Failing f32t8 highbays

Failing f32t8 highbays

Click to view full size image

These are at the gym at the church. Only 4 fixtures are working properly, and the others are falling apart. Literally. I am not sure what the plans with these are right now, but almost every one of them has a failing ballast. 2 of the fixtures have failed completely, and others have dim flickering lamps in them. The whole lot was group relamped last year, and since then, almost every fixture has suffered ballast failure. There are 12 fixtures in tota.

If I can suggest the ballasts that they order to fix them, I might suggest f48t12 HO ballasts from Topbulb ($7 apiece, so they might get those.) Plus, it would be a lot more reliable. If only I could have got the highbays out of the ice arena that was demolished, they would have been perfect for fixing situations like this.

You're not going to be able to install F48T12/HO lamps in these without also replacing the lampholders, and they still may not fit. The lamps are also much more expensive than F32T8s. That said, I'd LOVE to see a 6xF48/HO highbay.

I like my lamps thick, my ballasts heavy, and my fixtures tough.

Would a large HO ballast fit in one of these?, if it all worked out, a six lamp F48T12 HO would be super cool and bright

Unfortunately alot of fixtures made nowadays have a smaller ballast channel and cant fit a standard ballast

If the larger ballasts didn't fit (which wouldn't surprise me), the HO ballasts could be mounted on top and the wires run through rubber grommets into the ballast compartment. That's how I will replace the backwired GE ballast on one of my Miller preheat fixtures once it fails.

This would be an awesome conversion but it would be very costly. Instead, I'd suggest using higher-quality electronic ballasts and full-wattage F32T8s. Also, if the temperature gets high up there at the ceiling, some large industrial ceiling fans would be a good investment to circulate the air around.

If HO lamps were to be used here, Iwould recommend using 4 HO lamps on one of these, leaving the middle sockets space free. It would reduce the heat a little, also the weight that the fixtures mounts have to hold and the cost.

Rapid start electronic T8 would be pretty cool, especially if each pair of lamps is in series

Can you tell whether these are programmed start or instant start?

Remember being drafted to be "electrician" for a radio station---replace failing fixture ballasts.Instead for the cost and time--replaced the WHOLE fixture.Was faster-and really cheaper.And in the deal you got a brand new CLEAN fixture.The station manager liked that better as well.This was in the days before I turned to a "flashoholic" and started collecting lights.That project got me interested!

Oh good. At least the wiring is all there for HO or rapid start electronic.

If it got 240V or 277V you could just go magnetic with European ballasts....

Wow. Here they installed all 6-lamp highbays on motion sensors with /841 Sylvania XL life lamps in 2011-ish and they're all still going (a couple lamps have failed but no ballasts). And they're instant start too!

If those highbays have as much space around the lamps as the one shown below does, you could most certainly put T12/HO lamps in there. You would probably need to cut away the reflector a little to accomodate the thicker lampholders, and the ballast(s) would likely have to go on top.



Now I really want to find a cheap one of these highbays and build what would essentially be a modern version of the old preheat industrial fixtures with the top-mount ballast.

Speaking of which, what about making a PREHEAT highbay? You wouldn't even need to use different lampholders if the fixture was programmed-start from the factory. I might actually have to try this one someday. I even found this, which comes without a ballast and has non-shunted lampholders.

It's funny that the "LED-ready" highbay has the polished reflector. LED tubes wouldn't even make good use of it.

It looks like a stock photo. I particularly dislike them. I want to see what something looks like individually when I go virtual window shopping. Stock photos make it boring.

Why I like LEDs on top of other lighting tech?
LEDs = Upgrade 95% of the applications. (That is if you avoid eBay's LEDs).


LED brainwash? No, people uses them cuz they work well for them.

just get some better ballasts, go with pre 2005 advance electronic, if those full sized ballasts would even fit in there. I have a 6 lamp highbay installed at grandma's house that has a very roomy ballast channel that'll probably get a T12 conversion if a ballast fails, 6 F40/950 lamps would be really nice

I see them. Did you use flash by any chance? They're usually floating dust specks out of focus. Nothing supernatural I'm afraid.

Yes, I used flash. I had just stirred up some dust on a shelf, so that is what you see. Sorry to disappoint you.

UPDATE: They ordered some new lamps and ballasts (new ballasts are instant start, and these fixtures get switched alot, so more maintenance) and they ordered ALTOs. I advised them to get something better like Sylvanias, but they ordered them anyway. Hopefully they last.

Why would they order IS replacement ballasts? That requires an overhaul of the wiring which means more labor. Would just make sense to buy replacement PS ballasts. My school's highbays are IS but the lamps are LongLife Sylvania /841s. A few have failed (understandably since they're on motion sensors) but no ballasts yet!

I don't know why they ordered IS ballasts. I was kinda hoping that they would replace the failing lights with PSMH highbays, so I could try and get one of the fixtures and do an HO conversion.

These building owners that ask for these weird T8 or T5 or LED 'Green' alternatives rarely learn their lesson it seems even if half their lights failed.

I personally do not like T8 lamps but because I've found a supplier of new rapid start series ballasts that work exactly like magnetic and lamps seem to love them, I'm okay with T8 a little more.

I think the lights are original to the addition, so that is why they have never been replaced. I was hoping that they would replace the ones that had dead ballasts with new PSMH highbays, but I was wrong. At least they are repairing them rather than replacing them.

Thats sad. When will people learn they were better off with good old magnetic T12 or HID

Even electronic HID is more reliable than these fixtures!!

What if I told you you could save 100% of your street lighting budget? Don't believe me? Buy an LED street light and run it for a week. the results will leave you in awe. (Aaaaaaand maybe wondering why you swapped that 70w SON)

Well sort of. They just retrofitted them with LED tubes, but they aren't as bright now. Plus, some of the tubes have already failed. I have suggested putting up 250 or 320w PSMH highbays just because of how hard it is to keep these all working, but they said they can't really do that because these get frequently switched (they rent out the gym all the time) and so re-striking would be an issue. They also can't do LED fixtures because of how much they would cost (and because if they failed, they would cost a lot to replace).
