LED Driver - replacement for G4 halogen spots in kitchen

[maturin23]

Hi all,

We've currently using G4 halogen spots (IKEA Grundtal) for under cabinet-lighting.

The bulbs run hot and don't last long. I'd like to replace them with 1.4W LED equivalents, using the same light fittings.

As far as I can see I need to replace the 240v-12vAC transformers which are sat inside the wall cavity with 12vDC equivalents.

The lights are in two sets of three and one set of six so I'll need three transformers. Don't need to be dimmers.


Can anyone recommend the max wattage for these? Any brand recommendations for transformers and LED G4 lights would be good too.

Thanks - that looks to be for dimmable LEDs - I just need ones that are either on or off!

Hi guys

I spent the weekend re-skinning the kitchen which also involved swapping the G4 halogen downlights for LED bulbs.

I replaced the existing 12V AC transformers with these -

and the 10W halogen bulbs with these

All very straightforward and so far work a treat. At least as bright as the halogens.

One question I have is that as the transformer only has a single output and I needed to run three off each (due to location) I made a three to one splice (twisted, soldered then applied heat shrink) which is robust and safe but a little crude.

I'm putting another set in this weekend - this is a run of 6 LED bulbs. Can anyone suggest a compact screw-terminal junction box that will allow me to connect the six output wires to the single output of the transformer in a neat and tidy fashion?

Many thanks
Ian

See my link above - they replaced my G4 halogens perfectly - no bigger than the top joint of my index finger.
Only £0.89 each too.

a BT 77B would work.

Isn't that for telephone wiring?

Will be running 6 x 2W bulbs so not exactly high power stuff, but as it's sat inside the kitchen wall cavity I'd like to be sure.

Nah, I know the G10 types but these are the G4 bulbs, like little capsules. I'll measure one of the halogen ones in mm and see if I can find any LED ones of a similar size. It's not a big issue just disappointed 'cos i thought I'd hit on a good idea.

Seriously - you join in a thread I started about replacing G4 halogens with LEDs and then completely ignore my subsequent comments about successfully doing this?!

You'll have to try a little harder than that!

Excellent - hope they fit.
My ikea spotlights are pretty small and they squeezed in no problem.

Is your 12v output transformer definitely DC?
