Systems, devices and methods for illuminating sites (e.g., surgical sites) are provided. An illumination device (e.g., a surgical site light) includes a body (e.g., a plastic body) with a cross-sectional shape similar to an inward-facing asymmetrical C, and wherein the body is shaped to be placed proximal to a site (e.g., surgical site) and emit light onto the site from a plurality of directions while inhibiting the light from radiating away from the outside of the body.
