When considering the use of LED lighting there are four main things that you need to know in order to make an informed decision. They are the following:

Color or Correlated Color Temperature is measured in Kelvins. Temperature, in this case, is not referencing the actual temperature of the bulb but instead the color that is being produced. Therefore, the lower the number, the warmer it looks and vice-versa. Learn more about color temperature!

Lumens: It is very important to know that lumens represent the amount of light that is given off. Traditional incandescent bulbs are measured in watts which represent the amount of energy consumed. This has caused a lot of confusion because LED's are measured in lumens.  Below is a comparison chart to further breakdown the difference.

Bases: Bases are the LED Bulb’s first point of contact and are responsible for receiving power from the source. They are also important because they keep the bulb connected to the power source.  Here is a list of the most common bases for LED bulbs. How do I know which LED light bulb I need?

Drivers: Pairing the appropriate driver with its respective bulb is very important. A failure to do so could cause Underdriving or Overdriving.

  • Underdriving – This is when the driver is not administering enough power to the respective bulb. This can cause the lights to appear dimmer or not come on at all.
  • Overdriving – This is when the driver is administering too much power to the respective bulb. The light produced will be brighter but will significantly shorten the life of the bulb. In addition, the more power administered the hotter the driver gets and can cause the circuit to burn out.
