It's an urban legend that bulb life of halogen lamps is shortened by
finger oil. The surface of the bulb may degrade somewhat where dirt
and oil react with the quartz; but that doesn't affect bulb life only
the appearance of the bulb.

I do not believe this "urban legend" claim;can you provide any proof?

It's not that dirt or oil react with the quartz,it's that they carbonize
and create hot spots,and then absorb more heat.
