Compare
A display utility on the Mac you own.
Red Light Display adds timed sessions — including Morning Red and Low Light — and a desktop filter. It is not a dedicated panel and has not been shown to match that hardware’s dose or health outcomes.

A matching timer is not a matching dose.
The amount of light reaching a surface depends on its spectrum, output, distance, and angle. A larger screen or a similar session duration does not establish equivalent delivered energy, coverage, safety, or results. We do not claim parity with low-cost lamps or higher-output panels.
