They are can be manufactured extremely compact and the bulb replacement costs are relatively low, extending the life of medical devices.

Medical: Halogen light bulbs are often used in medical devices, including dental and surgical overhead lights, examination equipment, microscopes and ophthalmoscopes, and surgery tools.

Many ANSI-coded lamps are still manufactured and used in these projectors and for other specialized applications

Projection: For legacy projectors like slide and overhead, halogen lamps were the most common lighting technology.

They are used to transfer large amounts of heat but are absolutely controllable, with evenly heated zones.

Heating: Infrared quartz heater lamps are widely used in consumer and commercial heating equipment.

Manufacturers like Osram, Philips, and Ushio have developed special halogen technology just for the entertainment industry. Follow spots and PAR cans are two common applications.

Stage/studio: Halogen lamps are used widely in the theatrical and studio industries.LEDs have largely replaced halogen in this application. General lighting: From recessed cans in a ceiling using halogen PARs to low-voltage landscape lighting using MR lamps, halogen has been a popular lighting solution for general illumination.Halogen bulbs can be found in a wide range of products of various applications. Many halogen lamps use a UV blocking element in the glass envelope to prevent the ultraviolet radiation from escaping the bulb glass. The bulbs produce a continuous spectrum of visible light, from near ultraviolet to infrared.Īlthough halogen lamps are not considered ultraviolet bulbs, they can emit some ultraviolet radiation, especially halogens using high temperature filaments.

They are also used in a wide variety of applications, from household lighting to stage/studio to medical.īecause of the higher temperature that halogen lamps operate at, they emit a higher color temperature than incandescent bulbs of a similar wattage. Halogen lamps come in a variety of sizes, from small bi-pin capsules to very large wattage specialty bulbs used in stage/studio lighting. Compared to incandescent light bulbs, halogen runs at a higher temperature, resulting in higher luminous efficacy and color temperature. Halogen light bulbs are incandescent lamps consisting of a tungsten filament inside of a transparent envelope.
