Since this is starting to be my own personal posting board...
Lightbulbs. Bayonet light bulbs. Ok, so I get how they plug in. I just had one blow out (overhead). Took the circuitbreaker. Fixed the circuit breaker. Now need to replace the bulb. My options are to toodle to the nearest shop, which is going to be the grocery store at this time of day where I'll be grossly overcharged for said lightbulb, or order online. Since I don't really want to have to take a bus to B&Q for a lightbulb if I can avoid it, online is appealing.
There are no visible markings on this bulb, other than it's a 240v bulb. Trying to figure out what the "standard" bulb size here is. (Have checked all the other overhead lights here and they all seem to be the same bulb, and none of them have any size writtin on them.) By any chance would that standard be a "B-22" bulb? If so, I can try to order a LED replacement bulb in that size.
