New for Summer 2016 - the Flexitwin V5 twin-beam insert for Duos. The latest evolution of the Flexitwin unit, giving serious output and unrivalled flexibility in use.
The Version 5 Flexitwin has arguably the best available user interface for a twin-beam headlight, combining a high level of control with simple operation and neat features like easy reversible access to a full-power spot beam, and a 'boosted high' setting to automatically combine maximum light output with excellent runtime.

While the Flexitwin comes preconfigured, it is easily reconfigurable to change various options to suit a variety of user tastes.
