Older Sylvania bulb with interesting starting aid, unknown date of manufacture

Any help in dating this lamp would be appreciated, I have uploaded another photo showing the interesting wire wrapped around the arc tube, presumably to aid in starting the lamp.

The only date code is '14' written below the lamp information.

Forgot to add, interestingly the bulb takes a while to warm up and doesn't quite reach the usual 'orangey' colour of HPS, but is more in between a SON bulb and CMH bulb. Im guessing this is due to a high amount of mercury?

It is not a very old type. Most probably from early 2000s

This is a high output high xenon pressure HPS lamp, which have a higher ignition voltage, and the capacitive coupled wire is here to allow the use of standard 4-5KV ignitors.
The lamp looks like it leaking.

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 like it when they take a while to warm up, is it sort of a pinkey reddish colour?

Yeah, it starts off and stays on a blueish mercury colour for a a while, then eventually reaches a pinky colour.
