In my shop, I've got six 120V 240W LED "UFO" lights. One of them went on the blink, a couple of days ago.
It'll come on, then blink out. Randomly flashing, going dim, then going out. Lather, rinse, repeat.

I'm thinking it's just the LED driver, since it got a large array of individual LEDs. I'm quite sure that dozens of LEDs are not going to all get "flakey" all at once.

So, does anyone know of a possible source for an LED driver for industrial LED lights?
(I'm sure it's not readily available. You have to know that they'd rather just sell me/you another fixture, at $150 a throw.)

The part # on the lamps is VPL-HBU01-240WAD-50K-BL

More info... Intertek 5002090
The driver is 240CNL-260B

If 1 is dead, rest will be soon too.
PN for the lamp often mean nothing. You have to take it apart because often now these & many more have no driver you can replace easily.

If can replace the Driver...
Maybe the driver... But have to check for bad LED(s) too.

LED can short out, go "dead" intermittently, etc & just 1 w/ problems then part or whole lamp can flip out.

When have "High Volts..." Many LED you see often have 2 to many chips inside.

New Drivers often fail too even if you find good ones. More so mounted anywhere will get hot from lamp assem itself, high heat near ceiling/roof, etc.
If near the roof often air is hot > 100°F then Lamp needs to dump heat it's generated so heat inside of X is way hotter... Problem is most "consumer grade" stuff hate being run > 120-150°F

⚠️ If you replace a driver... If Lamp have Valid UL & other marked then those marked are no longer good & if have a fire later then I-co can void the policy/policies. Most business will replace the whole thing because of this.

Was typing out a long-assed rant about this stuff earlier but the Ogre posted, and... well...honestly, its probably less agita if you replace the whole unit.
because of how aggravating/pointless it is to replace a single faulty component...

unless you take down that faulty one and another "working" one, and break out the multimeter and go through and compare values and the unhappy one and pinpoint the one faulty component...

I've actually got one that I can transplant from an area where that much light is no longer needed, which I will probably do.

Ogre posted a link to the driver assembly. The specs are pretty impressive. This thing should not have failed.
It shows a MTBF of 200,000 hours.
It shows a max operating temp of 95C
It shows an operating range of 90 VAC to 305 VAC.
It also shows a 5 year warranty. (I may call my electrician and ask him to warranty it, since I've only had it for 18 months or so.)

If nothing else, I might break out the DVM and start checking components (if they're not potted). I repaired stuff to component level for much of my career.

Edit - Talked with my electrician today. Said that he's installed over 1000 of these things. Mine is the first one he's seen fail.
Yaaay. Lucky me.
Think he's going to try to have it warrantied for me.

The school I work at has a bunch of 277v LED ufo’s. The drivers go out all the time. Light cost $120, driver $30. Takes me about 25 min 22’ in the air on a one man lift.

Is This what you have? If so, I'm surprised it's about $54(USD) cheaper in Canada. That would be very unusual!



I'd never heard of this style light before. I guess I don't get out much.

Mine are similar. Not quite as flat.
