Denver’s foremost lighting designers examine the current status and upcoming trends in the region’s lighting market, including challenges and opportunities for the future.

  • Comparisons in designing in the Rocky Mountain region vs. other areas. Learn about the unique opportunities, and how we can cultivate and market regional designers to local projects.
  • Technologies Impacting Lighting Design – Smart fixtures, networked controls, and software-based communications are becoming prevalent and will become code required. How do you specify while remaining technically accurate to ensure proper installation?
  • The Business of Design - The region considers a project’s design aspect more of an add-on than a necessity. It’s a constant struggle with contractors setting budgets before design. How do you value or quote a budget on a project when costs/prices from manufacturers don’t align with contractors’ quotes? As many products come from overseas, how will tariffs affect project budget and design?
  • Growing the Next Generation – There’s a challenge in finding the next generation of designers for the region. What does the next generation need to know to be successful? Are today’s education programs providing the right tools and skills to succeed? How are they being supported and mentored by established designers to perpetuate a thriving industry and continually improve the effectiveness and efficiency of lighting designers everywhere?

Horton Lees Brogden Lighting

Katherine is inspired by the stories that set the tone for building design, and strives to capture what is unique about the architecture and the client when developing the lighting design. Katherine was drawn to lighting design because it represented a hybrid of creativity, problem solving and biological sciences — though it wasn’t her first choice of study. Originally slated to major in chemical engineering, with the intention of pursuing a career in manufacturing explosives, her perspective changed after taking an engineering class that introduced her to lighting. From that point on, she has fostered an ever-evolving appreciation for the impact that light can have on a space, and the emotional connection it can strike with occupants. Katherine has been building upon her experience by working on design projects in the corporate, healthcare and higher education market sectors. She brings a fresh and up-to-date perspective in the “light and health” debate, and is skilled in being able to craft a narrative of lighting design that weaves into the architectural design goals.
