Replace Halogen Downlights with LED Lamp Tips:
Buy the highest wattage LED lamp you can find or afford. Usual wattage for LED should be 5w and above to get a nice bright light similar to halogens.
If you have dimmer make sure you buy a dim-able LED otherwise they won’t work or will flicker.
Some MR16 LED lamps won’t work with the old-style iron core transformers that would be inside your roof space. If you find that your 12v transformers don’t power up your LED lamps you will have to get them replaced by an electrician
