Zohan. There is a really easy solution for eliminating condesation that forms inside 'sealed' fixtures. (This ocurs when you open the fixture to install the lamp in humid conditions, then you close the fixture, trapping the humid air. Later the ambient temperatures decrease and the moisture condenses out of the air and onto the interior fixture surfaces.) I am a bit tired of 'giving away' my secrets on this forum and seeing my local competition benefit from my experience, so drop me a private message and I will tell you how to solve this. Regards.
