Metal halide bulbs are becoming more commonly available. They produce heat, UVB, and infrared light. Their beam is very narrow compared to all other bulb types which means that they can provide very high UVB levels but over a narrow area, which may be a positive feature in some enclosures (e.g., tall enclosures) but dangerous in others (e.g., short enclosures). These bulbs require external ballast and a properly rated fixture for operation and safety. Their use is best reserved for advanced hobbyist familiar with the principles of UVB lighting.
