TIR stands for Total Internal Reflection and are cone shaped reflector lenses in which all light from the LED is reflected before being distributed outwards. This gives better control of the light output, providing a clearer, sharper, and more focused headlamp beam.

With the total light control the TIR lens provides, our headlamps are able to deliver outstanding peripheral vision with a soft and wide spread light beam. This gives you an expanded field of vision and reduced eye fatigue.

Our lenses have two primary light beam spread angles: 15° (narrow) and 30° (wide).

The Noctia system, and the Bright As Day 800 and 1300(S) have one 15° center beam and one 30° peripheral vision beam. This gives a crisp clear light in the center, with an expanded peripheral light surrounding the core of the beam.

The more powerful Bright As Day 2000, 3000, and 4000 are equipped with two, six, and eight 15° beams accordingly. These are angled in individual directions, acting together to provide a broad field of sharp and clear light.

Our lenses are made from durable and crystal clear polycarbonate to give you the best possible visibility in all conditions.

A Moonlight headlamp is designed to last. The lenses are highly durable and scratch-free, allowing you to focus on your own adventures and performance, rather than being concerned about your light becoming uneven or unclear.

Accidents may of course happen, and should you be unfortunate, the lens is easily replaceable and we have spare parts readily available to serve your needs.

Our headlamps are tailored to the intended use. This is why the lighter headlamps that are perfect for technical trail running, such as the Noctia and the Bright As Day 800, have a broad field of light with a concentrated crisp centre - allowing you to see your next step far ahead.

The more powerful Bright As Day 2000, 3000, and 4000, perfect for skiing or mountain biking, on the other hand, have even broader light beams without a focused centre, giving you the best possible view and visibility of your surroundings when you're biking down a narrow forest trail or navigating a steep couloir on skis.
