The two lens zoom system is adjusted by the heat resistant knobs under the front of the unit between 21° to 36° hard edge, the soft edge range is greater. This beam can be precisely shaped by use of the four retained (but removable when the cut out is engaged into the side extrusion) shutter blades, which have heat-resisting handles for ease of use. Optional accessories include a drop-in iris and, for gobo projection (patterns), a rotatable gobo holder.
To give a "peaked" or "flat" beam, the lamp position is adjustable. The heat-resistant rear handle and the "T" shaped tilt locking handle give easy, cool control when adjusting the unit's position.
