Electrolytic capacitors. They kill most consumer electronics.

I'd tend to agree. I had one fitting with a replaceable 'rectangularish' tube.
When I replaced the tube, it didn't last much longer.
Of course you can buy them with many estimated lifespans. I've seen 3,000 6,000
10,000 12,000 and 15.000 hrs. Needless to say, the price varies.
I've generally found Philips to be pretty OK and OSRAM ( Sylvania in the US IIRC
) the best for reliability and long life.

Lets see if that URL stays together. If not, it's Shop lights
(fluorescent) and the extreme unreliability of the cheaper ones.

I've rarely bought cheaper brands, maybe on only 2 occasions. So far no problems
but they're not in situations where they're highly used.
Otherwise I stick to Philips and OSRAM / Sylvania.

A certain consumer guru (http://clarkhoward.com ) says CFL's are a
stopgap and the Next Big "Green" Thing will be LED lamps which last
NUCH longer (maybe they'll socket the electrolytics) and not have any
mercury or other bad substance that escapes when breaking. Dunno if I
believe LED's will take over, new things usually do go down in price
and up in volume, eventually upsetting older technology, but it
doesn't always work out that way.
