1 Features Of Product
EH1 is perfectly created with electronic design, software design, production craft design
and user-friendly design. It applies the most advanced technology of the LED light source
and high-capacity li-ion battery technology to create a brighter and lighter multi-purpose
portable explosion-protected lamp. Our product is a kind of ideal lighting equipment for
mining using, industry using, also used for outdoor activity, riding lighting and other many
other practical purposes.
1.1 100000 Hours Lifespan and Super Stable Brightness
The product applies the most advanced American CREE LED light source and advanced
drive PCB, which promises its life span up to 100000 hours in certain condition. The well-
designed reector reduces the light absorption, which greatly improves the brightness.
1.2 Light in Weight
EH1 is designed to be super light and the EH1S is only 149g, which is half weight of the
normal lamps.
1.3 Safe, reliable, maintenance-free and antistatic
The Li-ion battery of EH1 is maintenance-free. Moreover, the battery protecting PCB
can protect the battery from overcharge, over discharge, over current, and short circuit
so that the battery won’t explode or burn. Therefore, the safety and reliability of EH1
are well guaranteed. Meanwhile, the enclosure material has a character of antistatic
electricity.
1.4 Impact-resistance
The shell of EH1 is made of bulletproof PC. The optimized mold design not only
strengthens the hardness of the shell but also lessens the internal stress, which makes
EH1 stronger in impact resistance and more durable in life span.

4 User Guide
4.1 Charging
Please select the NCR01 charger for EH light series which have accurate output
voltage and over current protection.
Connect the charger NCR01 with AC 100-240V to AC socket or DC 12V to the DC
input socket, and the charger indicator will be turned on. Put the EH1 light into
charger to start charging.
4.2 Charging Indication
EH1 has specialized charging indicators. One of the red charging indicators will ash
during the charging process. The number of red lights indicates the current power level.
When the EH1 is fully charged, all the red lights will glow constantly. During the charging
process, the rst ashing red light indicates the power level of about 25%; the second,
about 50%; the third, about 75%; while the fourth, about 100%. When fully charged, all
the red lights will be turned on constantly.

4.3 Switch On/O
• When the light is o, short press the switch button to turn on the light and access
HIGH. Short press the switch button repeatedly to reduce brightness to MEDIUM, LOW
and to turn o.
•
When the light is o, long press the switch button for over 3s to access Constant Red
Light. In this status, short press the switch button to access Flashing Red Light. Then
short press the switch button again to turn o the light.
• When the light is on, long press the switch button for over 1s to access SOS. In this
status, short press the switch button to access BEACON. Then short press the switch
button again to turn o the light.
4.4 Power Indication
When the light is o, long press the switch button for over 1s to access power indication.
The red lights will be turned on for 3s to indicate the current power level before going o.

6 Notes
1. EH1 is half charged before delivery, please fully charge it before using.
2. If the lamps are not used for a long period, please repeat the following maintenance
steps every two months: Fully charged →completely discharged→charged for 2hour.
3. When battery damage, function failure. Don't need to replace the battery, direct
replacement of new products.
4. Products using the environment is higher than the 2 category of pollution.
5. Do not charge in the explosive atmospheres. The output voltage of charge is 5V
(5V+0.5V max), open circuit voltage is 5V (5V +0.5V max).
6. Do not open the product in the explosive environment.
7. All the elements in associated with intrinsically safe meet the requirements of safety
components and do not cause the hot surface ignition and spark ignition.
