Low voltage LED problem.

    I recently bought some 12v 1.8w LED bulbs to replace 30w halogen ones, they all worked fine on some of the transformers, not at all on others, and on one, gave just a flicker of light.


    Any idea what could be going on?

    Hi Henry,

    Thanks for your post.

    Unfortunately 12 Volt LED light bulbs are not always compatible with existing low voltage transformers. 

    In this case we would recommend getting an electrical contractor to remove the transformers completely, replace the 12volt (GU5.3) lamp holders with GU10 versions and fit good quality GU10 LEDS, such as this one from our online store. 

    If you have any other questions please don't hesitate to ask.

    Regards,
    David

    Its due to not meeting minimum load, so you could change to higher wattage lamps or use an led driver instead of the transformer but for the long term using Gu10 led is a much better option as David already pointed out.

    You need Max-Led LED transformer 0-50W ETZ (If the bulbs are AC/DC) or Modular power supply if the bulbs are only DC.

    Thanks, I thought ohm's law might come into play alright, funny how some can manage it but others can't. I'll just put in some low voltage loops coz I'm not pulling the whole ceiling down.
