A test enclosure I built for a physician client during 2020. It was intended for studying how light-source distance and exposure time affected disinfection: internal pegs supported a platform at different heights, and a timer controlled how long the lamps stayed on. The photographs show ordinary fluorescent lamps fitted for demonstration, rather than UVC lamps.

The enclosure opened to show the interior and its adjustable platform supports. The different support positions let the client change the sample's distance from the light source for experimental comparisons.

The open enclosure with its lamps illuminated. These are fluorescent demonstration lamps, showing the physical arrangement of the light sources and test space. The box was built as an experimental fixture for the client's disinfection research.

The lamp assembly lifted away from the enclosure. I made the box and the lid-mounted lights as two separable parts, allowing access to the test space and the lighting hardware.
