Lightbulb ID please?

[KT_UK]

Hi, this might be a dumb question but I need to know what lightbulb type this one is.

Is it different from MR16? The pins are similarly spaced to those of MR16 (on the right in pic 1) also the shape’s flatter than MR16.

Thanks in advance.

MR16 is the size of the multifaceted reflector (16 eights of an inch) and nothing to do with the base. MR16's come in GU10, GU5.3, small bayonet and small ES.
The lamp on the right is a GU5.3 the size is MR16. The lamp holder on the left is a GU5.3.
What you plugged into it is something unusual. Difficult to tell without a scale.

Thanks for your reply and explanation.

Yes I don’t know anything about lightbulbs... have googled and asked around, now with all of our hallway lights completely gone, I came across with this forum and decided to ask for help...

The lamp is a CFL. Basically a fluorescent lamp. These were the early generation of low energy lighting. They have gone out of fashion because they take a time to come to full brightness, hard to dim and the light output is not that nice.

Personally I would chuck the old ones out and install new fittings.

LED is the way forward. Is there any writing on the old lamp to indicate voltage, etc?

Almost certainly will have a ballast / driver unit in the ceiling on the end of those 2 black wires.
Should be a manufacturer / model number on that.

Chances of buying a replacement lamp are pretty much zero, and they are likely to be ridiculously expensive even if one was found - but it would be interesting to find out who actually made it and when.

Thanks or your reply.

We moved in 10years ago and never had to replace any of the bulbs until now. Sounds like we’d better get new fittings!

Not sure what to look for on the lamp... it says ‘ROHS MR16-7w 4000k’. Any good?

That explains why I’ve been unable to find identical replacement bulbs... Will go up on the ladder and have a look tomorrow as our hallway is very dark now!!

Rohs Just means it complies with certain regs for Hazardous substances if any that are in the lamp.
Mr16 is the sort of shape 50 mm diameter
7W is the wattage
4000k is the colour

Could there be a lampholder under that plastic cover, most CFL lamps were mains voltage GU10, that connecter may be just a joiner in the mains cable
