RAD/01
PREFACE
THE STRONG RADIANCE SPOTLIGHT is an AC follow spot complete with
lamphouse, igniter, power supply, optical system, and color boomerang. The light source is a 850 watt
DC double-ended metal halide lamp. Lamps are not supplied with the unit, but are readily available
from theatrical supply distributors.
AN ELLIPTICAL REFLECTOR is designed to operate in a fixed position with the
lamp mounted horizontally in the lamphouse. The lamp socket is adjustable in relation to the optics to
permit positioning the arc to the optical center line of the reflector. The igniter is contained within the
lamphouse enclosure.
THE POWER SUPPLY mounts below the lamphouse and comes equipped with a three-
wire AC line cord that connects to a 115 volt, single phase 60 Hertz AC line. A 230 volt, 50 Hertz
export model is also available. The power supply is protected by a 15 ampere fuse, and operation of
the power supply is controlled by the ON/OFF toggle switch on the lamphead.
ADJUSTMENT CONTROLS for positioning the metal halide lamp are located below
a cover at the rear of the lamphouse. This control mechanism permits concise positioning of the lamp
in relation to the reflector and also allows the lamp to be centered both vertically and horizontally on
the optical center of the reflector.
AN INTERNALLY WIRED FAN is used in the followspot lamphouse and operates
from the AC control circuit. This blower is wired through a time delay relay to permit the lamp to reach
full intensity more quickly. A thermal switch will interrupt operation of the spotlight if the fan fails to
move enough air to adequately cool the lamphouse.
NOTICE
The metal halide lamp contains mercury and expired
lamps should not be discarded in an ordinary refuse
container. Conform to local Hazardous Materials
ordinances or refer to www.lamprecycle.org.
