The Cosine is a lighting design studio that treats light as a defining part of human experience, storytelling, and culture—not merely a utility. The studio partners with clients to shape spaces, emotions, and experiences through thoughtful lighting, considering each project’s architectural and brand context as well as its intended mood.

The Cosine manages the lighting process from concept through occupancy. Its services include an Illumination Session to align project goals and technical realities; concept development and calibration, including preliminary budgets and design refinements; and technical documentation with detailed drawings and specifications. The team also coordinates procurement and production, working with manufacturers and fabricators on pricing and delivery, and provides on-site support during construction to help ensure the design is realized as intended.

For clients seeking focused guidance, The Cosine offers retainer-based concierge services covering lighting-package reviews, specification improvements, and sourcing advice. Its portfolio includes projects such as Moonrise Way, West Loop Trading Office, Spacetime Floatation, Remedy Place Boston, and HUME.
