Have used over 6 of these bulbs in the past 6 months - all stopped working. Bathroom one went last night after it had its 'strobe' session, the bulb lasted nearly 2 weeks! The one in the dimmer lasted 10 seconds! The place looks like a 'disco inferno' when switching them all on. These were all Philips makes. They don't fit into the table lamps fittings. Wonder if they will bring out something for these. From the switching on of these bulbs and the flickering, they must be capable of bringing on an epileptic fit. Wonder if Gordon Brown has these in Checkers? Wonder if he liked disco in the 70s.
