CustomDUO modules


The Petzl Duo is an outstanding low-mid cost helmet mounted caving lamp. With a suitable LED upgrade (and decent quality low self discharge NiMh batteries) the Petzl Duo is without doubt the best mid range caving lamp available. CustomDUO LED Modules offer a significant upgrade to the Petzl Duo, replacing standard halogen bulbs and LED units.


CustomDUO modules are easy to fit, stylish, and use the most recent high power LED technology, incorporating the latest high power Cree LEDs (the brightest and most efficient LEDs available), to greatly increase light output and battery duration. CustomDUO modules are without doubt the brightest and most effective retrofit LED modules available for the Duo. 


A flexible range of CustomDUO modules are available to meet individual needs, featuring multiple power settings and user friendly modes developed specifically for cavers. The modules feature efficient current regulation circuitry, and discreet thermal management as required. Operating modes are versatile, yet simple and non confusing.
