With C. Webster Marsh & George Filtsos
3/14/22 – Lighting Episode 244 (Full Version) – C. Webster Marsh & George Filtsos 49:29
This one is truly for the lighting dorks! When it comes to value engineering, do we go with 0 – 10 volt analogue OR digital lighting controls? With Michael moderating, Webster and George have a spirited debate on the issue.
C. Webster Marsh is the owner of Penumbra Controls, where he brings 14 years of applied experience with lighting and controls, and he enjoys using his wealth of knowledge in the architectural lighting design industry.
George Filtsos started EcoGrid Technologies in 2019, and they have already helped companies save well over 14 million kWh of consumption. “What sets us apart in a big way is the advanced wireless controls, giving clients the best ROIs in the business.”

George is so rude, I don’t care what he sells, would never listen to someone so sarcastic and incredulous that everyone else in the lighting industry is stupid and backwards. His website doesn’t have any information. Lighting controls need more discussion, but this was awful.
Hi Sarah, thank you for your comments and we are sorry you didn’t enjoy George on the show. He has been a previous guest and is outspoken on what he believes in. We welcome that but also understand it comes with risks. As Greg and Michael say: “we don’t have listeners, only colleagues who don’t do podcasts!” We hope to continue to have your support.
