Years ago when you wanted to change a Lightbulb in one of your fixtures, you would go by the sticker that tells you the maximum wattage Lightbulb that can be used or just replaced it with the same wattage Lightbulb that was in there before. These days when we purchase an LED replacement, we are faced with different choices such as Lumens or Color Temperature and that can be confusing. Here are some things that might make things easier when replacing that Lightbulb or deciding on a new fixture.
Lumens: A “new” way of knowing how bright the LED bulb is. The higher the Lumens, the brighter the light. The equivalent wattage to a Conventional Lightbulb is usually shown on the packaging but sometimes not shown if you are purchasing an LED fixture. Here are some general guidelines:
Conventional 40w Lightbulb = 450 Lumens LED
Conventional 60w Lightbulb = 800 Lumens LED
Conventional 75w Lightbulb = 1,100 Lumens LED
Conventional 100w Lightbulb = 1,600 Lumens LED
Color Temperature: Measured in Kelvin (Example 2700K) is the measure of the lights color. Here are some examples:
2700K is a warm type of light and is most like a Conventional Lightbulb
3000K is a bright white type of light that is similar to the light you would see outside on a bright, sunny day
5000K is a cool type of light that is more blueish in color
CRI: Often overlooked, the Color Rendering Index measures the ability of the light to accurately reproduce the colors of the object it illuminates. The higher the CRI the better the light reflects the colors accurately, the lower the CRI the more unnatural the colors appear. Did you ever look at something such as a paint swatch in a store and when you took it home it looked different? This might be why. Here are some general guidelines:
A CRI of 80 is the general baseline of acceptable color rendering and is considered mid-range to low on the scale
A CRI of 90 and above are considered high CRI lights and work great for places such as Hospitals, Printing Facilities, Photography Studios and Retail where color appearance may be important
