Abstract: Sealed LED lighting fixtures operated under certain conditions (e.g., outdoors, in cold ambient environments, at high operating current, and/or in non-hermetic environments) will oftentimes exhibit condensation on an inner surface of the emitting face of the fixture. When occurring, said condensation impairs the ability to produce useful light—namely, light harnessed and directed in a manner so to provide lighting for a task (or otherwise desired)—by diffusing light emitted from the lighting fixture. Envisioned are apparatus, methods, and systems to reduce moisture in sealed LED lighting fixtures so to reduce or eliminate condensation, and in a manner that addresses both fixtures already in the field and those being assembled in a factory setting. In one form, a carrier embedded with desiccant is positionally mounted inside the fixture in a desired position which has no or minimal impact on light output from the fixture.
