THREE THINGS TO CONSIDER WHEN SPECIFYING LED

PRODUCTS

COLOR TEMPERATURE

COLOR TEMPERATURE DESCRIBES THE TONE OF WHITE LIGHT AN LED PRODUCES. THIS IS EXPRESSED IN

DEGREES KELVIN. THE TYPICAL RANGE IS 2700K – 6000K.

THE LOWER THE COLOR TEMPERATURE THE CLOSER TO

INCANDESCENT LIGHT THE SOURCE IS, THE HIGHER THE NUMBER THE

CLOSER TO COOL DAYLIGHT.

CRITHE CRI OF A LIGHT SOURCE DESCRIBES HOW WELL IT RENDERS COLOR TO THE

HUMAN EYE. TRY TO IMAGINE THE SUN AT HIGH NOON ON A CLEAR DAY. THAT IS

PERFECT COLOR RENDERING.

WE EXPRESS COLOR RENDERING ON A SCALE OF 0-100. HALOGEN IS TYPICALLY 100, FLUORESCENT IS IN THE MID 80’S.

FOR LED PRODUCTS LOOK FOR A MINIMUM OF 80+ CRI, 90+ IS OPTIMAL.

DELIVERED LUMENS

LUMENS ARE A MEASUREMENT OF HOW MUCH LIGHT IS GENERATED BY A SOURCE.

DON’T IMAGINE A LIGHT BULB CASTING LIGHT ON A WALL. IMAGINE LOOKING

DIRECTLY AT THE LIGHT BULB. THOSE ARE LUMENS. WHEN A LIGHT SOURCE IS

PLACED ALL LIGHTING FIXTURES REDUCE THE EFFICIENCY OF A SOURCE (IMAGE A

BARE BULB VERSUS ONE IN A LAMP SHADE) DELIVERED LUMENS IS THE

MEASURE OF HOW MUCH LIGHT A FIXTURE ACTUALLY OUTPUTS. Initial Lumens Delivered
