This long history has trained the average homeowner to think of lighting an area in terms of whether it needs a 40, 60, or Watt bulb.
Even today, manufacturers of CFLs and LED light bulbs tend to stress the incandescent equivalent wattage rather than the actual, much lower wattage of the bulb. Lumens and Candlepower: As the lighting industry shifts away from incandescent lighting, it will become more and more important to focus on the actual light output of a bulb rather than how it compares to an incandescent light bulb.
Lumens, also shown as lm, represent the actual amount of ambient light coming from a lamp. Candlepower, on the other hand measured in candelas , is a unit of measurement that stands for the luminous intensity going in a specific direction from a light source.
Lighting sources at the low end of the index, such as low-pressure sodium lamps CRI tend to wash out colors and are best used in commercial applications where accurate color rendering is not important. Linear fluorescents and compact fluorescents CFLs usually fall in the 80 to 90 range.
While CRI represents how accurate a light source is, color temperature represented in degrees Kelvin K represents the character of the light source.
