Installing led downlights

Hi all

I have a query about led down lights. I am installing 6 in my dining room ceiling and a further 6 in my kitchen. Does each LED require its own transformer or is a single transformer sufficient for all 12 lights.

Just get 230 volt ones, no transformers required.

I agree with the above answers, transformers are not needed unless they are low voltage. 230v/240v downlights are available at wickes, screwfix etc.

As already said better install GU10 downllight, that works on 240v, GU10 Led lamp will have a mini transformer incorporated.

Responding to your question You can have one "large" transformer feeding all of them or a single transformer feeding each one , all is about your choice.

Depends on where you want the Led lights fitting?
If in a bathroom with older wiring with no cpc then you will have to go with IP rated Led fittings double insulated mains voltage or 12v drivers which will be ok as the safety requirement will be SELV (safety extra low voltage )

Hi there, depending on the style of LEDs your installing depends on what is required. Say if using GU10 LEDs, which have the driver in-built so no transformers are required. Or using MR16 LEDs, transformers aren’t recommended, LED drivers are! as they give the LED more control and more stable to flickering. Try to avoid using transformers that were originally supplying halogen lamps.
Hope this helps.

Hi, unless the downlights are low voltage there is no need for any transformers. Modern day downlights run at the standard 240v, they are simply low energy because of the led lamps.
