Theory of Operation:
The Maxa Beam Searchlight produces 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 RF igniter produces up to 20,000
volts to ionize the Xenon gas within the lamp, allowing 12.5 to 14VDC 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
programmed intensity and mode. After ignition of the lamp is complete, 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 light in water allowing water to enter the case. While the Maxa
Beam is weather resistant, submersion 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 alcohol or the solution supplied in the replacement lamp kit.
Always wear protective eyewear if removing the front lens cover. The lamp is under
positive pressure and should be handled with care.
To prevent accidental activation of the light, always disconnect it from the power cord
when it is not in use, placed in storage or being transported.
