Why Can't You Touch a Halogen Bulb?

Answer

We shouldn't touch halogen bulbs because of the grease and salts from our skin that ends up being deposited on the quartz surface. This damages the bulb because the formation of 'hot spots', which are created when the light bulb is on, results in warping and stretching. This is called carbonization, and it leads to degradation of the quartz envelope because oily finger prints diffuse into the hot silica.
