Abstract
Certain aspects involve lighting systems in which an intensity can be selectively modified. For instance, a lighting system includes a light source and a programmable device. The programmable device is configured to detect an input resistance and cause a particular current to flow through the light source, thereby causing the light source to emit a particular lumen intensity corresponding to an input resistance.
