The heart of the two lamps is the switch module which accommodates
the front and rear threaded covers.
The magnetic pressure switch which controls the electronics needs no
penetration of the housing. A Hall sensor measures the magnetic field
changes created by the movement of the switch.
These changes are then decoded and an illumination is produced that
is relative to the movement of the switch, (the more the switch is depressed,
the brighter the lamp illuminates).
The standard 20 watt HLX high power halogen Bulb is supplied with a
controlled over voltage. The Bulb effectively has more than a 30% increase
A discharge protection switches the lamp off and prevents the voltage
in the cells falling below 0.9 volts, before this occurs however, a
low capacity warning informs the user with 3 blinks of the halogen Bulb
of the imminent end of the burn time. The lamp can then be switched
over to a reduced power setting, thus extending the time before the
lamp turns itself off.
The switch also allows signals to be sent using the Morse alphabet.
It is also possible to activate the automatic SOS distress signal, (3
x short, 3 x long, 3 x short). The switch can be deactivated preventing
the lamp from inadvertently being turned on, for instance during transportation.
An automatic charger is supplied with each lamp, suitable for use with
either 115 or 230 volts.
The charger switches automatically over to a pulse trickle charge when
the cells are fully charged.
The state of charge is indicated by an LED signal.
The charging times are as follows:
mini ca. 6-7 hours
medi ca. 8-9 hours
An automatic rapid charger (off-shore I/6), with a charge time of between
2 and 4 hours is optionally available.
