  • My bathroom is currently lit by three 12V MR16 halogen downlights, each with its own transformer. Two of these keep blowing bulbs. I've checked that all the connections are screwed down properly and replaced the lampholders (because I understand that the heat from the lamps can weaken the springiness of the contacts leading to a dodgy connection to the bulb), but it's not improved things. I may have also replaced some of the transformers before (although I cant remember for sure).

    What do?! Replace the transformers again or switch to mains-voltage, IP65-rated LED lamps. If the latter, is there anything I need to check before doing so and does anyone have a recommendation for a particular LED lamp?

  • I had the same. Bulb and transformer blowing and or burning out. A bit worrying as there is circa 20cm of loft insulation above, seemed like a fire hazard to me.

    We paid £120 for a sparky to replace all three with Led, that was labour plus parts.

    Very pleased.
