[LUMINAIRE] MOLDED IVORY PLASTIC HOUSING, TWO MOLDED IVORY PLASTIC SWIVEL HEAD ASSEMBLIES, EACH HEAD ASSEMBLY CONSISTS OF: EXTRUDED FINNED METAL HEAT SINK, ONE WHITE CIRCUIT BOARD WITH 12 LEDS, CLEAR MICRO-PRISMATIC PLASTIC LENS WITH ONE OPTIC PER LED. BOTH SWIVEL HEAD ASSEMBLIES WERE ILLUMINATED FOR THIS TEST. ONLY ONE LIGHT HEAD WAS MEASURED FOR LIGHT OUTPUT.
[LAMP] TWELVE WHITE LIGHT EMITTING DIODES (LEDS), VERTICAL BASE-UP POSITION. INPUT VOLTAGE (9.6VDC) TO THE DRIVER. THE SWIVEL HEAD ASSEMBLY WAS SET IN A CLIENT REQUESTED POSITION WHICH IS CANTED APPROXIMATELY 20-DEGREES FROM STRAIGHT AHEAD WHEN LUMINAIRE IS IN THE VERTICAL AND LEVEL POSITION. FOR THIS TEST THE LUMINAIRE WAS POSITIONED TO PLACE THE LEDS IN THE VERTICAL BASE-UP POSITION (AIMED TOWARDS NADIR). WITH THE DRIVER OPERATED AT 9.6VDC TO THE BATTERY INPUT. IN ORDER TO DETERMINE EFFICACY, THE INPUT WATTAGE TO THE DRIVER OPERATING BOTH LIGHT HEADS WAS DIVIDED BY 2 TO REPRESENT A SINGLE LIGHT HEAD INPUT WATTAGE. THE SYSTEM EFFICACY WAS THEN CALCULATED BY DIVIDING THE LUMENS OF A SINGLE LIGHT HEAD BY THE CALCULATED INPUT WATTAGE FOR A SINGLE LIGHT HEAD.
