Constant Lumen Management
Enabled by the embedded nLight control, the BLT 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.
