Not sure what we're talking about? The gas in a bulb usually works at a higher pressure--the glass bulb is typically made of high-silica glass, aluminosilicate, or fused quartz. It is a stronger variety of bulb than the standard glass type you are used to, as it needs to contain the high pressure within. This kind of lamp has been an industry standard for film and television, owing to its high lumen output and compact size. Increased efficiency varieties that comprise 30+ lumens per watt are starting to take the market by storm. The advantages of this kind of lamp are numerous; they're smaller, dainty, and light weight, and are cost-effective to produce. They also do not use potentially harmful chemicals, unlike mercury vapor types and CFLs. What's more, they offer better color temperature than a standard tungsten and are closer to the sunshine than are the more orange hues available from older varieties. These products also offer longer lifespans that a conventional incandescent and are instantly bright when turned on - no warm up time required.
