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.
2GTL 2 33L LP835, 3399 delivered lumens, test no. ISF 36873P6, tested in accordance to IESNA LM-79.

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.
