Overview

ETC combines the efficiency of the HPL lamp with the singularoptical qualities of the fresnel optical system to create the trulyadvanced ETC Source Four Fresnel. Traditional fresnel optics providea unique quality of blending wash light and beam shaping via barndoors for well-defined, soft-edged area lighting. The Source FourFresnel combines this classic system with a unique reflector designenabling the HPL 750W-equipped Source Four Fresnel to equal thelumen output of other 1000W fresnel fixtures. Spot-to-flood focusis accomplished by large, easy-to-use knob for quick adjustments ininconvenient positions. The unique Quick eXchange socket designpermits re-lamping from underneath the fixture without breakingfocus in most situations.
