Picture gallery

Several notches allow front LED positioning to best adapt the lighting to your preferences. There are a total of 5 positions thus sweeping a wide angular range.

The gray button on the right side (practical for right-handers, a little less for left-handers) allows to switch on, choose the lighting mode and turn off the lamp.
It's practical and easily accessible, even with gloves.

There is also another button at the back, one press switches on the red rear LED, a second press allows it to flash, while a third press switches it off.
This button is also equipped with a scroll wheel to refine the lighting power, if you turn to the left the power decreases and it increases to the right.
In the flashing mode, it's also used to adjust the frequency of the white LED.

The back LED is also used to give the state of the battery, on power-up, the LED on the rear light up for a few seconds, if it's green, at least 50% charge remains, orange , between 50% and 20% and red, less than 20%.

On the right side at the back is the connector for battery recharging protected by a small plastic cap.

On the H14R.2 model the lamp is sold with a rechargeable Lithium-ion battery. It takes between 4 and 5 hours to fully charge it.

The battery is connected to the lamp via a waterproof connector.

It's thanks to this connector that you can insert the extension which allows to deport the battery to lighten the weight on the head.

a clip secures the battery compartment.

In terms of lighting, there is a great flexibility of settings, I will try to review everything that is possible to do.

I start lighting with the focus in beam mode, this is the mode I use when I ride a bike, to see far.
In this photo, you can see the beam with the minimum lighting (60 lumens).

Always with focus in beam mode with 350 lumen lighting. Knowing that you can easily adjust the power with the rear scroll wheel.

Always in beam mode with 850 lumen lighting. Note the presence of a bright halo in the bottom left and bottom right corners of the photo.

By putting the focus in wide mode, mode to favor for running, to see where you will put your feet.
In this photo, you can see the rendering with the minimum lighting (60 lumens).

Always with focus in wide mode with lighting at 350 lumens. Knowing that you can easily adjust the power with the rear scroll wheel.

Still with focus in wide mode with 850 lumen lighting, you can see that there is a great side view.

Technologies


Dynamic Switch	The dynamic switch of LENSER LED lamps allows you to change the light intensity with one hand in few milliseconds. Press and hold the switch, the lamp will provide maximum brightness (Boost), then release the button, the boost mode will remain active for few seconds before returning to the previous mode. The Boost function is available at all times (even when the lamp is set to “Low Power” or “Power”). When set to "Power", the lamp gives full light output. In "Low Power" mode the lamp shines with reduced brightness in order to consume less energy.
Speeed Focus	The "Speed Focus" focusing mechanism is fast, reliable and in many ways superior to conventional mechanisms for adjusting the luminux flux. It helps you create the right light for every occasion. In conventional systems, focusing is achieved by turning the head of the lamp. This solution is too slow and not really suitable if you want to use the lamp with one hand. This is why Speed Focus was developed, a pogressive focus adjustment mechanism by sliding in a single gesture.
Smart Light	The designers of LENSER LED lamps have created Smart Light Technology in order to obtain lighting adapted to each situation. This technology is based on computer-optimized microprocessors, the result is a perfect balance between a large number of different lights and their simple and quick adjustment with a single push button. There are several modes: Boost, Low Power, Power, DIM (adjustable from 15 to 100%) and Blink (Flashing).

Conclusion

This headlamp despite a high price (170 euros) is a pure wonder. It's easy to use and you can really adjust the beam to adapt it to your preferences. By searching on the internet, you can find it for 111 euros.


Wide choice of lighting power. Red rear LED, which can flash. Very good maintains in position. Remote battery thanks to the extension supplied. Indication of battery charge by color led.	Connector cover does not hold securely in place. Focus adjustment not very obvious. In beam mode, there is a slightly annoying luminous halo. Its weight can be inconvenient if you don't deport the battery. The charger cable is really very short.
