5-2. Specification Descriptions
5-2-1. Brightness
The brightness depends on the ambient temperature. The light may be dim if the ambient temperature is
extremely low.
5-2-2. Continuous operating time
Continuous operating time means the continuous lighting time when using a fully charged battery. It varies in
accordance with the frequency of use, battery capacity and other factors. Accordingly, the continuous operating
time values in the above table are intended for reference purposes only.
When using the EB 9M or EB 12M battery in the Model UB 12DL, the remaining power indicator cannot show the
correct status. This is an unavoidable phenomenon caused by the characteristics of the circuit incorporated in the
EB 9M and EB 12M batteries, and is not a failure of the battery. There is no problem in using the EB 9M and
EB 12M batteries except that the remaining power is not shown correctly. The remaining power indicator is
restored by recharging the battery until the pilot lamp on the charger shows complete charging.
When using a Ni-MH battery:
If the Model UB 12DL is left for a long time with the switch turned on, it may adversely affect the Ni-MH battery
such as decrease in the charging capacity and the service life because the Ni-MH battery may be over-
discharged. Always turn the switch off when not in use.
