Help with Light Emitting Diodes (LED) specifications:

Color
           
   Your choices are...         
   Blue       LED output is blue. 
   Green       LED output is green. 
   Infrared       LED output is infrared. Also known as an Infrared Emitting Diode (IRED), it non-thermally produces infrared light. 
   Multi-Colored       LED produces two or more colors. 
   Orange       LED output is orange. 
   Pink       LED output is pink. 
   Purple       LED output is purple. 
   Red       LED output is red. 
   Ultraviolet       LED output is ultraviolet. 
   Yellow       LED output is yellow. 
   White       LED output is white. 
   Other       Any other LED color not listed.

More Specs
   Forward Voltage:       The forward voltage the LED operates at. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Forward Current:       The forward current the LED operates at. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Luminous Intensity:       The luminous intensity of the LED in mcd. The candela (cd) is the luminous intensity of a light source producing light at a wavelength of 555.17 nm with a power of 1/683 watt per steradian, or 18.3988 milliwatts over a complete sphere centered at the light source. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Optical Power Output:       The optical power output of the LED in mW. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Viewing Angle:       Dependent upon diffusion from the lens, usually the larger the viewing angle, the less bright the LED. Diffused types generally have larger viewing angles and non-diffused types have smaller viewing angles. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Color Temperature       Color temperature is a measure of the visual "warmth" or "coolness" of the light from the white LED. The higher the value, the whiter or "cooler" the light appears. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Dual?       Two LED lamps in the same housing. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Bipolar?       Bipolar LEDs work even if voltage is reversed. Select models change color on reverse voltage. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Lens Type:       
   Your choices are...         
   Flat Lens
