Water droplets on downlights in bathroom

    We've just got our bathroom redone. The job is finished and I noticed that after a shower, droplets of water form on the chrome ring of the downlights (not on the bulb itself) and won't go unless wiped off.

    Bathroom has a slopped ceiling.
    Bathroom has been insulated:
    80mm warm boards on external wall
    50mm of Extratherm boards between the joists with 30mm warm boards on top of the joists.

    Downlights are on the slopped ceiling and to fit them (and to leave space for the bulb) a hole the size of the downlight has been made all the way through the insulation.

    So basically each downlight is a cold spot. Whilst we have an good extractor fan fitted (good as in after a shower very little if not all visible steam is gone) condensation is forming on the downlights because they are cold.

    Ideally we would have like to have some insulation above the lights but the joists are only 100mm deep so I can't see how this could have been done - correct me if I'm wrong.

    If we have to live with the cold spots is there any solutions to prevent the droplets forming? Could I apply some hydrophobic coating on them?

    Thanks for any suggestions.

    Have you access above the downlighters?

    If so, put flower pots over them and insulate over then to keep them in the warm zone.

    Works even better if you are using LEDs as they wont overheat.

    Lights are 4W LEDs but no access above downlights.

    Could you spray foam into the hole? re-fit the light with a plastic bag on top?

    Spraying foam into the hole is an option. Not sure that's really safe though. Lights are only 4W but I'm sure they require some sort of clearance?

    Are they sealed / fire ratted down lights? Sounds like they are being cooled from above.

    They are not sealed. And yes they are cooled from above since there is no insulation above them.
