In the meantime, if you are consistently having light condensation in the lamps try this.
In most dry food goods, there is a small bag of desiccant (moisture absorbing beads packed in a paper bag). You can try to put that into the space between the reflector and housing to soak any offending moisture.
I used to do this with my foggy Lexus SC300 lamps, and it works well for a few months per bag.
Just be careful not too close to the light bulbs...
