Understanding the Lighting Facts


It seems everything these days from cereal boxes to new cars have product information that helps the consumer better understand what’s inside. Use this guide to help you understand the lighting facts on your new LED bulb.

Lumens are a measurement of brightness.  Watts are the amount of energy required to power the light bulb.  Light Appearance is the color of the light.  Cooler light looks more like sunlight; warmer light is friendly and inviting.  Light Appearance is measured in Kelvin.

To learn more about where and how to use your new bulbs; refer to the frequently asked questions below:

While many LED bulbs are dimmable, they do not dim in the same way as incandescent bulbs. Because LEDs consume such a low wattage, many traditional dimmers do not function with LEDs and those that do may function in a different way than with high wattage incandescent bulbs. When using an LED in a dimmable application, you may experience:

  • A smaller dimming range. An incandescent bulb has a dimmable range of 100%; an LED’s range is between 70% and 90%.
  • The bulb may not shut off completely, even on the lowest dim setting. Because of the low wattage consumed by an LED, the bulb may stay illuminated when the dimmer is completely off.
  • Flickering. LEDs may flicker when dimmed because of the small fluctuations in power on the line.
  • No change in color. As an LED is dimmed, they do not shift color. Traditional incandescent bulbs offer a soft fiery glow when dimmed; an LED remains the same color, its brightness is simply reduced. If you plan to use LEDs in a dimmable application, you may want to install a dimmer specifically for use with LEDs.

When trying to determine where to install an LED, take a look around your home to determine which lights are on most often – those are the lights that would benefit most from making the change to LED.

  • Entryway light fixture
  • Table/Floor Lamp
  • Central ceiling fixture
  • Hall light
  • Sconce

Yes, though the life of the bulb may be shortened. Traditional cans are well insulated. This is great news for your home and bad news for LEDs. An incandescent bulb emits heat from the bulb and out in to the living space; an LED emits heat from the back and up in to the insulated can, giving the heat nowhere to escape. This heat exposure can shorten the life of an LED bulb. If you are interested in using LEDs in your canned lighting, you may want to replace your cans with those designed for use with LEDsOne LED light bulb uses the same amount of energy as 18 incandescent light bulbs.
