Philips F32T8/TL741 Universal/Hi-Vision

Philips F32T8/TL741 Universal/Hi-Vision


This is an older Alto. These Universal/Hi-Vision tubes were usually good - some would go mercury starved, but most seemed to last for quite a while. The glass is of a normal thickness, unlike the new Philips paper-thin tubes that implode if you hold them too tightly!

I have a GE F20T12/CW (same as the one seen here) that has a hairline crack at one end. It is in service in our kitchen fixture (4xF20s) and works fine.

I have a lamp just like this. I use it on a 4-lamp instant-start ballast alongside three newer Alto II's, and there's a noticeable difference between this one and the newer lamps. This lamp lights at full brightness immediately, while the Alto II's are dim in the middle for a minute or so until they warm up.

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

Yeah, these weren't bad lamps. The Alto II lamps (particularly the Econ-O-Watt 28W version) are awful - poor light output, mercury starvation, and terrible cold weather / drafty location performance.

I recently bought a whole case of the Alto II's (32-watt, fortunately) when I installed instant-start troffers throughout my large unfinished basement. I know, I know. I would have preferred rapid start fixtures, but for what I paid (less than $15 each on Craigslist) I wasn't going to complain. Of the 16 ballasts in those fixtures, 3 were dead, but none of the good ones have failed so far. As for the Alto II lamps, I haven't had any issues so far besides the uneven light distribution at startup, which isn't a big deal to me. The troffers came with 28W Sylvania Supersaver Eco 835 lamps, about a third of which were dead and the others well-used. These lamps do not have the light distribution problems like the Philips lamps, but striate slightly for a little while after startup. Again, not a big deal.

One of the benefits of the troffers is they help keep some of the heat in, which helps low mercury lamps produce full brightness.

My school has these in the library/media center, which was built circa-2000. The lamps are marked H0, made exactly one year before the one above, made in August 2000. Most in the library section where the books are are still working! However, the two computer labs with three-lamp parabolic troffers have lots of dead lamps that the custodians are too lazy to relamp. The fixtures all have the original tubes. The only fixtures they fix in the library are the 175W MH uplights, which I've never seen one out but some lamps are brighter than others, suggesting at some point the lamps have been spot-relamped (and there's no way a MH would last 16 years in regular use).

Sounds like the janitors are really lazy at your school, Mike. Mine has dead lamps too but much more far and few between. (And the maintenance guy is out of town for a few months). One room has more dead lamps than working, but the lights are waaaay up there and a PITA to relamp (the same Metalux/Gibson troffers I have; mine came out of building). Out of 12 fixtures, I think only three are now working, but it's almost still enough light...the classic "overlit so we don't have to relamp as much" setup.

Yeah it seems in my school, by the time enough dead lamps build up in the system, they do a lighting upgrade and just replace the fixtures lol.

It's funny how that works. On a whim last night, I googled my old elementatry school and learned they're modernizing the whole place (AKA remodel). I wonder if they're scrapping the already-converted-to-T8 lighting? Probably...(rolls eyes). Then we wonder why schools have funding issues (rolls eyes again)

Yeah public schools (and public/government run buildings in general) are the biggest wasters of money and resources. Think of how much paper could be saved by switching to online classes? Paper-and-pencil is necessary for certain classes but definitely not all classes! And some teachers give SO MANY handouts that my folder for their class is ready to explode! Like, is it REALLY necessary to give that many handouts? My english teacher has probably wasted 100 sheets of paper on each student (with ~90 students, that's in the ballpark of 9000 sheets of paper!)

I disagree on the online thing. I do some of my classes that way and HATE IT!
But they tend to waste resources...unless it's a small school district like mine. The building I go to high school in is original inside and out from '79 and '85 (different wings). All rapid start T12 too!
