Whoop! Blackened led tubes!

Whoop! Blackened led tubes!

Click to view full size image

This is weird i saw about a dozen sets of these blackened and sagging. This one was the only one with one tube slightly glowing. This is interesting to me because these might be on a t8 ballast possibly and causing the leds to arc out?

Something definitely overheated the LEDs.

The more you hate the LED movement, the stronger it becomes.

The electrician should've changed from T8 ballast to LED driver ballast!

.WoW. I've never seen a LED tub fried like that before

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

You think they would have smelled pretty bad when that was happening...

LED tube is a plastic or glass tube with a LED strip inside. I don't see any reasons for the LEDs in the strip, to emit desposites during operation that would blacken the tubes.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

I’m surprised that they haven’t caught fire yet. Also, you would think that if something looked like that they would replace it immediately to avoid a fire or customers asking questions. If I was in a store with those I would never be coming back. That’s some awful maintenance.

I am curious about the failure mechanism here. Most likely a defective component leading to cascading failure of the LEDs but a pretty severe one to let out the magic smoke and coat the inside of the tubes. And one is still partially working.

I thought the rows of F96T12 slimlines were best for large retail spaces. Easy to replace when failed and fewer required due to their length. If ballast has issues, just remove the lamps to shut off that fixture until it can be replaced. Simple and robust and I miss them and their inductive “thump” when they are switched on.

I'm lampin...

I wonder if these LED tubes are not compatible with the ballasts in the fixtures. All LED tubes I've installed at work come with a list of "certified" compatible ballasts. I'm sure that list is mostly so the manufacturer can say "well, you didn't use these ballasts therefore we're not honoring the warranty" but perhaps there are some ballasts out there that just aren't compatible. I would never use those LED tubes designed for magnetic ballasts because the ballasts weren't designed with LEDs in mind. Sure when working properly the LEDs might be compatible. But what about when something fails inside the tube? Who knows if that might cause damage to the ballast as well? Electronic ballasts are far more tolerant than magnetic ballasts to the "wrong" lamps so I'm less worried about those but you won't catch me using LED tubes on any magnetic ballast (unless of course my boss makes me lol). I'm sure these above are electronic though, since the fixtures look newish.

Please check out my newly-updated website! McCann Lighting Company is where my street light collection is displayed in detail.

What if and i know this is a stretch but maybe it could happen. Im wondering if these fixtures were F96T12 and retrofitted but the people who did it left the ballasts in and thought they could get away with hooking them up to the LED tubes.

I'm guessing these were originally 2xF32 fixtures, and were converted to 1-lamp...wondering if maybe they used high-ballast-factor ballasts instead of the common 'low' or 'normal' ones so it wouldn't be too dim. They'd be fine for fluorescent lamps, but maybe such a ballast would overdrive some brands of LED tubes?

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

Its possible, my other guess is these tubes are made for 120v direct connection but here they were connected to the T8 ballast giving them 600v and nuking them

Could very well be the case (i once smoked a direct wire LED tube on a T8 ballast as the sticker label had fallen off).

Old lighting is, and will always be, the best lighting.

This is why there should be only one type of LED T8 , not two

Or have the direct wire LED tubes standardize to use a different socket style so you could only install other direct wire tubes in these LED rewired lights. Also solves the problem of someone thinking the lights are still ballasted and popping a fluorescent in.

I think the T8 ballast LED tubes should be the only one. Dont have to rewire and it can take fluorescent if needed or desired. Not to mention in a surge the ballast takes the hit not the pricy tube and im not sure if 277v LED direct tubes exist

@ arcblue, I'm with you on missing F96T12. I don't even like going to stores any more. Led and T8 just don't excite me like a ceiling full of slimlines do. Lamp bans, gimping down T12, and now T8 just to make other less desirable options look better has made me realize just how corrupt government and big businesses are.

Keep government out of the lighting industry.

This is probably a ballast non compatible issue and the led tube had a fault and arced out causing it to get smoke coated
I suppose on 277V a direct wire led would smoke a lot if the driver had a failure

I'm taking notes... what ever the problem here is, it could also be a new issue with "instant fit" LED's... if that's what
these are. Regardless, this is not safe, at all.
Also, more LED fails have been taking place over here as well around where I live. Sigh... ahh well.

Theres about a dozen sets out in this cvs its getting gloomy as heck. It kinda reminds me when there a loose f32t8 and melts down a socket. Seems to be no fuse or shut down system incase a malfunction i wonder if it could be fire hazard if conditions were right?

T12/ t17 there's a reason they made heavy magnetic ballasts
