Over the past couple of weekends I've had the opportunity to test LED
Lenser's H7. This product is fantastic.
This lightweight headlamp provides functionality and versatility that I
have yet to see in other brands. At a sparse 4.13 ounces, it is super
lightweight and packs extremely small for the amount of functions that it
provides. The Advance Focus System allows you to adjust the beam from a
flood light to a spot light and the stageless dimming function allows you
to adjust the intensity and save your batteries.
Whether you're walking into your favorite honey hole or looking for a
toothbrush in your tent the low intensity circular beam provides you with
more than enough light. When you focus the beam this little beauty
provides 155 lumens of light which is more than enough to leave those high
intensity handheld flashlights at home. I'm a huge believer that any time
you can find something that will eliminate two items out of your pack it's
a great find. In addition, you have a swiveling light design which is
really handy in the field.
Most impressive about the LED Lenser H7 though may be the price. At $46.99
this lightweight gem outperforms in versatility and function most of its
competitors at twice the price.
LED Lenser H7 Headlamp
The pros are thrilled. With the H7, they get the lightweight, easy-to-wear feeling of the H5 but with six-times the lumens. The Advanced Focus System adjusts for either long-distance light or a circular low beam, making outdoor activities more comfortable and safer. The pros are thrilled.

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 patented Advanced Focus System (AFS); the only light-focusing system of its kind. 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
