  Spectrum Characteristics  
  LiteBlue LED emits high blue light content (415 - 490 nm) with exceptionally high ratio of blue-turquoise light (456 - 490 nm) at 0.9 : 0.1 roughly as compared with blue-violet light (415 - 455 nm), and their mix percentages of different color temperatures are listed below,

 
 
Part number Color Temperature Blue Light Content 1 Blue-Violet 2 Blue-Turquoise 3 Ratio 4
LB2835-50-465 5000K CCT 27% 14% 86% 0.1 : 0.9
LB2835-40-465 4000K CCT 21% 13% 87% 0.1 : 0.9
LB2835-30-465 3000K CCT 13% 8% 92% 0.1 : 0.9
 
 
 
Note: 1. Blue Light Content is the percentage of blue light out of total spectral power of visible light spectrum
2. Percentage of Blue-violet light within the Blue Light Content
3. Percentage of Blue-turquoise light within the Blue Light Content
4. Mixture ratio of Blue-violet light and Blue-turquoise light within the Blue Light Content
 
 
 
  Higher dosage of blue-turquoise light is always preferred to blue-violet light for indoor lighting during daytime, because of the following two advantages,

 
 
1. Higher EML (Equivalent Melanopic Lux) to improve the efficiency of regulating the Circadian Rhythm.
2. Lower LB (Retinal Blue Light Radiance) of Blue Light Hazard can be achieved, which is illustrated in the European standard IEC/EN 62471 (Photobiological safety of lamps and lamp systems).
