Tried drying it out but it's misted up again already.
Guess there's nothing else for it but to take it out and change it![]()
Or reseal it. See my previous posts and others. Just drying it out is only addressing the effect, you need to fix the cause.
Take the light unit off. As described above check all seals and covers. Also check around where the lens seals to the body. If in doubt reseal with small amounts of sealant.
To properly dry it out, remove all bulbs, place lamp in airing cupboard overnight, bulb holes upwards. Refit the next day when warm and dry. If you've fixed the leaks, all should be well. Every expense spared.
