Explorer 2017 Extender Pack

Quick Overview

The elegantly designed CNC milled Explorer 2017 case has the same quality external look as other ranges of our lights although it features a complete internal redesign to house the latest generation of CREE LEDs. The new design significantly improves LED cooling, leading to better performance at lower speeds.

This unit is completely modular and compatible with all existing Lumicycle batteries and chargers. This hugely powerful 3 LED lamp will produce up to 3500 Lumens on *smart boost. It uses CREE XML2 LEDs to become an extremely bright single Lumicycle Lamp. The Explorer 2017 has more pronounced penetration and width beam wise than the Summit range, making it ideal for both straight tracks and gnarly single-track. It can also be used in city streets, urban environments and dark country lanes. This lamp unit is ideally suited to the rider who is looking for single off-road light that produces exceptional brightness with excellent width and length in the beam.

Our own team currently use these lights, as they are truly exceptional in every regard. They can run in a permanent boost mode of 3000 Lumens making them astonishingly bright or a 3-minute smart boost mode of 3500 Lumens.

This system comes with our extremely powerful 6.2 Ah Extender battery. This pack is designed to double the run time offered by our Explorer Enduro Pack and the battery will simply mount on a tubular part of your bike.

Additional Information

As well as a brand new thermal design the Explorer 2017 features six easily selectable power modes including Flash and a special Smart Boost mode. Designed for 3-minute sprints the Smart Boost delivers maximum performance at high speed. The new lamp unit also features a sleep mode to minimise battery drain when left connected to the lamp unit. The new lamp also benefits from an up-rated LED driver capable of delivering high current with up to 95% maximum efficiency. Once again we have selected slightly warmer colour LEDs for a more natural light and better colour rendering at night. A Smart Indicator on the back of the lamp gives information about the Power mode setting of the lamp and the condition of the battery.

One of the beauties of the lamp is simple up/down toggle switching which allows the user to easily go up or down through the power modes without the need to cycle through unnecessary settings. Features:
