I bought a 50w mh ballast kit since it was a great deal, and we'll see if it makes it into my country. Honestly the fact that this is even a concern is very disappointing.

It'd be very helpful if there was a detailed guideline list by ebay I could read to know which lamps and gear I apparently don't have the right to own anymore.

If anyone finds an official guideline list about this lamp ban by ebay, post it as a new topic and I'll pin it to the relevant forum board, so that members can access it, and help them decide if they should chance a potential purchase.

 I just bought one of the clear Halarcs !

I'm after one of each.

 Talk to the seller/LG member , Maybe you can work out a really nice deal !!

Cool lamps! Its nice to see HID lamps with their own type of personal ballast.

Ours have just arrived, thanks Patrick 

Detailed guts photo, anyone? There was a lamp with a broken ballast filament, nothing to lose by opening it...

I gave that one away to Alights, so he'll need to decide whether to disassemble it or keep it intact.  We do at least have a photo from James and a photo from DimBulb of a transparent prototype.

There are also two groups of photos on Smithsonian. https://americanhistory.si.edu/collections/nmah_1301514 and https://americanhistory.si.edu/collections/nmah_751254

First one look like some rough prototype, but has a straight image of board conductors, albeit in very poor quality.


My goal is to try to build a clone of Halarc ballast for fun. Hard to get a proper DC lamp, but I suspect a regular modern cheap Chinese NaSc lamp of Venture style will work on DC at least for some time.  Schematics looks rather simple. I can ID a classic looking ignition transformer, some diodes (may be also ignition SIDAC), one single small plastic transistor or SCR in TO92 case, a larger transistor or SCR in TO220 on that prototype board, a large electrolytic of 50uF, couple of power resistors, some small capacitors, and one or two thermal fuses.

By the way, what happened with James' Lamptech site today??

 

@ RRK:
Thanks to Tim, we have two of the DC lamps, one cap up and one cap down. 

And where are the pictures?

Here they are: base up and base down versions
