I always thought that the once-ubiquitous F40 Tulamp preheat ballasts were made until 2010 when the DOE regulations took effect. On the other hand, I don't think I've seen such a ballast made after the early 90s. Not that it made sense for anyone to produce them after around the 60s, when RS became the big thing.

Advance doesn't list a 2x40 preheat ballast in their 2002 catalog. I couldn't find any info when I googled the BRSH-240 (or when I added -TP at the end). I don't know if they ever made an LPF version, but the name of such a theoretical ballast would have probably been L-240F-TP, and I found nothing when I googled that either.

The most recent tulamp preheat ballast I've seen on here is John's Universal 205-TC-P from May 2004. I heard they were made until 2005 when the first of the DOE regulations came in effect. Non replacement RS ballasts (the ones with full length leads) were also banned in 2005.

I too would have thought production of these would have stopped ages ago.

I have four GE bonus line Tulamp style ballasts that were made in 1988. I didn't know that they made them that late either.
