THE “L” AND “B” VALUES INDICATE RESPECTIVELY THE PERCENTAGE OF RESIDUAL
FLOW AND THE PERCENTAGE OF LEDS THAT DO NOT RESPECT THE SPECIFICATION
IN THE TIME PERIOD INDICATED BY THE MANUFACTURER, CONSIDERING A
CONSTANT AMBIENT TEMPERATURE (AT) OF 25°C AND A CONTACT TEMPERATURE
(CT) OF 60°C. A LED DECLARED L70B10=223˙824 HOURS INDICATES THAT UPON
REACHING 223˙824 HOURS, 90% (B10) OF THE DIODES HAVE A RESIDUAL LUMINOUS
FLOW EQUAL TO OR GREATER THAN 70% OF THE INITIAL FLOW (L70).
