CRI ON OUTPUT
A solid-state light source that uses multiple arrays of “white” or RGB (red/blue/green) light emitting diodes as a low wattage, low temperature source. LED arrays cannot operate without a driver, a fixture, and a control. These components must all be compatible in order to ensure that their integrity is maintained. It is an extremely long-lived light source, which also produces very little heat on the object being illuminated.
MEANS OF INCORPORATING MULTIPLE LED’S INTO A PACKAGE WHICH CAN THEN BE MOUNTED ONTO A BOARD AND USED IN A LUMINAIRE
SIMILAR TO THE BALLAST IN A FLUORESCENT SYSTEM, RESPONSIBLE FOR CONVERTING AC POWER PROVIDED BY BUILDING TO DC POWER USED BY LED. REQUIRED FOR DIMMING & SWITCHING FUNCTIONS AND POTENTIAL WEAK LINK IN ANY SYSTEM

Many aspects of design that were previously
considered “nice to have” are now crucial
LED’s need to be controlled to work
Within the context of a game without rules our best
defense is to look at everything
More specificity is not always better, it might just be
more
