Theory of Operation
The Maxa Beam Searchlights produce light by passing an arc of electricity between two electrodes in a
quartz tube filled with a pressurized atmosphere of Xenon gas. An extremely precise plasma ball is formed
and precisely positioned within an electroformed reflector by an internal microprocessor controlling a servo
motor.
When the ignition button is momentarily pressed a high voltage R.F. igniter produces up to 20,000 volts to
ionize the Xenon gas within the lamp, allowing the 12.5 to 14 vdc operating voltage to bridge the arc gap
and form a steady state. Once the arc is established, gas temperature and pressure start to climb, forcing the
Xenon into a plasma state. The light will come on with a constant high beam for approximately 3 seconds
to assure reliable ignition of a cold lamp and will then go to the programed intensity and mode. After
ignition of the lamp is completed, the internal microprocessor takes control of the operation of the
electronic focus, power settings and the user programmable options.
The searchlight contains no internal, user serviceable parts. The switch mode power supply is factory set
and requires no adjustment, even after a lamp change has occurred as the control circuitry is self calibrating.
Internal power regulation keeps both the intensity and color of the beam constant as the voltage from the
battery drops.
Warnings
Do not operate this light in an explosive environment.
Do not look directly into the light at close distances.
Do not immerse the Maxa Beam in water or allow water to enter the case. While the Maxa Beam
is weather resistant, submersion in water will cause permanent damage to the light.
Do not operate the searchlight if the front lens is damaged or removed.
Do not allow the concentrated beam of light to be focused on flammable materials at close
distances for prolonged periods of time.
Do not touch the Xenon lamp connections during operation or ignition as high voltage is
present.
Do not touch the clear portion of the Xenon lamp. If the lamp is accidentally touched, clean with
the solution supplied in the replacement lamp kit or alcohol.
Always wear protective eye wear if removing the front lens cover. The lamp is under positive
pressure and should be handled with care.
To prevent accidental activation of the searchlight, always disconnect it from the power cord
when it is not in use, placed in storage or being transported.
