Uh-Oh! The Renovations Aren't Even Done Yet!

Uh-Oh! The Renovations Aren't Even Done Yet!

Click to view full size image

The lights still even have plastic wrap on them to protect from dust/debris from the ongoing construction in the building. And this one is dead already. This is the only one I've seen that's dead (only about half of the lights are hooked up anyway). Not sure how easy these are to service, but they're single 8ft sections. I think these are also Day-O-Lite fixtures. Not sure what the drivers are but some of the other Day-O-Lite fixtures had Advance LED drivers.

One thing I noticed is that the sprinkler heads are recessed above the drop ceiling and have white caps that go over the holes in the tiles (these don't yet, but they will). How does that work in the event the sprinklers go off? Are the covers held on with water-based glue or something?

Can't deny the energy savings here though. What uses less energy than a non-working light? Guaranteed to save 99% on energy costs! (since the driver is probably still using some minuscule amount of energy lol) Now that I think about it a dead incandescent lamp would save 100% since it wouldn't use any energy at all...

I always assumed that with those concealed type sprinkler heads that the caps were some sort of plastic with a really low melting point. Either that or they're just on loose enough that they're "blasted" off by the water pressure if the sprinkler head activates.

Gross! I think the caps they use on the sprinklers fit loosely within the dropped ceiling so that they'll get blasted off by the water jets. Or they fall when the dropped ceiling is soggy enough.

The sprinkler covers are actually metal, and soldered to the base with a low temperature solder, they will normally fall off at 135 F and the sprinkler doesn't go off until the head gets to 155 F at which point there is a fire in the room.. And at a good guess the plastic wrap probably isn't helping the lights with cooling, they might end up testing out those sprinkler covers sooner then they expect..

Professionals would bring there own lights not create more work, a few 400 watt MH wobble lights would light that room up nicely and then they can leave the plastic wrapped lights off..

LED dead before the job is even finished - so much for the 50,000hrs life or whatever lies they claim.

They do run hotter with all that Plastic wrap on them, though for the low power of this luminaire (~40W for 4ft ?) i dont think it overheats much even with the wrap on. It would have to overheat by many 10's degC to burn up because of the Plastic...

@ Lodge: Thanks for the info on the sprinkler covers though. I always wondered how those worked. I see them fall off all the time so they must be very lightly soldered. A lot of places with drywall ceilings use these, but this is the first time I've seen a school use them Typically aesthetics are not of much concern in a public school lol.

The rooms all have big windows so there is no need for the lights to be on. The lights were only on because I turned them on for a picture (I wasn't expecting one to be dead) and I turned them off after the picture. Most of the rooms have daylight sensors on the lights and they won't turn on unless it's overcast anyway. Certainly the plastic wrap is not what killed this.

LOL this is a familiar sight , our first load of LED battens we had at work, went purple in their first year!, they were all replaced under warranty, but one of the new ones fired up with a couple of diodes out!

AHH HAHHAAAHHAHAHAHAHAHAHAHAHAHA!! I'm sorry but this is absolutely pathetic. An LED fixture that's already gone before it
even got a chance to begin it's job? That might be a bad sign for other fixtures to do the same here given a short amount of time.
Then again there may be more to it. Maybe something happened and the electrician didn't get the chance to complete that particular
fixture and either forgot about it, or made plans to come back to it after building renovation was complete. I'm trying to defend this
just a little... because a fixture failing within a short time period like this is absolutely inexcusable.

Not an uncommon site these days sadly... when they built a new library here they used several LED highbays in places where they could have used fewer 250w PSMH highbays. Within a months at least 1/3 of the fixtures were completely dead. They replaced them and the same thing happened. They have to replace them every few months when they could have just used 250w PSMH fixtures instead. They aren't just cheap eBay lights either.


I always assumed that with those concealed type sprinkler heads that the caps were some sort of plastic with a really low melting point. Either that or they're just on loose enough that they're "blasted" off by the water pressure if the sprinkler head activates.

The plastic caps are held on by 2 small pieces of wax with a low melting point. Its not uncommon to see them missing their covers in buildings with no air conditioning. You can find videos of them activating on Youtube.

LEDs = Downgrade 85% of the applications.
I identify as a 400w mercury vapor street light.

I mean I knew LED failures have been pretty common, but when it begins to happen just days, weeks or even a month after installation, that's
truly inexcusable. I'm still defending this a tad bit though because there is a chance the electrician may not have completed his job
or something. If it's not that, well... Very pathetic excuse for supposedly reliable lighting.

That is extremely pathetic If it was my choice, I would've just sprang for instant start T8 at least. I will accept and tolerate LED lamps, but only the ones that are as simple as a relamp. I basically only like the filament ones. These proprietary throw away fixtures are GARBAGE, they should all get ripped down and melted into a nice hot puddle of slagg.

All the schools around my area have installed rows of single lamp T8 wraplight strips, surfaced or stem and in some rooms, they actually mount a few of the same fixtures on the back of the main rows facing up for the uplighting. Crafty

What happens if one of these LED fixtures are dead though? Do they actually have to replace the entire fixture in this case?
If so, that's just another major addition to this.

I'm thinking the fixture was defective when it was put up. They can't replace it on the spot since they only order so many. And the defective unit needs to stay up so it doesn't get lost before a warranty claim or whatever is made. The electrician probably made a note that the light didn't work and they'll come back to it at the end of the renovations. I'm not sure how these open up. I do know they lock into one another with a plug and a false end cap is put on the ends of the rows to cover up the plugs and stuff. The fixtures I saw were laying on their backs so I only saw what I can see with them installed. there could be an access cover on top, which would make it easy to service but if not, a nightmare.
