High voltage halogen lamps with reflector

A further development of the incandescent lamp, the high voltage halogen lamp (for 230 Volt line voltage) has quickly become an established light source. The advantages it offers: at least twice the life of an incandescent lamp (2,000 operating hours), higher luminous efficacy, constant luminous flux throughout its life – and the brilliance of halogen light.

The fact that the luminous flux remains constant throughout the operating life of the lamp is due to the halogen cycle. In it, tungsten atoms evaporate from the filament and combine with halogen atoms; the gaseous compound then returns to the hot filament, re-depositing tungsten atoms and releasing halogens; the cycle then starts again. There is thus no "lamp blackening" due to tungsten deposits on the bulb, so the luminous flux is not reduced.

High voltage halogen lamps with reflector are dimmable.

Parabolic aluminised reflector (PAR) lamps with screw base can simply be fitted in place of conventional incandescent PAR lamps. All other high voltage halogen lamps with reflector resemble their low voltage counterparts in appearance and lighting characteristics but are suitable only for 230 Volt line operation.

High voltage halogen lamps without reflector

Screw-based designs with clear or matt bulb can simply be fitted in place of conventional incandescent lamps. Double-ended high voltage halogen lamps (R7s base) are particularly suitable for floodlighting. The other high voltage halogen lamps without reflector (and without jacket) resemble their low voltage counterparts in appearance and lighting characteristics but are suitable only for 230 Volt line operation.

Characteristics:

"Tiny light source, lots of light" is a fair description of the low voltage halogen lamp. Thanks to the small dimensions, its brilliant light can be focused (spot) for precise highlighting (accent lighting) or spread for wide-angle lighting (wide flood).

Low voltage halogen lamps with reflector

The range of lamps encompasses models with metal or silvered glass reflectors of different sizes for different beam spreads. Cool beam reflector lamps – particularly suitable for protecting heat-sensitive materials – emit two-thirds of the heat generated at the back.

Low voltage halogen lamps with reflector can be dimmed. The dimmers need to be appropriate for the transformers or converters used.

Low voltage halogen lamps work on the principle of the halogen cycle, just like high voltage halogen lamps. The lower power consumption of low voltage lamps (and double-based 230 Volt lamps) is achieved by IRC (infrared reflective coating) technology. The special bulb coating reflects a major part of the IR radiation generated back to the coil. 

Low-voltage halogen lamps with reflector are not affected by Regulation 244/2009 "Ecodesign requirements for non-directional household lamps".

Low voltage halogen lamps without reflector are frequently used in "starry sky" configurations. To eliminate the risk of bulb-burst where lamps are free-burning (standard EN/IEC 60598), they are made in low-pressure designs.
