I've just fitted a pair of Wipac 8 inch spotlamps (they have 100w bulbs fitted as standard). When I turned them on for the first time I noticed the inside of the glass lens has somehow misted up so the lamps now have a foggy appearance. It's not water vapour so hasn't evaporated off. Hard to clean them as the only access to the inside of the glass is through the hole where the bulb fits. Anyone have any idea what caused this, and how to clean them? They're brand new but now look years old :(
