What is the Difference between Lumens and Watts?

Watts is how much energy a light bulb uses, but Lumens is how bright it is. Lower wattage products like LEDs and CFLs save energy by using less wattage to operate, but their brightness, or lumens, is equivalent to the traditional incandescent light bulbs that they replace. For example, a 6W LED replaces a 40W incandescent light bulb but saves 34 watts in energy.

What is Color Temperature?

Simply put, color temperature is how the light appears. The lower the color temperature, the warmer the light makes a room appear (2700K), the higher the color temperature, the cooler the light will appear (5000K and up).


Lighting Shapes
  • A Shape - General Use

  • B Shape - Decorative or Decor Use

  • G Shape - Globe

  • R Shape - Reflector, typically small indoor directional lighting

  • BR Shape - "Bulge" Reflector, this is indoor directional lighting

How to Understand a Lighting Facts Label
  • The lighting facts label which appears on every lighting package, provides brightness (lumens) rating

    and the energy savings estimate

  • Life in years, based on the average use of 3 hours per day, 365 days a year

  • Light appearance is the color temperature of the light

  • Energy usage = wattage​
