About Halogen Torches
Halogen torches use a bulb filled with halogen or xenon gas to produce a bright light. The deposits which cause a standard bulb to darken over time are re-deposited on to the tungsten filament so there is minimal loss of brightness.
Halogen torches have, in recent years, become the standard “work horse” for divers and are cheaper than either LED or HID torches. Halogen torches are the “standard” in terms of battery life and provide a good all round torch for most purposes.
