I have gutted a couple Philips lamps with an LBA202(?) SMT IC.
Little else of interesting components in such a lamp...
All the rest (far Eastern, as well as European made Osram and Sylvania)
using a couple transistors in a power oscillator circuit.
Of the several (must be more than twenty!) I have gutted the
electrolytic most often has failed. I changed it in one of the lamps,
which held more than six months afterwards.


It's funny, I'm always hearing about this problem but somehow I have yet to
ever run across a single one in which the lytic checked bad (ESR meter) or
blew, I know it's coming but so far never had that happen.
