I have two ceiling light fittings in the living room fed from a dual dimmer wall plate which also push for an on/off switch. I habitually turn these on by pressing both switches at the same time; did that today and both bulbs blew as they switched on, the bulbs are from different manufs, of different ages. So what are the odds on that happening?
Annoyingly that's two of my dwindling supply of 100W incandescent bulbs gone.
