That might be IS. I've seen that starved bulb look at work too. Just as dim. LOL!

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.

I'm thinking it might be trigger start too. Those electrode filaments are heating. But it should have trouble starting on trigger
start ballasts as well, I would think. Maybe this lamp has been operating since the first day it was installed, back when there
was no signs of mercury starvation.

I've seen in the past mercury starved fluorescent lamps on preheat/switchstart ballast, that had their cathodes glowing visible.

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.

I've seen preheat lamps do this as well. There's a good chance it could be preheat... I had a PL 9 watt lamp
that went mercury starved, but this was way back when I was a kid. One of the first desk lamps I've ever bought. At times it
lit successfully, but this being after several failed attempts at lighting. Maybe that is what's happening here

这样启动器一直卡住工作的话,长时间不更换启动器,灯管很快就会结束寿命,我初中时在学校就见过这样一个例子,当时一个班里的灯有个不启动,然后一直没人维护,等我期末考试去他们班时,发现灯管黑头已经相当严重了,因为当时才用了不到一个月,到最后灯管烧了,镇流器也烧了,直接换的整套灯具,那套灯的使用时间不到一年就整体报废了,可见其危害的严重性!

This starter has been stuck in the work, the long time does not replace the starter, the lamp will soon end the life in school, junior high school when I have seen such an example, when a class is not a lamp to start, and has no one to maintain, so I went to the final exam in their class, have found lamp black quite serious, because at that time it took less than a month, until the last lamp burned, ballast also burned, the whole lamp directly changed, the lamp is used for less than a year as a whole was scrapped, visible the serious harm!

我不会英文,所以我用中文,请你们用翻译网站翻译我打的字!

I can't in English, so I in Chinese, please use the translation website to translate my words!

@men of god
The starter is not the cause of problem in this case. The lamp is running without Mercury, what you can see here is the buffer gas glowing.

No more cheapy crappy Chinese junk, please.

Yeah, you're right! Also I see one that is very similar to that: HE F60T10/cw 135 watts that glows purple...it's in Las Vegas The Orleans located by Baskin 31 Robbins...if it's still there when you went there!

There is current through the filament from one of the wires (or both in shorted sockets) up to the point where it exits from the filament into the discharge. The point of exit is in contact with the concentrated root of the arc so that is the most heated spot, it glows always - this glow is simply hidden by the main light output in an intact lamp

I have one of those fixtures it's a GE home electric product there is no model number that I could find. The starter on mine is located inside the fixture and there are little plastic clip thingies that allow the ballast cover to come off.
