As I began writing this editorial, I received word of the passing of the legendary Robert Redford. One of the most iconic images from his storied career is his portrayal of aging baseball player Roy Hobbs in The Natural, rounding the bases beneath a shower of sparks after launching a light-shattering, pennant-clinching home run against the Pittsburgh Pirates. Director Barry Levinson’s slow-motion shots of Hobbs’ victory lap serve as a poignant reminder to pause and savor the moment.
In many ways, the IES Progress Report mirrors the spirit of sports: we celebrate the team (manufacturer/product) and the achievement (technology/approach) and then quickly shift our focus to the next goal. Each Progress Report marks a step on an ever-evolving scale of innovation. But perhaps it’s worth slowing down—without the exploding luminaires—to reflect not only on where the industry stands and where it’s headed but also on the remarkable progress made over decades.
“Beginning in January 2026, LD+A will enter a new phase of becoming—with a refreshed look, new voices, and themed issues that reflect the evolving landscape of lighting”
It’s also essential to recognize the invaluable contributions of the IES Progress Committee Members, whose dedication makes this report possible. Special thanks to committee member and IES Fellow John Green, who plays a vital role in helping LD+A collect and share the year’s accomplishments. With 43 years of work on the Progress Report, Green exemplifies the enduring commitment and impact of IES volunteers.
As we approach the final stretch of 2025, LD+A has celebrated its own milestones, with recognition from both Folio and TABPI (Trade, Association, Business Publications International) for editorial and design excellence. We hope this visibility continues to elevate the amazing projects and thought leaders shaping the lighting industry.
With a strong year nearing its close, it’s time for my annual “couch-hopping” exercise. (Not the nutty Tom Cruise variety—more introspection than acrobatics.) And while I’m on the couch, I’m reminded of a quote often attributed to Swiss psychologist Carl Jung: “I am not what happened to me, I am what I choose to become.”
Beginning in January 2026, LD+A will enter a new phase of becoming—with a refreshed look, new voices, and themed issues that reflect the evolving landscape of lighting. We hope you’ll continue to join us on the journey.
