PATASKALA, OH 43062
CATALOG NUMBER: CEM
LUMINAIRE: ONE 12" X 8" MOLDED IVORY PLASTIC SINGLE FACE EXIT SIGN WITH TWO
MOLDED IVORY PLASTIC SWIVEL HEAD ASSEMBLIES, EACH HEAD ASSEMBLY CONSISTS
OF: ONE CIRCUIT BOARD WITH 3 LEDS, CLEAR LINEAR PRISMATIC LENS WITH
CONCENTRIC CIRCULAR PERIMETER PRISMS AND ONE CONICAL OPTIC PER LED. LENS
PRISMS OUT AND LINEAR PRISMS PARALLEL WITH THE 0-DEGREE PLANE. BOTH
SWIVEL HEAD ASSEMBLIES AND ALL 6 INTERIOR LEDS FOR THE EXIT SIGN WERE ON
FOR THIS TEST. ONLY ONE LIGHT HEAD WAS MEASURED FOR LIGHT OUTPUT.
LAMPS: THREE WHITE LIGHT EMITTING DIODES (LEDS), VERTICAL BASE-UP POSITION.
MOUNTING: SURFACE
LED DRIVER: BLP PROPRIETARY
NOTE: DATA SHOWN IS ABSOLUTE FOR THE SAMPLE PROVIDED AT CLIENT REQUESTED
INPUT VOLTAGE (3.6VDC) TO THE DRIVER. DRIVER INFORMATION PROVIDED BY
CLIENT. FOR THIS TEST THE LIGHT HEAD WAS ORIENTED TO PLACE THE LEDS IN
THE VERTICAL BASE-UP POSITION (AIMED TOWARDS NADIR).
INPUT ELECTRICAL: 3.60 VOLTS, 1.65 WATTS, 0.459 AMPS
TEST PROCEDURE: IESNA LM-79-19
TEST DISTANCE = 20.0 FEET
AMBIENT: 24.2

If distances are feet, results are footcandles.
If distances are meters, results are lux.
Note: The candela values used to generate this diagram were obtained
by averaging the photometric data into a single plane.
