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.

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

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??
