15W filament lamp controlled by a tiny reed relay, on for a total of a
couple of hours a day. Been in use for 20 years or so. Decided to replace
the working 15 filament one with a 11W CFL but on first switch on, the
contacts ,presumably only 0.5A rating or so, held on at switch off.

A slight tap releases them but of course no good with continued CFL use
unless uprating the relay. Previously stuck contacts occured 10 years or so
back when the first 15W bulb blew, plasma arc current at failing switch-on
presumably.

What is the switch on current of CFLs compared to conventional just out of
interest ?
