Lost cost ,high safety.

1. LED : less energy and super brightness LED

2. Battery : safety lithium ion battery

3. Small in size, light in weight, free maintenance, explosion prevention, waterproof, long life

4. Lighting time : more than 13 working hours, double light source design

5. Charger AC input : AC110 ~ 240V, 50/60Hz DC output : DC4.2V,1A

6. Working temperature : -10 ~ 45 degrees

7. Relative air humidity : <= 95% +- 3RH

Technical specification:1. Battery (Lithium ion)

It adpot new styled lithium ion battery which is with over-charging , over-discharging and a short circuit protection fuction.Every battery cycled lifetime is more than 500 times.It has 75% rated capacity after using 500 times.Its a newest environmental protection battery.

2.  LED:it adpot 1W high-power Led,The life is more than 50000 hours.illumiance is more than 1200 lux/30lm,it adpot two sets of light source,one is main - six auxiliary light source or main-axiliary in one .when main light source lose function,pls turn a switch axis into auxiliary light source then it go into work normally(This is for meet an emergency)

3.  Charger(Lithium ion):

It adpot isopiestic pressure current limiting charging way.Its setting value volatge is 4.2V(normal charging voltage is 4.2V).

When charging max current is 1A and voltage approachs to 4.2V,charging current will reduce gently.When batterys voltage is 4.2V and current is less than 100A,the indicator light will display green color.this mean that miners lamp can be used normally.When its charging ,the indicator light will display red color.
