CustomDUO design and manufacture retro-fit LED modules that significantly upgrade the original Petzl Duo, almost certainly the most widely used caving light globally.
Established in 1995 (as LED-Techno) Customduo developed the earliest white LED caving lights, in the form of LED upgrades for mining lamps including helmet mounted battery packs, commercially available (1997) from caving retailers in the UK and other countries. We still manufacture CustomPITLAMP modules for mining lamps, albeit difficult to recognise from our original upgrades.
Based in the UK, Customduo also design and manufacture a range of other specialist underground lighting related products, including Rude Nora and Filthy Edna ............... the Little Monkey caving lights www.littlemonkeycaving.co.uk
