If we go way back to NAB 2011, Chimera was showing a prototype of a similar solution that never got off the ground.Īctive Diffusion was being touted as a flexible, electronically-controllable LCD screen that can be used with fluorescents or any other cool lights, like LEDs, Zylight’s Active Diffusion panel affixed to gel frames, or precisely-sized Chimera softboxes. In fact, even that wasn’t the first time something like this had been shown. You may well remember way back at NAB 2017, Zylight and Chimera partnered up to create what they were calling Active Diffusion. At least to my knowledge, this project never got off the ground. They went on to say that it was versatile enough to replace common flashlights, headlamps, and flexible stem lights with spot/flood toggling and the unique ability to magnetically fasten and charge from various accessories such as a flex arm or head strap.

According to the company, it was designed to replace all lighting tools that currently exist in the market. Two years ago LumenArc launched a crowdfunding campaign for PHOTON, a compact all-in-one utility light. LumenArc is a relatively new company that actually doesn’t sell any other products, at least that I can find. It is also going to be more expensive than buying a diffusion frame and diffusion. On the other hand, because this is a solid diffusion screen, it is going to be a lot heavier and not as easy to transport. On the one hand, it is nice to be able to alter the amount of diffusion quickly without needing to change the diffusion that you are using. This is certainly interesting technology that has its pros and cons. According to LumenArc, they will hold up in challenging weather conditions. The Active Diffusion frames are made out of high-grade aluminum, fiberglass, and scratch-resistant polycarbonate. Both Diffusion Panels are 1″ / 2.54 cm thick. The 24″ x 36″ version is a lot lighter because it doesn’t have a large yoke frame. The 24″ x 36″ version weighs 4.2 lbs / 1.9 kg. The LumenArc Active Diffusion 40″ x 40″ version weighs 13.1 lbs / 5.94 kg. It is nice that you can power the diffusion vis mains power as well as from a camera battery. LumenArc specifies that a 98Wh battery will power the Active Diffusion for up to 20 hours.

This comes with a detachable V-mount battery plate and a 10′ power cable and an additional 10′ cable that runs from the hand-held controller/power supply to the Active Diffusion panels. The LumenArc Active Diffusion needs to be run via a hand-held controller/power supply. LumenArc states that it is best to think of their diffusion as being comparable to LEE Filters Opal Frost Diffusion Filter or Hampshire Frost diffusion. 1.5 stops seems to be the current limitation for this type of technology. Essentially the light transmission loss is 8% when the Active Diffusion is set to 1% and 21% when it is set at 100%. The Active Diffusion allows you to dial in anywhere from 1/16 stop ~1% up to 1 1/2 stops 100%. The LumenArc Active Diffusion is available in two sizes, a 40″ x 40″ / 1.02m x 1.02m frame and a 24″ x 36″ / 60.96cm x 91.44cm frame.

The Active Diffusion technology emulates the full range of standard diffusion densities as well as allows you to dial in everything in between. Essentially it is a mid-sized diffusion frame that allows you to adjust the amount of diffusion electronically. The Lumen Arc Active Diffusion is an electronically adjustable light modifying system that was designed to simplify grip and lighting inventory.
