Three things to consider when specifying led products
- 1. THREE THINGS TO CONSIDER WHEN SPECIFYING LED PRODUCTS
- 2. 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.
- 3. CRI THE 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.
- 4. 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 Lumens
