LED Facts

The Department of Energy has established an LED lighting facts label program where LED lighting products can have a label on them describing the performance results of LED products according to industry standards. A similar idea is labels on food products that list the fat, carbohydrates, protein, etc., but in the case of lighting it allows someone to quickly understand the LED lighting product specifications. So what is on the label? What is the fat, carbohydrates and protein of an LED lighting product? Below is a list of what is on the label and what that tells you about the product.

  • Light Output (Lumens) - This tells you how much light a product delivers. This is a way to compare a product containing an LED light with a product containing an incandescent light or compact fluorescent light. To see how bright the lumens are in our lights, view our Brightness Comparison page.
  • Watts - How much power does it consume? In the past this was easy with incandescent light bulbs. For example, a 60-watt light bulb consumed 60 watts of power. An equivalent LED light bulb consuming 10 watts of power may put out the same amount of light as a 60-watt incandescent light bulb.
  • Lumens / Watt - This provides an idea of how efficient an LED lighting product is at converting electricity into light. The higher the number the better (i.e. the more efficient it is at converting electricity into light). LED lighting products are already extremely efficient in this category and advances are happening such that they will get even better in the future.
  • Light Color - The color temperature is important. For LED lighting products that produce white light, the products could range in color temperature from 2700K to 6000K. 2700K tends to be a warm white color sometimes seeming almost yellow and 6000K tends to be a cold white color almost with a tint of blue as it gets closer to 6000K. In the middle, for example 4000K, is a neutral white color that tends to be a solid white color. Warmer white colors, somewhere in the 2700K to 4000K color temperature range, are good for indoor applications and cooler white colors, somewhere in the 4500K to 5500K range, are good for outdoor applications.
