GU10 LED on 12V DC

MikeDIY · Jun 18, 2020

I have garden LED light running fine through a transformer..

LED Driver Adapter AC 220 -240V To DC 12V Transformer

But am now trying to add a new downlight with a GU10 LED bulb, however the bulbs are not lighting, looking at the bulb box it asks for 220-240 AC

I am struggling to find a GU10 bulb that seems like it will work on 12v DC, but none of the bulbs I'm finding are mentioning Volts, just Wattage. It does not make sense to me, which bulb do I need?...

As far as I know all GU10 LED lamps work on mains voltage only, GU10 light fittings are designed to be connected to mains voltage.

GU10 lamps are 230v.
GX5.3 lamps are 12v.

Ok thanks, is there not something I can do to make this work?

I could try moving the transformer to run only the 12v LED lights and let full 230 to go to this light, only reason I didn't do that in the first place is that someone told me its not a good idea to run full power down the garden

You'll need 230v to make GU10's work, there is no reason why garden lighting cant be mains voltage but it must be done properly, and must be 30ma RCD protected.
