The HD Pro Battery Pack frees your light from being tied to the wall, without compromising performance. Read anywhere in the house - move to the conservatory, the spare room, wherever the mood takes you.

Engineered to deliver unwavering power, the battery provides a full 6.5 hours of consistent, full-strength light. The circuitry is designed to prevent brightness from fading as the battery drains - the first hour is as bright as the last minute.
