Ledlenser® i4R CRI


i4R CRI Rechargeable Pen-shape Flashlight

Our industrial range penlight, the i4R CRI, is equipped with Ledlenser Natural Light. With a CRI rating of more than 90, the neutral white light is ideal for faithful rendering of colors and enhanced perception of contrasts. In addition, eye fatigue, due to working under artificial light for several hours at a time, is reduced. Thanks to the patented Advanced Focus System, the neutral white light distribution can be adjusted to the individual requirements of the task at hand.
