LUXOS U
Specific instructions
and information
Efficient use
of energy:
Distribution of
energy for
light and
functions
LUXOS U
creates a
homogenous field
of light
that is
up to
800% brighter
and 200%
wider than
required by
German road
traffic regulations.
Please note:
Lighting
of the
road varies
depending on
speed, operating
mode and
charging status
of the
integrated cache
battery. The
slower
one cycles
(below 15
km/h) the
brighter the
road immediately
in front
of the
bicycle is
lit (panorama
light at
close range,
see below)
while the
far range
is darker.
When the
velocity increases,
the light
distribution is
reversed.
The LUXOS
U offers
functions and
features that
no other
previous head
-
light had.
Hub dynamo
energy is
used with
maximum efficiency.
Output
of currently
known hub
dynamos might
deviate by
up to
40%. By
nature,
this energy
is limited
and insufficient
to always
power all
functions of
the
LUXOS at
full power
simultaneously. Therefore,
the energy
use has
to be
controlled and
distributed reasonably:
Headlight
switched on
The integrated
cache battery
is charged
during cycling
while at
the
same time
the light
shines. During
the short
while it
takes for
the
battery to
charge, the
light output
is reduced.
As soon
as the
cache
battery is
charged, the
maximum energy
is available
to the
light func
-
tions: panorama
light at
close range,
floodlight, daytime
running light,
standlight. When
the light
is switched
on, the
battery is
recharged
when the
velocity exceeds
15 km/h,
while the
use panorama
light at
close range,
floodlight or
standlight discharges
the battery.
Headlight
switched off
Only when
the headlight
is switched
off, USB
charging energy
can
continually be
provided at
more than
100 mA.
(See below:
USB char
-
ging.) Charging
energy is
stabilised by
the cache
battery, so
even
sensitive mobile
devices may
be charged.
Due to
the limited
amount
of energy,
no light
functions are
available during
charging.
Parked
bicycle
If the
integrated battery
was charged
during cycling,
the stored
energy can
be used
for charging
or powering
USB devices
(limited
energy).
Panorama light
at close
range
Two additional
LEDs in
the “forehead”
of the
LUXOS shine
onto the
road
directly front
and to
the side
of the
bicycle and
provide additional
light
width at
absolute close
range. Panorama
light at
close range
is controlled
automatically: When
cycling slower
than approx.
15 km/h,
the panorama
light at
close range
activates automatically.
The slower
one drives,
the
brighter this
light gets.
Floodlight mode
also activates
panorama light
at
close range
(maximum light
output, only
possible when
cache battery
is
charged).
Floodlight
When floodlight
is activated,
both the
energy currently
being provided
by
the dynamo
and the
energy stored
in the
cache battery
are used
in their
entirety for
maximum light
output. Floodlight
is ideal
for rides
in pitch
darkness and
when abruptly
switching from
bright to
dark surroundings.
It can
also be
used as
a flashing
headlight. Floodlight
is aided
by the
lithium cache
battery and
shines as
long as
the energy
reserve allows.
(If
the cache
battery is
fully charged
and if
one cycles
at approx.
25 km/h,
roughly 15
minutes of
floodlight are
available.) Floodlight
is switched
using the
push buttons
(quick push,
ON/OFF). Floodlight
duration is
limi-
ted (available
until the
cache battery
is exhausted).
Standlight
LUXOS U
continues shining
when the
bicycle stands
still. The
technology:
During cycling,
part of
the dynamo
energy is
stored in
the lithium
cache
battery. When
standing still,
this energy
powers the
headlight’s LEDs
so
that the
headlight continues
to shine.
Standlight can
be deactivated
pre-
maturely with
a long
push on
any button.
Switching options
The LUXOS
U has
a push
button on
its casing
as well
as a
separate hand
-
lebar push
button. Connection
of the
handlebar button
is optional.
We
recommend this
connection, because
only then
USB charging
is available
and because
floodlight and
flashing headlight
can easily
be triggered
while cycling.

The push
button is
mounted to
the handlebar
using a
rubber band
or cable
strap. Open
the rubber
cap on
the right
side of
the headlight
casing. Firmly
insert the
cable (lug
jack) as
far as
it will
go.
The L-shaped
lug jack
has to
point downwards
for safe
operation, this
also
forms a
draining sling
for rainy
weather or
splashing water.
Please note:
Ensure
a proper
fit of
the lug
jack in
the headlight
to pre
-
vent faulty
operation! Guide
the cable
in a
way so
the lug
jack may
not
inadvertently be
pulled out
of the
connector.
Please note:
Keep
rubber cap
closed when
not using
the handlebar
button –
moisture on
the lug
jack or
inside the
connector compromise
the
headlight’s functions.
Liability for
such damages
is excluded.

USB charging
energy
5
Integrated into
the handlebar
button below
a rubber
cap is
a USB
socket
which can
be used
to charge
or power
USB devices.
During rain,
the USB
socket cannot
be used
and the
rubber cap
has to
remain closed
(alterna-
tively, the
socket may
be protected
against moisture
e.g. by
sheathing it
in plastic).
A red
LED in
the handlebar
button indicates
when USB
charging power
is
available. This
is the
case when
the integrated
cache battery
(see below)
has sufficient
energy available.
Connected devices
are provided
with 5
V
and up
to 1
A current.
The charged
cache battery
keeps the
energy supply
constant during
slow rides
and stops
so that
sensitive mobile
devices may
be charged.
If the
charge of
the cache
battery drops
below a
certain level,
USB energy
supply is
interrupted (red
LED ceases
shining) until
the battery
is sufficiently
charged once
more.
Tip: Before
a USB
device is
connected, cycle
for some
minutes with
the
light switched
off so
the cache
battery has
sufficient basic
charge.
Permanent USB
charging with
more than
100 mA
is
only possible
when
all light
functions are
switched off.
When the
cache battery
is charged,
simultaneous charging
and use
of the
light function
is temporarily
possible.
The duration
of this
depends on
the charging
status of
the cache
battery,
the cycling
speed, the
quality of
the dynamo
and the
energy demand
of the
connected USB
device. While
the cache
battery discharges,
the light
output
diminishes. As
soon as
the light
output drops
below 20
Lux, the
USB ener
-
gy is
interrupted. The
light will
not deactivate
during cycling.
It
cannot be
guaranteed that
all connectable
USB devices
can be
powered/charged. Please
contact the
device manufacturer.
Please note:
Most
USB devices
have an
automatic charging
deactivation
which provides
overloads. If
such a
deactivation is
not available
but the
device shows
the charging
status, the
device has
to be
disconnected from
the handlebar
button as
soon as
it is
fully charged.
If neither
automatic
deactivation nor
charging status
display are
present, a
warming battery
is
a sign
for overloading.
Function and
output of
the integrated
lithium
cache battery
The lithium
cache battery
powers standlight,
panorama light
at close
range and
floodlight. It
also ensures
that the
charging energy
emitted via
the USB
socket is
constant during
slow rides
and stops.
When the
cache
battery’s charge
drops below
a certain
level, it
ceases providing
energy
until it
once more
possesses sufficient
charge.
If the
cache battery
is empty,
it takes
about ten
minutes of
cycling at
15
km/h to
charge it
completely, if
the headlight
is switched
of and
no USB
devices is
connected to
the handlebar
button.
While parking
with the
light system
switched off,
a fully
charged cache
battery can
supply a
connected USB
device with
energy for
approx. 4
minutes. For
energy preserving
reasons, the
energy supply
is interrupted
after that.
By moving
the bicycle,
the USB
energy supply
can be
reacti-
vated.
Please note:
After
longer periods
of non-use,
it may
take several
seconds of
cycling in
order for
light to
be available.
If the
cache battery
is emptied
and the
headlight is
not used
for several
months afterwards,
it
takes approx.
20 seconds
of cycling
for the
cache battery
to be
charged
so normal
light function
is possible.
It is
also possible
that after
a longer
period of
non-use it
takes several
seconds of
cycling before
light is
availa-
ble.
This can
be prevented
by charging
the cache
battery before
a longer
peri-
od of
non-use (e.g.
“hibernation”). To
do this,
it is
sufficient to
cycle for
ten minutes
without using
either light
or USB
charging functions.
Rear light
monitor
In the
headlight push
button, the
green LED
(RL) shines
constantly when
a rear
light is
connected to
the headlight
that functions
properly. In
case
of a
short circuit
or increased
energy consumption
of the
rear light,
the
green LED
flashes. If
the rear
light fails,
or if
no rear
light is
connected,
the green
LED ceases
to shine.
Please note:
If
a rear
light with
standlight function
is connected,
an
empty standlight
capacitor may
lead to
temporarily increased
energy
consumption (green
LED flashes).

General instructions
and information
Mounting
Mount the
headlight to
the bicycle
securely using
the pre-mounted
stain-
less steel
bracket or
another suitable
bracket. Adjust
its height
so onco
-
ming traffic
is not
glared. The
brightest section
of the
light field
should be
in ten
metres distance.
Tighten screws
so the
headlight cannot
shift posi
-
tion by
itself. After
establishing the
electrical connection
and mounting,
a
plastic cable
guide (two
parts, included)
can be
clipped around
the bracket
to protect
and hide
the wires.
German traffic
regulations require
a white
front reflector.
To achieve
this,
the enclosed
reflector can
be clipped
onto the
bottom of
the headlight.
Please note:
Always
observe proper
polarity: +
= current,
— =
ground.
Ground connection
via the
headlight’s mounting
bracket is
not possible.
Connection to
dynamo and
rear light
1
Connect the
cable coming
from the
dynamo to
the push
on contacts
mar-
ked “in“
on the
headlight. If
no cable
is connected
to the
dynamo yet,
use
the included
twin wires.
The push
on contacts
marked “out”
are for
connecting a
rear light
with
twin wiring.
This connection
has to
be done
with twin
wiring and
without
mass contact
(i.e. no
electrical connection
to the
bicycle frame).
Rear
lights offering
mass contact
via their
mounting screws
have to
be moun
-
ted without
electrical connection
to the
bicycle frame.
Daytime running
light. LICHT24
The headlight
is equipped
with daytime
running light
and has
two modes
of operation.
The headlight
is controlled
by a
light/dark sensor.
During
bright conditions,
the headlight
functions in
day mode.
During dusk
and
darkness the
headlight automatically
switches in
night mode.
Day mode
The
headlight shines
dimmed onto
the road,
the additional
daytime running
LEDs shine
with full
intensity. Maximum
visibility for
oncoming traffic!
Night mode
The
headlight shines
with full
brightness (70
Lux) onto
the road,
the additional
daytime running
LEDs shine
with
diminished intensity.
Maximum vision,
additional visibility
for oncoming
traffic!
Further information
The overvoltage
protection permanently
guards the
headlight, even
if no
rear light
is connected.
Please note:
The
headlight can
only be
powered by
a dynamo
(AC).
Connection to
a DC
power source
(battery) is
not possible.
Only special
e-bike versions
of the
LUXOS E
can accept
DC power
from 15
to 75
V. Please
ask your
specialised retailer.
Warning! Protect
LUXOS against
water damage:
If
the bicycle
is
transported upside
down on
a car
during rain
or cleaned
with water,
the
headlight must
be protected
so that
no moisture
may enter
via its
bottom
apertures (e.g.
by covering
it with
a plastic
bag).
Our rear
light tip:
LUXOS
is ideally
combined with
an energy
saving rear
light –
this leaves
more energy
for the
various functions
of the
headlight!

LUXOS B
Specific
instructions and
information
LUXOS B
creates a
homogenous field
of light
that is
up to
600% brighter
and 200%
wider than
required by
German road
traffic regulations.
ON/OFF switch
2
The LUXOS
B is
switched on
or off
using a
push button
on the
rear of
the headlight.
If the
headlight is
switched on,
a yellow
LED shines
inside
the switch.
If the
bicycle is
parked, the
switching status
is stored.
After
longer periods
of non-use
it may
take up
to five
seconds of
cycling for
the
switched-on headlight
to shine.
Standlight
LUXOS B
continues shining
when the
bicycle stands
still. The
technology:
During cycling,
part of
the dynamo
energy is
stored in
a capacitor.
When
standing still,
this energy
powers the
headlight’s LEDs
so that
the head
-
light continues
to shine
even if
the dynamo
supplies no
energy. Standlight
can be
deactivated prematurely
by pushing
the button.
Please note:
The
function
of interference-prone
wireless tachometers
may be
affected by
LED
headlights.
