I believe they do. Maybe the step down transformer
does a lot to reduce turn on current at phase peak
due to it's inductance, and probably reduces startup
current quite a bit due to saturation limits of its
core and windings. I've never used them, but friends
have and I have never heard mention of short bulb
life. :o)
