Rushi Kumar, vice president of engineering at DMF Lighting, sat down in the VW Buzz podcast van to discuss how engineering, design and technology are converging to redefine modern lighting. Here, he traces his journey from Lutron to Crestron to DMF, sharing insights into how LED innovation, digital lighting and tunable technologies are enabling new levels of design precision and user experience.
Kumar also discusses how AI and intelligent control systems are shaping the next generation of smart lighting, balancing automation with simplicity for homeowners and integrators alike.
Inside the Podcast Van With Rushi Kumar
“As an engineer, you’re always thinking about why something is done a certain way and how to make it better,” Kumar begins. “The key is converting that into something people actually want — a useful product rather than just a cool piece of technology.”
He notes that while the transition from incandescent to LED lighting emerged as necessary for energy efficiency, it initially came at the expense of quality. DMF’s goal, he says, has been to bring back the warmth and visual comfort of incandescent lighting while taking advantage of what LEDs make possible — such as smaller apertures, tunable white technology and cohesive linear integration.
“With digital lighting, designers can now fine-tune every fixture, match color consistency across products and create truly personalized spaces,” Kumar explains.
He also highlights balancing sophistication with simplicity in lighting control. While the industry has embraced apps and advanced automation, he emphasizes that usability must remain central. “Lighting control should be simple,” emphasizes Kumar. “Anyone’s parent should be able to walk in and turn on the lights.”
Looking ahead, Kumar sees artificial intelligence as a valuable design assistant — helping integrators and designers streamline planning, commissioning and even anticipate customer behavior. “AI will make systems smarter and more responsive,” he states, “but it’s still about enabling comfort and control, not replacing human intent.”
