Our specialist Lamps are a variety of tungsten, halogen or LED. Available in a variety of wattages, designs and base connectors.
Halogen lamps have a compact lamp envelope and are more efficient that standard tungsten lamps.
The halogen cycle increases the lifetime of the bulb and prevents its darkening by redepositing tungsten from the inside of the bulb back onto the filament. The halogen lamp can operate its filament at a higher temperature than a standard gas filled lamp of similar wattage without loss of operating life. This gives it a higher efficacy (10-30 lm/W). It also gives light of a higher colour temperature compared to a non-halogen incandescent lamp. Alternatively, it may be designed to have perhaps twice the life with the same or slightly higher efficacy. Because of their smaller size, halogen lamps can advantageously be used with optical systems that are more efficient.
A halogen lamp is an incandescent lamp in which a tungsten filament is sealed into a compact transparent capsule filled with an inert gas and a small amount of halogen such as iodine or bromine.
