ETC Source 4 Fresnel Lanterns

ETC's new Source Four Fresnel brings you the soft-focus lighting and sparkle you love, with Source Four quality and efficiency. Lighting designers have long applied the romance of fresnel light -- the controlled blending washlight and soft beam you can only get from a fresnel. Now you have that singular light quality and effect, and more, in a genuine Source Four luminaire.

We've combined the best of our acclaimed Source Four HPL lamp technology with the unique optics of a traditional fresnel. And that means you can further streamline your inventory with a single light source - the HPL. ETC's Fresnel gives you the high-performance light output and energy savings of a Source Four and the lighting characteristics that only a fresnel optical system can provide. We've combined that classic system with a special ETC dichroic reflector design, enabling the HPL 750W Source Four Fresnel to equal or even surpass the light output of 1000W traditional fresnel fixtures.

With the Source Four Fresnel, you choose the lamp wattage that best suits your particular application and energy requirements - from 375W to 575W to 750W lamps. And when you need to re-lamp a Source Four Fresnel, ETC's smart new design makes your work easier than ever. Our innovative socket and access door let you change out the lamp from underneath the fixture -- without having to break focus -- saving on work, time and trouble.

It's a zoom to focus. With the Source Four Fresnel, you get that timeless fresnel light in a 21st-century fixture. ETC's innovative mechanical design has simplified the focusing for you. Whatever physically awkward spot you're working in, we make it easier for you to adjust the luminaire from spot to flood, with a full-sized zoom knob you can get a real grip on. We've also engineered the fixture-housing to virtually eliminate light leaks and minimize spillage.

Like all the Source Fours in your rig, the ETC Fresnel is made of ETC-quality die-cast aluminium.
