown away, haven’t had the chance to open them.
So they might not work or it might be an easy fix.
Nevertheless, what to do with them?
Or what would you do?
I think I will definitely make them battery powered, together with a handle.
So should I…:
Keep them as they are and just make it battery powered?
Upgrade the COB and driver?
Putting multple quad setups in it?
First one:
Second one:
I have two of those in my garage putting out 100 watts each at 4000k and they light up everything. Yours says 160 watts at the back. I would connect new wires at the back and use them in a large work space or outdoors. By the looks of it, some of the emitters may be burned out on the second one.
I would if I had the space 
.
I don’t have the possibility to use them as they should be used.
So that leaves me with whatever I want. :sunglasses:
I’d use a PIR detector and a relay to light up the yard when someone enters an area of the yard they don’t belong in. Or a beam across the driveway that turns the light on when you get home.
Got an irritating neighbor?
Needs a high CRI Yuji cob 
toddcshoe, a beam across the driveway would light up the whole street 
As I said I don’t have a yard that big. Not like many of you do in de States. 
Also, no irritating neighbors here…
Definitely want something in the high cri department.
I don’t know how they look from the inside so I might be limited by the design of the lights.
I think the single COB in the middle of a vast “reflector” (that doesn’t actually reflect anything) is pretty boring. Perhaps, if you can, remove the reflector and put a bunch of Carclo quads in there. If you have a flat piece of sheet metal, you could make a “shield” with holes drilled in it to go around the quads and cover all the stuff in the background (the only real purpose of the “reflector” in these lights). If not quads, maybe several individual emitter TIR’s or reflectors.
hmmm….
Seems you found them where they belong, i.m.h.o.
LOL
I had one mounted below my carport, but my neighbors had some complaints about it, it is fitted with a motion sensor to be able to see something when you arrive home in the dark.
The problem was, it senses our cats too… So it would light on randomly in the middle of the night which awoke them
Now i have welded a nice stand for it, sanded and painted black. it swivels as well and it serves as a working light now
these are easy fix for many uses.
you can buy driverless cobs if you are okay with the 50/60Hz flickerrrrrr
I’d just wire them to my common socket plug (mine is a 3pin uk plug) and screw it into a stand for a diy work light.
You can use it as a home stand light if you use a slightly lower wattage driver on these 50w led to prevent it being hot indoors or just blast it with max 50w for winter use
But looking at your pics you might need to custom re-do the bracket mounts
If you’re doing a battery mod you could always utilize the ballast section as a battery holder while the LED section slap 2x XHP70 of different tint and a appropriate driver
Yeah, and the nasty tint and low CRI…
its a gamble I guess. I had a few 4k warm whites they are pretty good in color. Very XML-4C tint imo. No nasty purple or pink hue.
buying more from same vendor they came in weird piss yellow with odd purple tint.
Its random but I guess I was buying it for someone else who want it cheap. Overall these driverless all come with nasty 50/60Hz power flicker
Haha, yes they definitely look like crap.
But that’s what I like about them.
Imho they have potential to become something great.
Something like this. Not really interested in using them the way they supposed to be used.
