Specifically designed for tough and demanding jobs, the lamps of the i-series are robust and functional companions. The "i" in the name of the Ledlenser i-series stands for industry. The yellow-black models are sturdy buddies, functional colleagues, and enduring companions. All lamps are also available in a rechargeable version with a battery. The i-series combines sustainability with functionality, is powerful, easy to handle, and offers excellent value for money – the first choice for craftsmen, electricians, and industrial workers.

Advanced Focus System: Galileo swore by the power of the lens, Newton by that of the reflector. We simply combined both technologies – but perfected like never before. The result: our patented Advanced Focus System (AFS), which allows for a seamless transition from homogeneous near light to sharply focused far light. The AFS boasts an efficiency that even impresses experts.

Safety Ytrion Cell: A Safety Ytrion Cell is significantly lighter than a nickel-metal hydride battery and charges up to five times faster than a lithium-ion battery. At the same time, it offers more than 5,000 charge cycles with virtually no capacity loss due to "memory effect."

Temperature Control: Hard work keeps our lamps cool: A Ledlenser will never get too hot thanks to intelligent and fully automatic Temperature Control, no matter how much it is used. This protects you from burns and the LED from overheating.

Rapid Focus: When focusing and defocusing the flashlight or headlamp, our reflector lens moves relative to the LED. To make this process as quick and ergonomic as possible for users, we developed Rapid Focus: a one-handed mechanism that allows you to adjust the beam of light in an instant.
