EA81 questions:
1.
batteries is 8 pcs in series conncetion.
the LED was show in 6 volts @3amps or 12v @1.5amps .
the R&D dept make a ajustment in the LED TO 6V @4.2amps . so total should be 25w .
Yes , the circuit would consume 12vlots , but for this model ,should be consume with 9.6volts
then it will show 25w .
2.
temperature of EA81
The ATR only active after one minute when the flashlight on .
so : turn on the flashlight , after one minute . ATR active ,when the head' temperature is over 55 degree . it will decrease the output .→_→ so the runtime will get longer
when it is less 55 degree , the flashlight will keep the temperation . →_→ the runtime will get shorter .
Now it is Autunm in China , termperation from 25degree -30degree in Guangzhou . and the whether in Germany must be much colder than Guangzhou,China .
The whether (the surrouding environment temperature ) also have an affect in the runtime
