Headlamp Lucifer S2X+

Running headlamp Lucifer S2X+

A headlamp for runners, ultra-marathoners and all those seeking a bright light and wanting to minimize weight. The Lucifer S2X+ has an output of 1300 lumens and uses interchangeable 18650 batteries.

Lightweight and tough body

The headlamp body and battery pack are CNC milled from aerospace aluminium and anodized, which makes them very light and they doesn't overheat like regular plastic headlamps.

They are very stable on the head thanks to the distributed weight between the front and back. More

Efficient electronics prolongs runtime

The S2X+’s electronics are made entirely in-house from carefully chosen discrete components, all driven by an 8-bit Atmel microcontroller. The high quality components include X7R ceramic capacitors, very low resistance mosfets, a large shielded coil and precision thermistors and resistors - all ‘high reliability’ components, including the durable tactile switch, sealed and rated to 500,000 cycles.

The S2X+ headlamp uses CONSTANT CURRENT REGULATION so intensity in all modes is maintained as the battery discharges. When the battery is no longer able to deliver the current required by a chosen mode, the circuit simply switches to a lower one. The light never shuts down suddenly and shines without flicker (no PWM).

Our electronics monitor REMAINING BATTERY CHARGE and give 3 levels of warning, alerting the user to levels of battery discharge down to 33%, 10% or completely empty with 1, 2 or 3 blinks of the beam.

It also CHECKS THE TEMPERATURE and will reduce the mode in case of overheating. You can also easily find out REMAINING BATTERY CHARGE, the headlamp will notify you with 1-5 flashes. More

Easy one button mode switching

The S2X+ headlamp offers 5 light modes and blinking mode. There is no ‘last mode’ memory - it’s unnecessary when all modes are available with a maximum of two clicks. The light turns on the same way every time and turns off with one long press.

EASY USER INTERFACE is easily understood. Modes can be changed with short clicks, cycling through LOW-MID-HIGH-BOOST-LOW etc.

ADVANCED USER INTERFACE allows fast switching between modes. Modes can be changed with short and long presses. A short click lowers the mode and cycles between low and mid mode. Long press switches to a higher mode. More

Lower or Higher intensity in all modes

User could switch between lower and higher intensities. All 5 modes (VERY LOW, LOW, MID, HIGH, BOOST) have lower intensity (25, 90, 200, 425 and 1050 lumens) or higher intensity (25, 120, 240, 650 and 1300 lumens). Runtimes are based on this setting.

Extreme and real runtimes

Our headlamps have the longest real runtimes thanks to the latest Cree LEDs and high efficiency electronics.

5 modes with constant brightness control ensure high brightness from start to finish. More

Brilliant LEDs CREE XP-L2

We use high power CREE XP-L2 LEDs with a 4500K color temperature providing a pleasant neutral white color with excellent color spectrum. Thanks to the lower color temperature the light is able to better penetrate fog and rain, improving judgment of distances, differentiation of colors and identification of obstacles and detail in the environment.

The S2X+’s LEDs and electronics are on a single, copper printed circuit board with a Direct Thermal Path that enables quick transfer of heat to the aluminum shell - the most effective LED cooling system available! More

User-accessible battery tube for 1 li-ion 18650

Our Lucifer S2X+ headlamp uses protected li-ion 18650 cells which are readily available and currently provide the highest capacity of all li-ion batteries.

Spare cells can easily be carried for over-night use, minimizing weight on the head while still providing very long runtimes. The battery tube opens with a screw cap and changing cells is easy. More

High-current connectors and tough cables

The connectors are specified for currents up to 7A and ensure firm and reliable contact over the long-term. These connectors are injection molded in our workshop giving us full control over quality. Although they click together tightly (making accidental disconnection nearly impossible) they are easy to, even in difficult conditions when wearing gloves or in extreme cold.

Our grey PUR cables are special, they are tough, flexible to minus 30°C and very resistant to wear and weather. More

Extensive mounting and charging options

You can turn the headlamp into a helmet light in a few seconds. We have plastic and aluminum handlebar holders for all existing handlebar sizes. We also have holders for smooth and work helmets, a GoPro holder and different sizes of extensions from 5cm to 1m.

You can charge in an external charger or in the headlamp via the wall charger or our USB charger. More

Guarantee and post-warranty service

Our warranty period is 4 years but we can provide ongoing repairs after this period. Because we manufacture all of our headlamps ourselves all parts are available and we can offer comprehensive support.

We make a great effort to satisfy our customers and to ensure minimal warranty repairs. We also guarantee the availability of spare parts and repairability for at least 10 years.
