Which G4 LED bub type do I require?

[cordless]

Hello all,

I want to purchase some LED G4 bulbs for my under counter lights.
I need to know whether I need 12v or 230v, and whether i need AC or DC.

Here is a phot of my transformer:

edit:- dont put LED's on a normal transformer, they wont last long. Whichever wholesalers you buy the LED's from, ask them for the correct Driver for them.

Fantastic, thanks for informing me

Ill get a couple of these:

Unless I can run two bulbs (3w each) from one transformer?
