Abstract
A light management device comprising a protective light cap or cover is disclosed that provides for the blockage or allowance of designated wavelengths from being inadvertently being viewed by persons or being projected onto an external surface. The protective light cap or cover is pivotable connected to a lighting source to allow the cap to be positioned over the light source and moved away from the light source. The protective light cap is retained in an open position that allows the light source to be viewed, by one of a magnetic catch or a physical catch.
