Fresnel Series

GENERAL INFORMATION

ETC combines the efﬁciency of the HPL lamp with the singular

optical qualities of the fresnel optical system to create the truly

advanced ETC Source Four Fresnel. Traditional fresnel optics provide

a unique quality of blending wash light and beam shaping via barn

doors for well-deﬁned, soft-edged area lighting. The Source Four

Fresnel combines this classic system with a unique reﬂector design

enabling the HPL 750W-equipped Source Four Fresnel to equal the

lumen output of other 1000W fresnel ﬁxtures. Spot-to-ﬂood focus

is accomplished by large, easy-to-use knob for quick adjustments in

inconvenient positions. The unique Quick eXchange socket design

permits re-lamping from underneath the ﬁxture without breaking

focus in most situations.

ETC® Fresnel Series PHOTOMETRICS Photometric data below is measured with an HPL 750W/115V 300 hr lamp. To convert data when using any other HPL lamp, use the lumen or candela multiplying factors (Lm MF or Cd MF) for that specific lamp. These multiplying factors are listed in the Lamps table in this datasheet. For lumen data, multiply by the Lm MF. For candela or footcandle data, multiply by the Cd MF.
