UV-Quartz glass is stronger than hard glass and highly resistant to temperature extremes and vibrations, which eliminates the risk of explosion. Philips quartz-glass lamps (filament 2 650º C and glass 800º C) are able to withstand severe thermal shock. With the capability to withhold increased pressure inside the lamp, UV-quartz glass is able to produce more powerful light. ^Application varies per bulb type

Only a burning bulb made of quartz glass (filament 2650°c, glass 800°c) can resist thermal shocks : such as, if a drop of cold water touches the hot bulb, when you drive through water with a broken headlight unit. ^Application varies per bulb type
