Massive eol powergroove show

Massive eol powergroove show

Click to view full size image

I got a bunch of used newer powergrooves (the ones with missing grooves and meatball etch) I ran this particular pair all winter all day every day but since it warmed up now it's time has come. It wont quite die like a t8 tends to melt a hole or crack it just keeps on flickering and swirling then shuts down then back again. I'm pulling it out I'm getting worried about the ballast time for the Dumpster or keep around just to show off to some other lighting enthusiasts.

The automatic resetting thermal protector is kicking into gear? Or do you mean it shuts down to a dim flicker?
I personally rarely ever see Rapid Start ballasts of any kind, have over heating issues during EOL shows lol, unlike Slimline ballasts.

3. Severe Thunderstorms of all kinds
4. Food and drinks. So gimme them bbq ribs
Yep
Lighting has been a passion of mine since I was born. I consider everyone on LG to be a friend

Funny how you say that. The lights in my Uncle's kitchen DON'T have working thermal protectors (sadly found that out ), but the F40T12 RS shoplight in my uncle's garage shuts down after running a couple of hours straight.

It just dims down then fires up again

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

When the thermal protection of the ballast trips, this disconnects the ballast from the supply, which means that there is no current in the lamp, so it should be completely dark. Dimming to a dim flickering meaning something different (This lamp looks like it about to lose vacuum).

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.

It doesn't get to that point its dims down and swirling appears then back to this flair up. It seems the t17 allows it to cool enough to not let it loose vaccuum

I had two already EOL tubes hooked up on our Knobel 218-4000 magnetit RS ballast, they instantly started to glow orange at the end, the electrode supports were melting down until the stem cracked, then the tubes lost vacuum. Monkeyface was with me watching it, one tube had lost vacuum already after 10 seconds, the other was struggling for 2 minutes.

There is a video in my gallery.

Yeah from what I know, HO and VHO EOL's can be rather impressive... although I've never seen a VHO reach EOL yet,
other than in videos. It depends on ballast OCV normally... although I've seen impressive EOL shows from even the low
OCV Rapid Start ballasts. (HPF F40T12 R.S ballasts.)

I never tired of watching EOL shows on linear fluorescents! Even standard magnetic rapid start gives a show if the emitter goes while the lamp is lit before it resigns to dim-flickering.

@ace100w120v, yep I've seen many EOL shows that were impressive with standard magnetic rapid start ballasts... at least the HPF ones.
Some of which ended with vacuum loss. Rapid Start EOL is and always has been awesome to me. The first EOL I've ever seen in my life was
in 2nd grade, and it was Rapid Start. It was very entertaining, but it scared the crap out of me since I had never seen a fluorescent lamp
burn out before. And of course, as a 2nd grader, I thought that lamp was gonna explode since I saw the brilliant orange flashing.

My old middle/high school was at one time primarily fitted with the '90s-'00s GE 34w Watt-Misers with the long electrode stems. Those would be entertaining EOL-show-wise, even on standard HPF magnetic RS.

The majority of EOL shows I got to see, ended up being in elementary school. Literally every EOL I've seen took place at that school were all
Sylvania F40T12 cool white lamps. My middle school got the drop ceilings/2 lamp electronic F32T8 troffers by the time I got there, so no
EOL shows there really, but at my high school, I did get to see one GE F34T12 lamp reach EOL, right when class ended.
Man I miss those days.
