Astera’s 1,000W output LeoFresnel light uses only 250W of power

May 31, 2023 by John Aldred Add Comment

Lighting manufacturer Astera has today announced their new series of Fresnel lights. They’re kicking off with the 300W PlutoFresnel and the larger 1,000W LeoFresnel. Astera says that the two lights are designed to “plug a significant gap in the market”. Essentially, they see a big gap in the LED lighting market and a distinct lack of LED Fresnels.

There are a number of Fresnel attachments on the market for standard COB LEDs, but very few dedicated Fresnel LED lights. The PlutoFresnel puts out the equivalent of a 300W light while drawing only 80W. The higher output LeoFresnel draws only 250W while putting out the equivalent of a 1,000W. Both lights also offer a wide range of full-spectrum colours thanks to their RGBMA LED makeup.

Litepanels launch new Studio X high-performance LED Fresnel range

Sep 10, 2022 by Alex Baker Add Comment

Litepanels have teamed up with Videndum to launch its brand new Studio X bi-colour Fresnel range. The range consists of high-quality, energy-efficient broadcasting lights that create a natural and balanced look on the subject. The fresnels are available in six models with lens sizes from five to fourteen inches. Each one offers a directional precision spot light to flood beam control of quality white light.

The natural-looking light creates perfect skin tones by using high output COB LEDs to produce superior white light. The lights are dimmable from 0-100% or across the adjustable CCT range from 2700°K to 6500°K. DIYP spoke to Andrew Woodfin to find out more.

This simple blackboard model explains how a Fresnel lens works

Apr 30, 2021 by John Aldred Add Comment

Fresnel lenses are found in all kinds of things from the lenses and light modifiers we use in photography and filmmaking to lighthouses that guide ships at sea. The lens was developed by French physicist Augustin-Jean Fresnel, after whom it was named, specifically for use in lighthouses. It allows for the construction of huge aperture and short focal length lenses but using less material than more traditional lens optics.

How exactly do they work, though? In the video above, David Willey explains how a Fresnel lens functions and why it is the shape that it is using a simple blackboard model and some magnetic strips. But essentially, Fresnel lenses are just regular lenses with big chunks taken out of them.

The Nanlite Forza 500 could be an Aputure 600D killer

Sep 25, 2019 by John Aldred Add Comment

At IBC 2019, Aputure had only just announced their new 600D LED light. But already it looks to have some serious competition in the form of Nanlite’s Forza 500. We visited the Nanlite stand to find out more about it, and to check out their new, massive, 10″ Fresnel modifier for it.
