A US Philips ALTO F96T12 110W HO lamp wildly flickering on a rapidstart ballast « on: May 21, 2010, 06:07:59 AM » Author: dor123

This lamp is found at a supermarket near Rosh Pina township.
This is not a smooth 50hz flicker. This is likely that the ballast trys to reignite the lamp to stablize it (EOL behavior).
As you can see, there is NO end blackening, so why it is behave like it's reaches EOL?
Note: The flickering was much more wildly in reality then in this video.
The ballast is Eltam's rapidstart magnetic ballast for 105W T12 lamps.

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 international date format (dd.mm.yyyy).

I lives in Israel, which is a 220-240V, 50hz country.

Early rectifying is possible, if one filament is dipped in too little emitter during manufacture.
