I've had several of these break when the lamp is inserted. Especially the ones moulded from bakelite. They are then useless and have to be replaced. It's only the UK that uses them, and I can see them being phased out before long. Much better to replace them with GES lampholders and fit GES lamps.
Jim Hawkins
Not quite true. The French use them too.
You mean ES. GES is enormous and was used fo 500w plus incandescent lamps in the UK.
There are problems with ES lampholders too. Don't buy el cheapo lampholders.
Bakelite hasn't been used for years.
er.... Giant Edison Screw - ?? really?!
Jim K
Goliath Edison Screen apparently (E39/E40)
see your wiki & raise you a Lyco
"GES (Giant/Goliath Edison Screw)."
;>)
Jim K
I expect the words you're looking for are 'imagine' and 'ES.'
ES holders have a few downsides over BC: bulbs more often jam in the socket bulbs sometimes unscrew themselves greater shock risk
NT
I stand corrected. Not 'GES' but E27 is the one I meant.
Jim Hawkins
I didn't know that. Any sign of their being phased out ?
Jim Hawkins
Except when you try to unscrew a dead bulb and the base is seized into the lampholder, and snaps off. If you're lucky it gouges you in the hand. If you're *really* lucky, the lampholder is wired "back to front" and the screw thread is live, too.
Hence the name. 'Bayonet' means 'burnt fingers' in French.

Maybe, when they reach their centenary - if they haven't already!
They've been around since before I was born - and I'm in my 70's. I don't see them disappearing any time soon.
The decent ones have metal linings anyway - which continue to hold the bulb even if the outer plastic breaks off round the bayonet slot.
The decent ones are metal. (IMHO)
I`ll put it down to cheapo production. Going back to my parents house they must have had bayonet sockets that lasted, well they were in that house for 40 years and never replaced one and thats with some sockets having 100w bulbs.
And us Aussies.

existing BC lampshades won't fit ES lampholders
If you buy the better quality ones they seem to have a metal bit inside as well as the plastic nice looking bit. the beauty of them in the old days of course was that the metal parts of the bulb were not connected to anything. However with new cooler running bulbs this won't happen, but their weight often puts a strain on the socket pins. Maybe there is a case for what you say from the safety point of view then, as les types will always remain potentially dangerous. Brian
I've also seen some with three pins on the side in some of those fire glow coal effect systems. Brian
They're a way to ensure that only (More expensive) energy saving bulbs can be fitted to comply with some rule or other. It's been mentioned here before as being de rigeur on new build houses.
