Sylvania Lynx 23w 1st gen magnetically ballasted CFL lamp

After finding some 14w version of this lamp a few years ago, I recently came across this larger (or should I say longer!) 23w variant, equivalent to a 100w GLS lamp. This lamp has a near-instant start (accompanied by a nice starter "ping") and as is to be expected, is very heavy. These lamps were ditched in favour of the ubiquitous Lynx-EL CFL only a year or two after they were first released, and needless to say, they were poor sellers - making them rather rare these days.
