Came in my slimline fixture I got today. These are picky about temperature- at about 40 degrees forget it but at 75 degrees they're pretty bright once warmed up but still flicker at first. Despite being the hated 60w energy savers (trust me, 75w lamps are in the offing) they're decently bright on the full-power Advance ballast.
Yeah only the good die young. Apparently that applies to lamps too lol. These dim purple lamps will probably keep going and going lol. Interestingly, the Sylvania 60W /CWX slimlines like this that I pulled from my grandpa's shop didn't have a ton of wear on them. There's one lamp that got gray rings as far as 6" from the end of the lamp though and it's been that way for years. I'm wondering if it's just dirt/spray redidue, as it's in the spray room. You can't see it most of the time since when he's got the garage-type door opened, it's blocked by the door.
no they were dead. He won't let me remove dim tubes if they work. Sometimes I'll still change them though since when the switch is off he doesn't know which ones work or not.
Yeah so it's brighter...
I like the Duro-Test Power-Twist Vita-Lite idea...giving it more phosphor area to make up for a dim high CRI lamp...I wish I could find a NOS case of those!
Although it was banned last month I like /765 too.
I'd like to get some daylight or /950 34 watt lamps someday...
Not 75CRI F32T8s until well...two months ago actually. As of July 15th I believe they can no longer be manufactured or imported.
I think low CRI would be allowed with more than 89LPW but I'm not positive.
The idea I think with the low-lumen 4100K CWX F40s nowadays is that they're technically specialty lamps and not mainstream cool white. Also their low light output will likely encourage people to convert to F32T8/841s instead. But I like my dim, inefficient /950 lamps on full power PCB ballasts!
Oh that sucks... I have a pair of SP35 GE EcoLux lamps that are over 3000 lumens a lamp and they're incredible lamps! I think 78 CRI. I think that CRi is plenty high.
It is kind of a shame...but it will encourage people to switch over to more efficient, modern technologies. I have nothing against the new electronic T8 stuff but enjoy collecting the old stuff for sure, as we all do!

3500K SPX35 T8s (/853) are really bright too!
