EYE Sunlux Ace HPS retrofit lamp

This is an early-style HPS retrofit lamp by EYE. Rather than the traditional Penning (neon-argon) fill, it uses the xenon fill of standard HPS lamps. The new EYE lamps use Iwasaki's patented ferroelectric (FEC) ignitor, but this version uses a series of incandescent filaments and bi-metal switch instead. They heat the arc tube end to facilitate ignition - it starts much like a preheat fluorescent. Here is a short video of the start up and restrike on my 250w metal halide ballast. Total measured power consumption is 222w versus 267 using a 250w metal halide lamp, so it is a slight savings, and produces higher lumens.

The interruption of the bimetal switch create there high voltage kick, what then ignite the lamp.

No more selfballasted c***

If this lamp uses a thermal starter to start the lamp, then why in the video, the hot restrike looks like it is looks? Is the lamp hot restrikes directly from the mains without the bi-metal?

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 (

Because a small discharge happened to strike in it as soon as the power returned, so it started from this discharge without waiting for the bimetal switch

This can sometimes happen with a SON 70w with internal ignitor too
