Constant Lumen Management
Enabled by the embedded nLight control, the GTL actively tracks its run-time and manages its light source such that constant lumen output is maintained over the
system life. Referred to as lumen management, this feature eliminates the energy waste created by the traditional practice of over-lighting.
