Source Four PAR

From Wikipedia, the free encyclopedia

ETC Source 4 PAR is intended to be a replacement for PAR cans. The Source 4 PAR uses an HPL lamp, which is the same used in other ETC instruments, and allows for changing the beam spread by using 5 interchangeable lenses. The HPL lamp combined with modern enhanced aluminum reflector technology allows for more light output while using lower wattage. A 575 watt HPL lamp will put out light comparable to a 1000 watt PAR 64, and the Source 4 PAR is rated up to 750 watts. Their size is also an advantage. They use a six inch lens compared to a PAR 64, which is eight inches wide. They also do not have a long barrel as many PAR cans do. This saves space and cost of color filters.

[edit] Source Four PARNel

A variation of the Source 4 PAR is the Source Four PARNel, meant to be an alternative for fresnel lanterns. The PARNel can be focused from flood to spot using a knob on the casing which rotates the lense instead of moving the lamp and reflector assemblies which is necessary for fresnel lanterns, and can be focused to a wider angle then standard fresnels. The PARNel also uses the enhanced aluminum reflector technology, and at 575 watts puts out more light than a standard 1000 watt fresnel lantern.
