This is a twinarc HPS lamp with two arctubes connected in parallel, in which only one arctube operates, and in the case of power interruption, the operating arctube shut off and the second arctube strikes instead, allowing shorter hot restrike time.

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.

What's the point of telling us what these are? A good 90% plus of posters here already know this.

Assuming your figures are correct (source, please..?) that leaves 10% who after reading this, now do.

To be fair, I didn't really know how these worked either.

Any machine is a smoke machine if you operate it wrong enough.

I'm guessing these last longer than the single arc tube types ...

I think they probably do. On a cold start either tube could strike, so it's a 50/50 chance which one you'll get. On a hot restrike the other tube will strike, so again it's likely that both tubes will get roughly equal wear. I don't have any of this type of lamp so I can't speak from experience, but it seems logical.

Yep... rated at some crazy 80,000 hours or something like that.

Sorry...I just get flustered with dor123 running off all the time. He'll make comments without reading the whole lamp data...he's done this to many uploads.

These have been discussed several times on here...so I thought the 'old timers' already knew this.

They are rated at 40,000 hrs. (One arctube is rated at the typical 24,000 hrs, while the other is de-rated due to radiation exposure from the working arctube. Typically, one arctube becomes primary, while the secondary will only light in a brief power outage, or when the primary arctube fails. This is based on personal observation.)

Perhaps a thin foil strip between the arctubes would increase the lifespan. Also I don't see an issue with dor's comments he's not harming anything.... Perhaps I'm missing something...

They possibly do, but there are newcomers as well, so it never hurts to explain.
