April 23, 2010 Active Diffusion ? April 23, 2010/ Bennett Cain Active Diffusion? Sorry to be a re-posting maniac today but this is just awesome... If you read this site, you probably follow The C47 as well so you've already seen this but thanks to Jem for sharing and allowing the vid to be embedded. I can't believe no one else who was doing video coverage at the show featured the Active Diffusion. Why is this a film/video lighting product? The household and business applications seem tremendous. I'd love to have this stuff on every window in my apartment! $400 for the 2x2 piece is very affordable. I wonder how durable this stuff is though.. I heard you can't put a hot head behind it, cool sources like LED's and Fluorescents only at this time. ZYLIGHT
