Litepanels has begun shipping their Sola ENG LED Fresnel model. Offering beam control of 10° to 70°, the daylight-balanced Solas provide the controllability and single-shadow properties inherent in a Fresnel light, but utilize just a fraction of the power of conventional fixtures. Employing a proprietary 7.62cm (3”) lens, it draws just 30 watts yet produces light output equivalent to a 250W tungsten (with 90% less power and a lot less heat).
I haven’t had a chance to try this one myself yet, but I’m told that, like all Litepanels, Sola ENG Fresnels feature instant dimming from 100% to 0 with no noticeable color shift. The SolaENG provides manual focus and dimming control via camera lens style ergonomic controls. Output is fully flicker free, and remains consistent even as the battery voltage goes down.
Designed for both on-camera and off-camera mounting, the SolaENG is 102mm x 102mm x 127mm (4” x 4” x 5”) and weighs just .28kg (10 ounces). The SolaENG runs on 10-20VDC sources such as camera batteries, or via an AC power adapter.
