The luminaire shall be a 1200 watt follow spotlight designed only for a 1200-HB metal halide lamp. A 1200 HMI lamp can
be substituted with reduced output. A single lever variable focus optical system using a galvanized steel cable linkage shall be employed; ribbons or cams shall not be acceptable. A gate assembly consisting of a nichrome steel heavy duty iris, paired  stainless steel trim shutters, gobo slot and heavy duty fading shutter shall be provided. Focus shall be via an external knob. Optical grade white water plate glass lenses only shall be used. Plastic or green lenses shall not be acceptable. The spotlight housing shall be extruded aluminum and sheet steel finished in black and gray epoxy powder-coated wrinkle finish. A six color automatic self-cancelling color boomerang shall be provided. Field control and "x" and "y" axes shall be external; internal controls shall not be acceptable. Lamp mounting shall be of the shock mount type. A safety switch shall be fitted to the lamp house top.
Power to the spotlight shall be controlled via two push buttons mounted in the spotlight head. Removal of the lamp house top or loss of power shall render thespotlight in the "off" mode. Replacement of the top or reinstating power will not unexpectedly relight the lamp. To restrike the lamp will require a momentary push of
the "on" button. The spotlight is supplied  with a silvered glass reflector. An  operations unit containing the unit's electronics is quickly accessible from the bottom of the spotlight head. A quick release multipin connector shall be mounted on the bottom of the spotlight for  connection to the remote ballast unit. The ballast chassis shall have a 20 amp. circuit breaker, be constructed of extruded aluminum with stamped side and end parts, and may be operated in an upright or horizontal position or stacked in multiples. The unit shall include an elapsed time meter. The yoke shall be part of the head and allow for a maximum tilt of 55 degrees below horizontal and 50 degrees above horizontal. A stable three legged, folding base with locking casters and leveling jacks shall be provided. The spotlight shall be fan cooled. Housing dimensions shall not exceed 48"(L) x 17"(W) x 19"(H) including all controls. Net weight of the spotlight head shall not exceed 86 lbs. and 41 lbs. for the base. Current draw at 120 VAC shall not exceed 15 amps. Photometric data shall conform to the table provided. The luminaire shall be a Lycian Stage Lighting SuperStar 1.2 Model 1275.

The luminaire shall be a 400 watt follow spotlight designed to accept only an HTI-400/24 metal halide lamp. The field diameter of the beam shall be continuously variable from the narrowest head spot to the widest flood by means of a nichrome steel iris which shall be operable by an external insulated, offset lever known as the spot size controller. Units that iris down without increase of light output shall not be acceptable. The spot size controller shall be capable of being mechanically coupled or decoupled from the zoom focus mechanism by means of an externally located insulated know with pointer and escutcheon plate. In the coupled position the unit shall operate such that as the field diameter is decreased the intensity is increased. The luminaire shall incorporate an externally operable, continuously variable,calibrated peak/flat field adjustment. The optical train shall contain one specially coated optic and two crystal clear white water plate glass lenses plastic lenses shall not be acceptable. Relamping shall be accomplished by releasing the 1/4 turn fastener opening the rear lamphouse access door. Relamping shall be accomplished in less  than thirty seconds without the use of tools and without disturbing the prefocused lamp
alignment. The lamp shall be alignable in both the vertical and horizontal planes via two clearl labeled adjustment screws. The luminaire shall
be provided with elapsed time meter, on/off switch, and circuit breaker; fuses shall not be acceptable. These components, as well as two of the three fans, igniter, power supply, and a line cord with free end terminated in a NEMA-5-15P (15 ampere parallel blade U-round male) connector shall be contained within a power assembly tray. The power supply assembly tray shall be constructed of 20 gauge cold rolled steel with cast aluminum end plates, shall underhang the lamphouse, and shall be field changeable in less than three minutes. The luminaire shall incorporate an automatic, selfcancelling, seven color boomerang which shall  be quickly and fully removable, and shall feature self-captive match plates for each of the seven frames. A smoothly operating douser with dual controls allowing operation from both the side and rear of the luminaire shall be provided. An igniter and regulated type power supply shall be of domestic manufacture and approved by the lamp manufacturer. The power supply shall be externally controllable via switch and its operation shall be observable on a calibrated "wattwatch" meter. This will allow matching light output when two or more SuperArc 400s are used at one time. Non-regulated or "sealed" power supplies shall not be acceptable. The yoke shall be part of the head and allow for maximum tilt of seventy degrees below the horizontal; fifty degrees above the horizontal. The base shall be of the three-legged, folding type and include swivel casters and leveling jacks. Current draw at 120 volts A/C shall not exceed 10 amperes. Housing shall be of extruded aluminum and cold rolled sheet steel. Housing dimensions shall not exceed 50"(L) x 15"(W) x 17"(H). Net weight of the housing shall not exceed 101 lbs.; 41 lbs.; for the base. Photometric data shall conform to the table provided. The luminaire shall be a Lycian Stage Lighting SuperArc 400 Model 1267.
