Explorer Extender Pack

Quick Overview

The Explorer Extender pack features a single Explorer light plus our hugely powerful 6.8Ah Lithium Ion battery, Standard Li-Ion Charger (see order options) and carbon fibre effect carry case; this pack offers excellent value for money for the rider that requires high performance lighting from a single light source with extended ride times - the larger battery capacity featured in this pack doubles the available run time compared to the Enduro battery.. Featuring the award winning Explorer specification as above presented in a hard wearing presentation pack to protect the light system when not in use. The system is modular and can be configured to any mounting option easily and quickly on its own, or by the use of extension cables enabling flexible mounting of the battery pack anywhere on the bike.
The 3500 Lumen smart boost output from the Explorer turns night to day with extremely good beam penetration for high speed confidence on gnarly off road sections as well as offering huge run times from the compact battery.

This system comes with our small, but powerful Extender 6.8Ah battery with two leads - enabling a second front, or tail light to be powered from the same battery - that can be mounted on any tubular part of the bike including under the handlebars, for a lightweight but durable off road solution.

Additional Information

The Explorer's external features now boast a two colour anodised finish, improved internal thermal performance and waterproof sealing. The light 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. At customers request the Explorer now also indicates the state of battery charge when you first connect the light. Improvements in the LED driver software also increase the efficiency of the Explorer system enabling greater run times - especially when coupled with our 6.8Ah battery packs . Working together this increases run times by up to 20% whilst still maintaining industry leading brightness. We have worked closely with CREE to identify a very special version of the XML2 LED used in the light - which has a high element of green/blue in its spectrum - whilst not obvious to your eye when riding (its just a crisp white light), but if you are riding through trees or foliage you will notice that the branches and leaves will become much more obvious. The Smart Indicator software has also been enhanced for, providing light output mode and battery health indicators on the back of the lamp.

One of the beauties of the lamp is simple, rugged up/down toggle switch that allows the user to easily (even with heavy gloves) go up or down through the power modes without the need to cycle through unnecessary settings.

Our 14.8 v Li-Ion batteries come in two capacities our Enduro 3.4 Amp/h and our Extender 6.8 Amp/h. Our Lithium-Ion batteries packs are made using the very highest quality Panasonic/Sanyo cells. The battery pack is the heart of any bike light system and we have found using these cells results in battery packs that typically last between 5-7 years when used and stored correctly.
