I was pondering that thoroughly fascinating topic of what defines an electrical accessory as the term is used everywhere.
The best I could come up with was the below but wouldn't that imply wall lamps are not accessories as they consume current. So in turn wouldn't that mean a wall lamp does...
I removed a fuse and before reinserting did the following tests using test lamps. Live side - Neutral = 230V, Dead side - Neutral = 0V, Live side - Dead side = 0V.

We've all seen the LED 'curly element' style lamps in LED, but has anyone seen anything a bit like that in good old Tungsten still on the shelves anywhere? Need a bunch for a show.

I'm currently refitting a bedroom which has 3 double sockets and a 13 amp FCU (for a wall mounted TV). On inspection the wiring is as shown in the attached pic 'Existing'. Two sockets and the 13amp FCU are on the ring main but one is spurred from a traditional round junction box under the...
Hello, I have a fairly simple question like in the title of the post.
How to connect Two 9 watt UV lamps to a ballast probably electronic. I suppose electronic will be the best in my case, due to the built-in starter. I have read various sources of information but did not find my specific case...
Hi - I have a room lit by two undimmed strings of six x 4.5W MR16 no-brand non dim lamps. This system originally had 50W halogen MR16s and 2 x 300W torroidal transformers. Visually this was OK, but video flicker on a webcam was terrible with the LEDs (none in daylight or with a halogen lamp)...
