Technical description:
1.Battery (Lithium ion)
It adpots new lithium ion battery which is with protection of over-charging , over-discharging and a short circuit. Every battery cycling lifetime is more than 500 times.It also have 80% rated capacity after being used 500 times.Its the latest environmental protection battery.
 
2. LED:it adpots 1W high-power LED. The life span is more than 50000 hours.Illumiance is more than 3000 lux/60lm. It adpost two working patterns: main light functioning only or six auxiliary lights funtioning together. When the main light fails to work, please switch to auxiliary lights( Warining: ask professionals to fix the lamp and go to safe places if one light source can't work).
 
3. Charger(Lithium ion):
It adpots isopiestic pressure current limiting charging way. Its volatge is 4.2V(normal charging voltage is 4.2V).When charging current is 1A and voltage approachs 4.2V, charging current will reduce gently.When batterys voltage is 4.2V and current is less than 1A, the indicator light will turn green. It means that miners lamp can work normally. When it is charging ,the indicator light will turn red.
