For those collectors with this version of the gs, i am about to revive this project as i have found a local company who could highly polish or re silver the reflective part. Its likely if used regularly they are now pretty dull, and not giving its full potential light output, i have the derann original xenon's, and are due to be replaced, although one is worse than the other. Once replaced, the lamp if your keeping it will need aligning to the new reflector once in place. Not 100% sure the reflector will come out with out a major dismantle, perhaps someone knows or has done it ?, please add a comment. Obviously the more people who show an interest, i have more bargaining power with the company, either way i will be getting mine done...............
