Bayonet vs screw bulbs

[Spark plug]

With screw fittings you also run the risk of removing the glass and leaving the cap behind, especially with outside fittings.

I have a mix of bayonet and ES in the house but as i do a room i change to ES pendants but the ikea ones are rubbish the cover where it fits to the ceiling never fits well.

On screw fittings the bulbs never sit straight in the holder either, they're always cocked off to one side, annoying if it's a nice fitting with a bulb on show.

After some time the tab at the bottom bends down and looses contact with the bulb meaning it needs bending back up.

How long ago were screw fittings the standard in the UK? I was always of the understanding that bayonet was the british standard, I have some very very old B22 fittings in a box, from when you used to plug appliances into the light fitting. I though it was the EU that brought in all this screw fitting rubbish.

In photo / TV and stage lighting it has always been a screw fitting. As the lamp doesn't move as it heats up.

Cheap gear will cause you problems like anything else in life.

I much prefer bayonet fit. Hate the screw type. Hate the way it is called Edison screw - when Joseph Swan invented the bulb ggrrrr

 

[Olderisbetter]

lets just call it the Swan Screw fitting.. actually that sounds a bit odd... and why is it they normally use your surname to define you by when you invent something? In the case of Dick Fosbury i prefer to have the Fosbury flop, at my age Fosbury flop is a lot better than using his first name.

 

[mtt.tr]

Depends on were its made, bayonet is preferred as its a little safer and cant be wire wrong

But most of the world uses screw so for them its cheaper to use one fitting

Worth noting that the US has always only been ES/SES.

Out of interest, does anyone know if it was only the UK that brought in Bayonet cap?

It's still a fairly common fitment in Commonwealth countries, as I found when I was looking for some old-style adapters (the ones my granny used to plug her iron in to).
Place to find them was Singapore, iirc.

its a right pita now the house used to be entirely BC fitting with the exception of the fridge that was SES

now at a time were everthing is soposed to be standardised we have some how managed to have SBC, BC, ES, SES that now means according to sods law we've got a full cubard full of lamps and you can garantee never got the right one

I found you one a bit closer.

we are migrating over to LED but had quite a few problems with them tbh lights with multipul lams really do like to start flickering

 

[ukracer]

you will find pendants in houses are still bayonet and all bulbs available but pre wired fittings are mainly ses small Edison screw

What's the best bang for buck to light a 6 metres X 5 metre conservatory in terms of led lighting. It's got a polycarbonate roof so it's light during the day but horrible at night....it's also Cold but that's another thread. Lol

 

[brightspark]

pretty limited .if it has a beams across you could put track lighting in using gu10 led spot lamps on it

Fluorescents no good then?

But yes it has one 14 inch by 5 inch wooden beam across. The aluminium roof bars run longways and can't be screwed to. Two walls have a feed to existing lights that are currently more ornamental than useful.

Ah, yes, now somebody's started importing them.
I was looking for one in 2006, and none were to be found, except as I mentioned.
I ended up taking a punt on some 'collectible' pieces, which were perfectly functional.

if you use 2 of these it will light the whole lot up

im finding theres a difference between the watts 15w equals 100w but i have 10w equals 100w

the 15w equals about 120-150 watt bulb but the 10w equals 80 watt bulb

I was a bit surprised to find a mix of ES and Bayonet when we moved here. Shops sell both, inc Brico Depot aka B&Q

They haven't been screw for a long time (That's my job funnily enough) all push in pins or clamp holders for pins. Most common 2kw up is the GX38 and below 2kw the GX9.5. you can still get the older P28s but they are a bayonet style holder.

I do have a very old 500w e27 bulb in my box of old bulbs though, along with a twin filament GX38q based lamp, which got swapped out for a GX38 as the replacement lamp cost was getting silly.

Of course it's all going LED now.

Without the bayonet cap, this album cover would not have been possible

Also Spanish customs might have gone easier on Andy Earl after thinking he was mad fro bringing hundreds of non screw cap lamps over.

Because they were in the same room the fire started.

Screw in's of all sizes are notorious for being welded on to the side contact so when you try and unscrew them , When I lived in Germany for the best part of 9 years , fairly often you'd twist the bulb out the ceramic cement mounting leaving the wires twisted . Then it's a bit of a job to get some long nosed pliers to try and free the remainder of the bulb base from the fitting . Same with lamp stands & bed side lights . That's why I like the GU and G terminations that said even the GU pins sliding contact bulbs can fuse to the power strips resulting in you shattering the ceramic holder & having to replace the whole holder or sometime the complete light fitting .
