¡Hola!

I need some help finding what these bulbs are called. I’ve tried typing all of the numbers I can see on them into Amazon, but none of them are working, and I don’t think they are rare because I am sure I have seen a bulb like this before.

I know I could go and match them at B&Q but I’d like to order them online because I am tired and it is raining. I’d like to get them in a warm white :bulb:

Thank you so much, Davpaz :luv:

I’ve just typed that into Amazon and every listing says GU10 despite me typing GU20. Was yours a typo or are they two different things?

Are you sure, they look a lot like the GU10s I bought a while back?

I call these Frankenstein bulbs as they look the bolts in Frankenstein's Monster's neck (as opposed to the similar, but not compatible spikey variety which for some reason my house has both! Another reason to hate my electrician from 17 years ago)

It's depends on the distance between the prongy boys

Can you measure, Mimi?

The prongy boys! :DD

The bulbs are for my light fitting at work

ZOMG Spoiler! Click here to view!

the current bulbs work fine but they are a really cold light, and it feels clinical and depressing when they are on

and I’m back home now, but I’ll measure the gap between the prongy boys on Monday. Thanks guys

AFter further digging, the gu20 is much rarer. Odds are they're GU10

Super. I’ll likely wait until Monday anyway as there is no immediate rush, and I’m too lazy to return them if I get the wrong ones

They were GU10s

I got a set of six warm Phillips GU10s for £9 and they are just SO much better.

Thanks for the identification help, folks!
