A Fresnel Lens On An LED Light?
Bruce A Johnson | 04/13
You Want To Know What Litepanels Is Thinking

You can’t swing a dead cat here at NAB without hitting LED lighting. What was an emerging trend last year is a full-fledged phenomenon this year. But 99% of the lights have one thing in common: They are open-faced - unless you are visiting the Litepanels booth.
What you are looking at is the prototype of the Litepanels Sola6 fresnel light. It has roughly the same brightness as a 650-watt tungsten light, but emulates the 5600 degree daylight Kelvin color of an HMI. Power consumption? A measly 75 watts!

The Sola lights control beam spread the same way conventional lights do - by racking the light bulb back and forth behind the lens. But while most lights do this manually, the Sola lights are all electronic, with a servomotor controlled by an LCD touchpanel instead of a knob. The same panel can control brightness as well. And it goes without saying that these lights have almost no heat generation - in fact, many of the structural parts are plastic.
In addition to the Sola6, the line includes the Sola 12, which is roughly as bright as a 2000W tungsten lamp (with 250w consumption) and the SolaENG, a 250watt equivalent camera-top light (30w draw) with a remarkable focal range and throw. When available, the Sola 6 will have a list price in the $2600 range, the Sola 12 around $5800, and the SolaENG around $650. More info at www.litepanels.com.

That sounds like a pretty great lineup. I love the sound of a 650w fresnel with a 75w draw.
I’m pretty leery of servo-controlled focus, though. Call me old fashioned, but it just seems silly to do electronically what you could do mechanically.
Would be nice to see a “studio version” with electronic focus control (I’m assuming you can control that with a board…), and a more rugged, mechanical “locations version” available.
