Color rendering index (Ra):                                                                                


Coloring Rendering Index (Ra) - CRI represents the quality of light and its faithfulness to render colors correctly, that is, to enable us to perceive colors as we know them. The ideal CRI is 100, and some incandescent bulbs approach this level. LEDs and CFLs use different design components in trying to equal the CRI of incandescent bulbs. LED bulbs CRI ratings range from 70 to 95, and the best CFLs have ratings in the mid 80s. The LED CREE CR6 bulb, for example, features a CRI of 90 Warm White making it one of the highest in the industry.

Lumen                                                                                              


Lumen - a unit of standard measurement that is used to describe the amount of light contained in an area as perceived by the human eye. The more lumens, the brighter the light. You can use lumens to compare the brightness of any bulb, regardless of the technology behind it, and regardless of whether it's incandescent, CFL or LED. 


Estimate desired brightness - read the package to choose desired brightness level. You can use wattage to compare bulb illumination, for example, a 9W LED is equivalent in output to a 45 W incandescent. However, the new method for comparing bulbs is lumens. Lumens is the measuse of perceived brightness, and the higher the lumens, the brighter the bulb. The FTC has mandated that all light bulb packages display lumens as the primary measure for comparing bulbs. 


Choose between warm and cool light - new LED bulbs are available in 'cool' white light, which is ideal for task lighting, and 'warm' light commonly used for accent or small area lighting.


Standard base or pin base - LEDs are available in several types of 'pin' sockets or the standard "screw' (Edison) bases for recessed or track lighting.




? Choose between standard and dimmable bulbs - some LED bulbs, such as the Switch, LEDnovation and FEIT LED bulbs, are now available as dimmable bulbs. They will work on your standard dimmer switch.
Look for certifications - including CE,RoHS FCC, Energy Star and UL
