The Zoom Ellipsoidal shall be a purpose designed fixture for interior stage, studio and display
lighting applications. It shall be constructed from custom aluminum extrusions and die castings. All

matt charcoal color, electrostatically applied, baked on epoxy powder coat.
Each fixture is to be fitted with a heat resistant rear grab handle.
Four stainless steel shutters shall be fitted, located at the focal point of the optical system in a
spring tensioned gate assembly. The shutters will mask the beam and provide a crisp edge when
inserted. Each shutter is to have a heat resistant handle with two finger holes.
The Acclaim Axial shall have an ellipsoidal reflector, manufactured from 99.99% super pure
aluminum anodised and polished to provide a pure specular reflector.
The reflector shall be designed to allow the lamp position to be adjusted to provide a flat {2:1} beam
or peak {3:1} beam. This adjustment shall be possible without use of tools by adjusting a central
planetary gear and three lamp tilt adjustment screws.
The Acclaim Axial variable lenses shall be manufactured from high heat resistant polished
borosilicate glass mounted within a moulded holders which move captive along a custom extrusion.
The lenses are to move with a minimum of vibration and without metal to metal contact. The focus
fastening system is to be by simple maintenance free screw knobs located on the side of the lens
tube, near the bottom.
The lenses shall be available for cleaning by means of a side hinged bottom tray held closed with a
sprung ‘push in’ finger locking clip. The entire lens assembly shall be removable for cleaning without
tools by unlocking of the hinge after operation of the locking clip.
The Medium 18-34 lens assembly supplied shall be interchangeable with the Wide 24-44 lens
assembly quickly in this manner.
The fixture shall be designed for use with a 575 watt lamp using a G 9.5 (TP22) lamp socket. The
lamp socket shall be mounted within an aluminum die cast heat sink. The wiring is to be in a separate
compartment isolated from the reflector / lamp assembly by a further cast heat sink and air gaps.
Access to the lamp assembly shall be via two threaded finger bolts. Re-lamping shall be possible
without having to change the focus position of the fixture.
Suitable lamps for the unit shall be:
575W GLC 15,000 lumens 400hrs average life

When the lamp assembly is removed the mains power shall automatically be disconnected
ensuring that it is not possible to fit a lamp into a live socket.
Tilt adjustment shall be by means of a screw lock system secured by a hand sized insulated
“T” handle which also allows one hand adjustment. Base tension shall be generated by adjustment of
the locknut pivot mount.
