USAGE INSTRUCTIONS
1 Press the switch at the end of the flashlight to turn
it on/off.
2 BL900 providesthree lighting options:
•Maximum brightness: 100% output.
•User-defined brightness: ten selectable modes
ranging from 10% to 100% output.
•Strobe / SOS modes: slow strobe, fast strobe, police
strobe andSOS.
3 Operation instruction:
To turn the BL900 on, briefly press the power switch.
The defaultsetting is maximum brightness (100%
output).
To access user-defined mode: withthe BL900 turned
on (in either max or user-defined mode), hold the
power switch down for more than 2 seconds and the
BL900 will cycle through 10 levels of output.
Whena desired output is displayed simply release the
button to set the brightness. (The brightness of user-
definedmode is memorable).
The BL900 has 4 hidden SOS / strobe modes.
To access any one of these modes, with the BL900
switched off, simply holddown the switch for 2
seconds and release.
To cycle to the next mode, once again hold the switch
for 2 seconds and release.
To exit strobe mode press the switch once briefly.
4 Battery indication:
The lamp’s switch is equipped with the three indicator
lights which blink in accordance with the battery’s
state of charge as described below:
•100%-75% charge: 3 indicator lights on
•75% - 50% charge: 2 indicator lights on
•50% - 25% charge: 1 indicator light on
•Below 25% charge: 1 indicator light is blinkingand
the brightness is automatically reduced to low
lumens (about 50 lumens).
5 Low battery shut off:
Whenthe battery capacity gets very low, the lamp will
shut of automatically. It should be recharged before
next use.

WARNINGS& TIPS
In order to avoid accidents, please pay attention to the following tips:
•Recharging is finished whenthe LED indicator turns to green.
•The battery pack remains at a normal temperature during recharging. If it gets unusual hot, do stop
recharging
•Do not dissemble the charger kit by yourselfifthe battery couldn’t be recharged.
•The battery can be used at any time once being recharged. If itis left unused for long periods, it should be
recharged for 6-8 hours every three months. After being charged they should be slightlydischarged for 10-20
minutes before storage.
•Be sure to always recharge the battery pack in a safe place and do not leave unattended while charging.
INTELLIGENT TEMPERATURE CONTROL INSTRUCTIONS
This product is designed with a temperature control circuit.
The LED is a heatingdevice that is sensitive to temperatures, especially high levels of power and brightness.
High temperatures will easily damage or shorten the life of the LED. Ferei designs its products with an intelligent
temperature-control circuit. It measures the temperature within the LED filament. As the structure of the lamp
differs, the thermal conductivity of the entire lamp is notthe same. In general, the constant surface temperature
of the lamp is 50ºC to 60ºC. When it exceeds its programmed temperature, itwill automatically reduce its power
to cool down , and the brightness decreases by small steps. After cooling-down (provided that battery voltage is
sufficient) the power with brightness increases again. The process of improving its brightness is relatively discrete
and will not produce a flashingeffect.
This stepping goes cyclically to maintain the user’s safety andthe light’s functionality. In conditions of good
air-cooling the lamp delivers light without stepping down even in high levels brightness mode. There are no
preset timers for stepping, but real-time active temperature measurements, So the actual runtime of the lamp
base on active temperature control to faster or slower battery discharge, may be slightlylonger or shorter runti-
me than the lamp of data provided.
MAINTENANCE
•Using a soft cloth clean the glass lens periodically to keepanefficient penetration (never use corrosive
cleanser).
•Keep water, dirt, sand and debris out ofthe cable connections and light body.
•Unplug the battery pack from the light when not in use to helpextend battery life.
•When riding in damp weather dry the light and battery immediatelyafter use.
WARNING
•It is a lighting tool, not a toy. Keep it away from children.
•It shouldnot be aimeddirectly at the eyes of humans or animals.
•Aim the beam down when riding on the road to avoid blinding oncoming vehicles.
•The lens andfront area of the light can get hot while in use. Avoid touching these areas.
•Do notdismantle the light or the battery pack, this will break the waterproof seal and void warranty.
•The BL900’s power source is a 7.4V lithium-ion battery pack coupledwith a protection circuit board. Should
the battery pack ever fail to charge or cease normal operation be sure to contact your local Ferei dealer and
under nocircumstances attempt self-repair.
•Dry the lights surface with a soft cloth after exposure to water or any corrosive substance.
