GE Polylux 36W/840

Here's a GE Polylux XLr, a European triphosphor cool white T8 lamp.

Curiously they're fitted with blue insulators, perhaps the very same insulators used intentionally on GE Reveal lamps exported from Hungary for the U.S. market.

Are these still manufactured in Hungary, or did they cease all linear fluorescent production?

Seeing this lit next to a T12- are you successfully lighting it on rapid start?

No, they are not made in Hungary anymore.

May all the great lighting technologies have their place in history.

@Andy I got my Philips TLD36W/965 lamps to operate on rapid start, but it was next to impossible. Had to warm them up first, then place one with a warm T12 on the same ballast. Worked, but flickered too much. The cathodes don't like continuous heating apparently.

This fixture has a preheat ballast. I've only lit one on two-lamp rapid start with a plasma ball. They start better on a single-lamp rapid start ballast, though not without difficulty. On one of my single-lamp ballasts, 36W lamps act normal once lit, while the other will first strobe, then shimmer until the lamp warms up. I believe this is due to the lamp extinguishing for a prolonged period each cycle, on account of the higher voltage required in order to sustain an arc. However, once warmed up they operate fine on both RS ballasts.

Maybe try one on an Advance PowrKut ballast such as this . They turn off power to the cathodes once the lamps strike.

Don't be fooLED, T8 IS the worst thing to do to a magnetic T12 fixture.
