  • Page 3 PREFACE THE STRONG RADIANCE SPOTLIGHT is an AC follow spot complete with lamphouse, igniter, power supply, optical system, and color boomerang.

  • Page 5 Setting the tripod base to an extreme operating height contributes to making the spotlight assembly topheavy and unsteady. THE RADIANCE COLOR BOOMERANG mounts to the front of the unit on two studs (see Figure 6, Item 15) aligning to keyhole slots at the top of the housing, and is attached to the spotlight at the bottom of the housing by a thumbscrew.
  • Page 6 LAMP INSTALLATION AND OPERATION REMOVE THE REAR TOP COVER PLATE by releasing the four chromed captive quarter-turn screws and lifting the plate from the top of the lamphouse enclosure. Loosen the two thumbscrews (A) and dismount the stainless steel heat shield to expose the lamp socket (B & C). DO NOT TOUCH the quartz portion of the metal halide lamp with bare fingers!

  • Page 7 LAMP INSTALLATION AND OPERATION(continued) ONCE THE LAMP has reached full brightness, project a spot on a wall or similar vertical surface opposite the spotlight position. Loosen the two thumbscrews and remove the adjustment mechanism cover (F) from the back of the lamphouse to expose the lamp positioning controls. Positioning Focus Screw Lock Screw Focus Lock Screw LOOSEN THE TWO positioning lock screws to permit moving the entire mechanism on the back of the lamphouse.
  • Page 8 OPERATION OF OPTICAL SYSTEM THE SPOT SIZE CONTROL (ZOOM) is located on the right side of the optical system protruding from a slot in the spotlight housing. A variation of spot sizes from full flood to a small spot can be obtained by moving the zoom control from one extreme to the other. Beam intensity is increased by this optical system when reducing from flood to spot, and maximum intensity is reached when the zoom is in the extreme forward position. Depressing a thumb lever adjacent to the control permits free movement forward and back, and releasing the thumb lever locks the control in position. ROTATING THE ZOOM KNOB operates the spot focus control. When making an adjustment, rotate the focus control until the sharpest edge is obtained on the projected spot.
  • Page 9 OPERATION OF OPTICAL SYSTEM (continued) THE DISENGAGED, or fully open position of both masking shutter levers is to the extreme left (away from operating side). Varying degrees of masking, from fully open to complete cutoff, are obtained by moving the levers to the right (toward operating side) THE ANGLE OF THE MASKING SHUTTER BLADES can be adjusted to compensate for the horizontal and vertical projection angle. If the spotlight is installed at an extreme house-right or house-left position, the projected edges of the masking blades may not align horizontally with the apron, or vertically with the proscenium. Remove the top access covers to expose the horizontal (rear)
  • Page 10 The individual operator can set his or her desired degree of tension. OPERATION OF COLOR BOOMERANG SEE THE “SETTING UP SPOTLIGHT” SECTION in the preceding pages of this manual for details of the “Stowed” and “Deployed” configurations of the Radiance boomerang.

    MAINTENANCE REMOVABLE COVERS, secured with quarter-turn fasteners, are located above the lamphouse and optical system. To clean the lenses, remove the two front optical system top covers. The center lens, the back surface of the large lens, and the heat filter glass can be cleaned easily through this opening. Using a good grade of alcohol and piece of lens tissue (facial tissue can be used as a substitute), gently wipe both sides of each lens until the surfaces are clean.
