Lamp Holder

[Pete10001]

Happy Sunday to you, I was helping my Son out the other week, Yes before anyone asks he is an Electrician and so was I  I'm retired now, he had a customer call to say he had replaced some switches in his home and the lights no longer work. I'm sure you have all been there, after checking we found he had screwed up the switching arrangements, no big deal easily sorted. Except one fitting, a bog standard pendant had a dud lamp, unplugged the lamp to find it had three prongs instead of the usual two on a BC lamp, can anyone  throw any light (excuse the pun) on this?

Sounds like a bog standard  crabtree low energy LH to me.....common on new builds a few years ago to comply with the obvious regulations....could be Part L or any other letter that you choose

just saying

I've seen the PL and the GU10 type LE lamp holders,,, but I've not yet seen one with 3 alignment lugs... But a quick Google and hey guess what I found

Pray tell, Oh wise one.....what did you find?

i've found some weird stuff with Google

just saying

There is a new estate near me where all the new builds had to be fitted with these three pin type pendants with energy efficient lamps to meet local building requirements. The three pin arrangement was to stop non-energy lamps ( standard 100w style lamps) being installed, obviously the light from the ef lamps is rubbish and I did ok from going around afterwards replacing them with the more usual two pin style pendants....

never seen the 3 pin ones, but changed many CFL pendant holders to normal BC type

You can still buy 3-pin bulbs for electric fires, which were standard a few years ago.

which means 3-pin lamp holders were available , so it was easy for manufacturers to design low energy lamps, etc, for an existing 3-pin lamp holder.

Yup the 3 pin MEM ones were 13 Watt CFLs I think.  As Part L no longer requires special Low energy lamp holders just change the pendant to the usual BC

I think they were Sunhouse

there was also an even rarer lampholder with 2 sockets to take the 2 PINS on the fireglow lamp , like a great big MR16

dont get me wrong
