User Manual
Safety precautions
• Use only reputable 21700 cells of known origin.
• Remove and recharge the cell when the low
voltage indication is given by the Lamp (repeated
step-downs in light level and eventual shutdown of
the light).
• The extraordinary energy density that 21700 cells
offers also means that hazardous conditions are
created when a cell is short-circuited or damaged.
Always treat cells with respect and properly
dispose of damaged cells.
• The EC01 is a very high-intensity flashlight. Do not
point directly at a person, animal, moving vehicles
or flammable materials.
• When running at higher output levels the head of
the Lamp will quickly heat. This is normal. In
warmer ambient conditions this temperature may
exceed 50ºC depending on your settings, so please
take the necessary precautions when handling the
Lamp.
Quick start
• Use one 21700 cell.
• Unscrew the head and insert the battery. Take care
with the polarity: Plus points toward the head.
• Screw the head back. The EC01 blinks once to
confirm it has power and is now operational.
Tighten the head. Do not over-tighten.
• All functions are performed using the electronic
side switch. And basic usage is very simple: Click
for on/off, hold to change brightness. Release and
hold again to change brightness the other way.
• From OFF, hold the button. The light output will
ramp up from a very low level to Ceiling-Of-TheRamp. Release the button when the required light
level is reached. (The full ramp takes about 3 s.)
Use a single-click at any time to turn the EC01 OFF.
Please see below for further details.
• While ramping it does subtle blinks to signal: Max
regulated level (1x7135) and CEILING.
• The EC01 has two different ramps: SMOOTH RAMP
and STEPPED RAMP. You can change between
them when the lamp is ON with three clicks. Each
ramp has its own individual settings – for floor
(lowest level), ceiling (highest level). And the
stepped ramp can also have a configurable number
of steps.
• TURBO is only for short times. At around a minute
you may notice it dims slowly down! The user
should use it only for short periods instead of
relying on thermal regulation to prevent heat
damage. Full turbo is powerful enough to start fires
in just a few seconds, especially when aimed at
dark-colored materials.
Integrated charger
The EC01 has a USB-C charging port. Please use a
premium cable and a power adapter with 5V, 2A to
charge your lamp.
While charging the switch LED is red. It goes green
when charging is finished. .
While charging you can use BattCheck mode from the
Group 1 Blinkies to check the voltage level and all other
flashlight functions can be used normally when
charging.
Specifications
A 21700 CREE LED lamp with side switch and a great,
easy user interface.
Emitter: CREE XHP50.2(3V) LED on a copper DTP MCPCB
Lens: High transmittance glass
Flux: ~3500 lm
Throw: ~298 m
Firmware: The EC01 uses free software called Andúril,
distributed under the terms of the GPL v3.
Code is available from
http://tiny.cc/TKAnduril
User interfaces: [1] By default the EC01 is set to use
SMOOTH RAMPING. Instant access to
TURBO mode is also provided.
[2] A more conventional STEPPED
RAMPING UI is available if you like discrete
modes level. You can choose how many
steps you want.
[3] MOMENTARY mode is useful for
signaling purposes or rapidly/briefly
lighting up targets. To exit this mode,
physically disconnect power
[4] MUGGLE mode uses a reduced output.
[5] It has an electronic LOCKOUT for safety,
but acts also as momentary low light.
Other functions: Battery check, sunset, beacon,
tactical strobe, party strobe, bike flasher,
candlelight, lightning storm
Battery: one premium 21700 cells. Unprotected cells
are recommended.
Charging: Integrated charger via USB-C
Driver: FET+1 driver. Low parasitic drain while OFF
Body: Aluminum with HA III anodizing
Switch: Electronic side switch
Ingress rating: Equivalent to IPX8
Weight: Approximately 119 g without cells
Size: 37 mm Ø head x 120 mm length.

UI Diagram
Not everything is covered in the diagram, please read the text.
Default UI: Smooth ramping
This UI provides smooth dimming of the light output
between FLOOR (lowest level) and CEILING (highest
level), with an easily accessible 100% TURBO mode.
Switch to STEPPED RAMP: If the lamp is ON:
Three clicks
(Hint: If you use 3 clicks from
OFF you engage battery check)
Turn the lamp ON: single-click the button, the EC01
turns ON using the previously
used light output level (MEM)
Ramp up; brighter: hold the button
Reverse ramp: while ramping in one direction,
release button briefly and hold
again
Ramp down; darker: Click, hold, when ON
(means: double-click, but hold
the second click a bit longer)
If you do this when the lamp is
OFF, it ramps down from the
CEILING (dashed double lines)
Instant top CEILING: from OFF: double-click
(double lines)
TURBO: from ON: double-click toggles
between turbo and the
memorized level
from OFF (You must first switch
ON): Click, then double-click
FLOOR / MOON mode: from OFF: Hold
turns on at the FLOOR level, it
makes a subtle “blink” to provide
a timing hint if you want to stay
there.
If you keep holding, it ramps up
Battery check: from OFF: triple-click (4 blinks, a
short pause, then 1 blink would
indicate 4.1 V)
Turn the EC01 OFF: single-click
UI: Stepped ramping
Using this UI the output does not ramp, it steps from
one mode to the next using hold. The firmware tries to
optimize these steps as equally-spaced on a cube-root
curve (considered an ideal mode-spacing by many).
In STEPPED RAMPING you can choose how many steps
you want. (See Ramp configuration for details).
All operations are the same as in smooth ramping
Switch to SMOOTH RAMP: when the lamp is ON:
Three clicks (Hint: If you use 3 clicks from OFF you engage
battery check)
UI: Momentary mode
5 clicks from OFF to enter Momentary mode
To exit this mode, physically disconnect power
(unscrew the light).
This mode locks the flashlight into a single-mode
interface where the LEDs are only on when the button
is held down. It is intended for Morse code and other
signaling tasks.
Brightness is the last-ramped level, so adjust that
before entering momentary mode.
UI: Muggle mode
Muggle mode is for lending the EC01 to others. It has a
reduced output to make sure somebody won’t start a
fire. An extremely simple interface with a limited
brightness range — ~5 lm to ~240 lm, with slow
smooth ramping and no blinkies. Persists after a battery
change.
MUGGLE mode ON: from OFF 6 clicks to enter
MUGGLE mode OFF: 6 clicks to exit
One click ON / OFF and HOLD to ramp up / down.
UI: Electronic Lockout
4 clicks form OFF to disable the EC01, same to reenable the lamp.
Lockout makes the light safe to carry in a pocket or a
bag or anywhere else it might be pressed by accident.
Lockout doubles also as a momentary moonlight mode,
so the user can do quick tasks without having to unlock
the light. It uses the FLOOR of the current ramp.
