The SEO 5 shines bright with 180 lumens on high, a red LED for preserving night vision, and a high end power white LED with flash function and a swivelling head that ensures you'll have light where you want it, when you want it. The advanced focus system allows for a close up spot or a wider beam, making the SEO 5 a flexible, lightweight, and technology centred headlamp for any sport, hobby or job.
LED Lenser SEO Series -Traditionally light focusing systems have consisted of either a lens, or a reflector. Lenses have the advantage of emitting a homogenous light pattern for distances almost 70% of the light is scattered and lost.
Conversely, while reflectors do a better job of capturing a higher percentage of light for long distances, when they are used for up close reading scattered light causes "rings" and "holes" in the light pattern leading to eye fatigue.
In both these cases, the lumen count (brightness) loses its validity as light is misdirected and wasted. That's why we decided to try something different.
If you pull together the strengths of the lens and reflector into one combined system, you achieve clear, homogeneous light spill for up close reading and a sharply focused beam for long distance viewing.
This is exactly what we've done with the Advanced Focus System (AFS); a unique and patented lens/reflector optic. AFS means reading the map up close is easy on the eyes and then focusing to find the path or landmark in the distance, clear and bright.
