Bradley D. Schlesselman

Brad is responsible for various lighting and vision research projects at Musco Lighting in Oskaloosa, Iowa. He began his lighting career as a Lighting Designer for Musco in 1998 and became Lighting Certified (LC) in 2001. During his time at Musco, he has completed lighting designs for thousands of athletic fields, ranging from recreational to professional venues.
In 2012, Brad became a Senior Research Engineer engaged with vision research on the Intrinsically Photosensitive Retinal Ganglion Cells (IPRGC)/melanopsin receptors and their role on perceived brightness. He has conducted numerous speaking engagements for the lighting industry and is currently the Chair of the Discomfort Glare in Outdoor Nighttime Environments (DGONE) Committee. He is also a member of several other IES Committees, including the Outdoor Nighttime Environments (ONE) Committee.
As senior research engineer with Musco Lighting, Brad has worked closely with DarkSky International for many years helping to establish benchmarks and best practices for exterior lighting that align with DarkSky’s purpose and goals. Brad has helped Musco’s decades-long mission of controlling and applying light in ways that significantly reduce glare, spill, and sky glow through educational sessions. He is a firm believer that the best outdoor lighting systems are designed in a way that’s equally focused on preserving darkness as on illuminating the intended area. Lighting at night, when necessary, can co-exist with protecting the enjoyment of observing the dark nighttime skies.
