Head torch Lucifer Z1

Dear customers, this headlamp is not currently available. We work on improved second version Z2. Shall be stocked in May/June 2022.

currently we are restocking parts for this head torch. Sizes 18350 and 18500 will be restocked around 8.4.2021. Size 18650 will be stocked in the second half of March.


A headlamp for runners, ultra-marathoners, travellers or adventurers. The Lucifer Z1 has an output of 800 lumens and uses interchangeable li-ion batteries.

Ultralight headlamp | DETAILS

Easily packable in a pocket

This is the worlds first headlamp capable of continous light of 800 lumens and with total weight under 100gr. CNC milled aerospace aluminium body allows uninterrupted use on the highest mode. The body was made with the lowest weight in mind and is very packable and fully waterproof.


3 headlamps in 1

Maximum versatility with 3 battery sizes

This headlamp can use three different battery sizes. The larger battery, the longer runtimes and also larger weight. Choose your best size / runtime option!

Smallest option with battery size 18350 (1200mAh) is packable headlamp which easily fits your pocket. It weights just 94 gr. and is good for everyday carry and general sporting. Perfect replacement of all your AA/AAA headlamps.

Middle option uses battery size 18500 (2050mAh) and is still very packable headlamp with total weight of  122 gr. Its perfect when mounted on your bicycle helmet or used in longer running events. Offers good weight/capacity compromise.

The largest option uses size 18650 (3450mAh) and weights 138 gr. Its good for ultra marathoners, when mounted on your bicycle helmet or bike handlebars. Offers longest runtimes in still compact body.

Efficient electronics | DETAILS

State of art technology with high efficiacy switching converters

The Z1’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 Z1 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.



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 Z1 is 800 lumens ANSI. LED efficiency is influenced by cooling - better cooling of the LEDs means more effective light output. The Z1’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

White 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 reccomend 20° optics.


Modes and user interface | DETAILS

2 separate user interfaces

The Z1 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, long and very 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:, and our easy interface here:

Two intensity presets

Lower or Higher intensity of all modes

User could switch between lower and higher intensities. All 5 modes (VERY LOW, LOW, MID, HIGH, BOOST) have lower intensity (13, 75, 160, 300 and 600 lumens) or higher intensity (13, 100, 200, 400 and 800 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.

The runtimes specified for 1 cell 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!

Obsah balení čelové svítilny Z1

Battery is supposed to be charged with appropriate li-ion bay charger, like Lii-100 charger which offers many possibilities and features. Lii-100 is small USB 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.


Lucifer Z1 headlamp can be easily mounted on a bicycle helmet or handlebars with various mounts. There is also many batteries and chargers that can be bought locally from other companies. We however recommend using our bay charger and batteries as they were tested and perform great.
