Headlamp Lucifer S2X
Availability: In Stock
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 1200 lumens and uses interchangeable 18650 batteries.
Light aluminium body | DETAILS
Lightweight and tough body
The headlamp body and battery pack are CNC milled from aerospace aluminium and anodized. The body is small and light with multiple cooling fins. The battery tube is also as light as possible but still strong and waterproof.
Interchangeable li-ion cells | DETAILS
User-accessible battery tube for 1 li-ion 18650
Our Lucifer S 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. Threading offers long life.
Battery tube is designed for protected 18650 batteries. Unprotected 18650 cells will work at your own risk and we dont recommend using them.
New high-current connectors and tough cables | DETAILS
The S2X incorporates new connectors and cables connecting it to the battery pack. The DC5.5/2.1 connectors are injection molded in our workshop giving us full control over quality. They are fully compatible with all of our previous battery packs and headlamps.
Our grey PUR cables are special, they are tough, flexible to minus 30°C and very resistant to wear and weather. We have carefully designed the wiring to fit all head sizes from large men to small women. The connectors are specified for currents up to 7A and ensure firm and reliable contact over the long-term. 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.
Efficient electronics | DETAILS
State of art technology with high efficiacy switching converters
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.
Making the circuit in-house means we are no longer tied to any specific controller hardware and we can easily upgrade firmware and add other features to optimize performance. As a result our electronics drive the LEDs at up to 96% efficiency giving longer runtimes.
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.
Brilliant LEDs CREE XP-L2 | DETAILS
Maximally efficient and vivid true colors
We use high power CREE XP-L2 LEDs with a 4500K color temperature providing a pleasant neutral white color with excellent color spectrum (CRI index min. 70). 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.
Maximum output of the Lucifer S2RED is 1200 lumens ANSI. LED efficiency is influenced by cooling - better cooling of the LEDs means more effective light output. The S2RED’s LEDs and electronics are on a single, copper printed circuit board with a revolutionary Direct Thermal Path that enables quick transfer of heat to the aluminum shell - the most effective LED cooling system available!
Perfect light distribution | DETAILS
Natural and smooth illumination
Both white and red LEDs has its own PMMA TIR lens which defines the width or focus of its beam. These lenses ensure the best optical properties for each of the three beam angles available - narrow 13°, medium 20° and wide 29°.
Generally 20° is for all sports. For close up work choose 29°. For fast sports you can also choose 13°, even this narrowest optics has got some side illumination.
For red LED we recommend 20° optics.
Modes and user interface | DETAILS
2 separate user interfaces
The S2X headlamp offers 7 modes - VERY LOW, LOW, MED, HIGH, BOOST, BLINKING MODE and SOS. The four most frequently used modes (LOW, MED, HIGH and VERY HIGH) are easily accessible.
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 or long presses. A short click lowers the mode and cycles between low and mid mode. Long press switches to a higher mode.
The remaining 3 modes are the same for both interfaces. You access VERY LOW mode with two consecutive button clicks, BLINKING mode with three and SOS mode with four clicks.
All mode switching in advanced user interface is based on short/long button presses. You can try this out at our website using your computer’s mouse. Our default advanced interface is here: https://www.luciferlights.net/interactive, and our easy interface here: https://www.luciferlights.net/interactive_alt.
Two intensity presets
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, 100, 230, 470 and 950 lumens) or higher intensity (25, 100, 230, 600 and 1200 lumens). Runtimes are based on this setting.
Switch of intensity is done by 15 second or longer button press from the off state. The headlamp blinks one or two times. One blink indicates you switched to the lower intensities. Two blinks means you switched to higher intensities. From the factory its set to higher intensities.
Runtimes | DETAILS
Extreme and real runtimes
in constant regulation hours : minutes
in constant regulation hours : minutes
The runtimes specified for 1 cell 3450mAh are minimums until the intensity drops below 70% of original value. When the battery cannot supply enough energy for a specific mode the headlamp switches to the next lower one. When it reaches the lowest mode it will no longer regulate brightness and light output gradually diminishes, giving plenty of warning before shutting off.
Note that we specify runtimes more strictly than the ANSI NEMA FL-1 standard requires. ANSI accepts a drop in intensity down to 10% of the original which makes no sense - our runtimes reflect the practical illumination needs of real users!
Wall charger and charging
Battery is supposed to be charged with wall charger or with bay charger. Wall charger is very simple in operation, you just connect it with the battery tube. Bay charger Lii-100 offers many possibilities and features but requires battery to be unloaded from the battery tube.
Wall charger 4.2V/0.5A is currently offered with just an EU plug. This charges the cells with a low current to prolong their life. Charging of a fully depleted battery takes 7.5 hours. A red indicator lights up during the charging and changes to green when complete.
Second option is USB bay charger Lii-100, small charger capable of charging li-ions or any other chemistries (NiMh,NiCd). It is powered from any USB port. User can select between two charging speeds (curents) 0.5A and 1A. It can also power any USB device from included battery.
