A light fixture may include one or more light sources and one or more lenses for manipulating light provided by the light sources. The lenses may manipulate the direction of the light, light wavelength, dispersion pattern, or any other quality of the light. The lenses may be slidably removable from the light fixture to provide for easy exchange of one lens for another. This exchange of one lens for another may provide for rapid and easy changes to the light dispersion from the light fixture without requiring manipulation of the light sources themselves, especially in the case of exchanging a first lens with a first quality for a second lens with a second, different quality. In addition, a method of servicing the light fixture may include the provision of alternate lenses based on predetermined factors such as time, light degradation, environment of use, and the occurrence of specified events. |
