Key features of the Mactronic Black Eye H40:

Triple light source system for maximum flexibility

The H40 has three independent LED light sources that can be used in four operating modes:

• SPOT – a narrow, long-reaching beam for illuminating distant objects, up to 245 m away.

• FLOOD – a wide, diffused beam, ideal for close work and navigation.

• SPOT + FLOOD – combined illumination for maximum field of view.

• RED – low-intensity red light, designed for discreet operations, night vision, and eye adaptation to darkness.

Additionally, the RED FLASHING mode provides noticeable signaling light in emergency or tactical situations.

BOOST mode

Double-pressing the button activates BOOST mode instantly for any selected light configuration: SPOT, FLOOD, SPOT + FLOOD, or RED.
