52 CHAPTER 3 Light fixtures: The basic tungsten arsenal Axially mounted par fixtures The highest-wattage PAR lamp is 1200 W. It wasn't until several years into the new millennium that Mole-Richardson started using axially mounted tungsten lamps (specially designed by GE) in a fix- ture with a parabolic reflector. Mole calls these lights Tungsten Pars (Figure 3.23A). This design finally enabled wattages of 2000, 5000, and 12,000 W for incandescent parabolic reflector lights. The 12k par is comparable in light output to a 20k Fresnel, but uses 60% less power, and produces 60% as much heat. With the Tungsten Par, the lenses are fitted to the front of the fixture and can be changed at will. The lights have four available lenses, narrow, medium, wide, and extra-wide. These fixtures also allow for adjustment of the lamp in the reflector. This is not really flood-spot control. It is used to fine-tune the evenness and brightness of the beam. Accessories include scrims and barn doors. ETC makes an extremely efficient axially mounted par lamp called the Source Four Par (Figure 3.23B). Using ETC's renowned HPL lamp technology this light can achieve, with a 575-W lamp, light output comparable to a 1000-W PAR 64. If you use the 750 W lamp, the output is superior to any 1k PAR lamp. The 3250-K color temperature lamps come in sizes of 750, 575, and 375 W. The lamps also come in a 3050-K long-life version with four times the lamp life (1500-2000 hours as apposed to 300-400 hours for the 3250 K lamps). Lenses include VNSP, NSP, MFL, WFL, and an optional XWFL. Optional accessories include top hat snoot (gel extender), concentric ring snoot, and barn doors.
