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.

How to Estimate Delivered Lumens in Emergency Mode
Use the formula below to estimate the delivered lumens in emergency mode
Delivered Lumens = 1.25 x P x LPW
P = Ouput power of emergency driver. P = 10W for E10WLCP option.
LPW = Lumen per watt rating of the luminaire. This information is available on
the ABL luminaire spec sheet. LPW = Lumen per watt rating of the luminaire. LPW
information available in Performance Data section.
