9. What is CRI? Color Rendering Index
A numeric indication of a lamp’s ability to render individual colors accurately relative to a standard
CRI value is derived from a comparison of the lamp’s spectral distribution to the standard at the same color temperature

18. Benefits and Features Overview

19. Photopic lumens (day time)
• Published lumen ratings
• Light measurement based on daytime observations
Scotopic lumens (nighttime)
• Lumen measurements corrected for nighttime vision
S/P Ratio
• The ratio of light measured by the photopic and scotopic methods

20. S/P Ratio Comparisons for Outdoor Lighting
• The S/P Ratio of 5000K daylight light sources is 2.1
• The S/P Ratio of 4000K light sources is 1.65
• The S/P Ratio of 3000K light sources is 1.4
• The S/P Ratio for yellow HPS light sources is 0.64

21. What Does the S/P Ratio Tell Us about Outdoor Lighting?
• Lamps with high S/P ratios (high scotopic content) improve one’s ability to see outdoors.
• A 4000K light source is at least twice as effective for viewing at night as HPS sources. Similarly, a 5000K light source is more than 3 times as effective as HPS sources.

22. What Does the S/P Ratio Tell Us about Indoor Lighting?
• Lamps with high S/P ratios (high scotopic content) improve one’s ability to see indoors.
• Human studies have shown that the S/P values, though previously applicable to only nighttime conditions, can be used to describe the "effective lumens" of indoor lighting as well.
• Example: If two rooms are lit separately with 4000K and 5000K lamps to equal photopic luminance, the 5000K room will appear at least 13% brighter.

23. What are “Effective Lumens”?
• As defined by Dr. Ian Lewin, the term “effective lumens” describes the modified lumen output of a lamp, taking into account the shifting color sensitivity of the eye at low light levels.
• The Effective Lumen rating reflects the lumen rating of Natural White lamps is given relative to 4000K lamps. The formula used to determine this rating indoors is (S/P)0.5. This provides the end user, lighting designer or contractor with an accurate comparison of traditional 4000K lamps to 5000K lamps.

24. How does this relate to Natural White?
With a high S/P ratio of 2.1, Natural White lamps provide customers with an:
• Improved ability to see indoors
• Improved nighttime vision
This makes Natural White an excellent product for either indoor or outdoor lighting applications. Combined with high CRI and high CCT, the Natural White lamp/ballast system features superior color rendering, as well as all the benefits of Uni-Form arc tube and Opti-Wave ballast technology.
