2 Nominal CCT of 5000K90+ CRI The Ultimate White Light

3 Bring Daylight Indoors! Benefits

4 High CRI 90+ High CCT 5000K Full Spectrum The Color of Natural Sunlight! Features

5 Objects appear as they would outdoors Blues are true blue Whites are whiter Reds are more vibrant Benefits

6 Full Spectrum Spectral emission in all parts of the visible spectrum and in the near UV CCT of 5000K CRI of 90+ Natural White lamps are a full spectrum product!

7 Natural White Daylight at 5000K Light output in all parts of visual spectrum

8 Color Temperature NameCCT RangeDescription 27K KVery Warm...incandescent color (2750K)…only available in a coated version 3K KWarm…close to halogen lamp color (clear 3200K, coated-3000K) 4K KNeutral…close to fluorescent or mercury cool white(clear-4000K, coated-3700K) 5K5000KDaylight…close to color of the sun. Often called a full spectrum source 6K6500KDaylight…close to average outdoor sky color 10K10,000KBlue-White…close to clear blue sky color….for aquarium lighting High CCT

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

10 Uni-Form pulse start technology - Uni-Form arc tube - Weldless mount - UV Shield shroud Opti-Wave ballast technology Features

11 Workspaces and areas look brighter Tasks, such as reading, become easier to perform More lamps operating to rated life Increased lumen maintenance

12 More consistent color from lamp to lamp A regular benefit of 20,000

13 Twice as fast as ceramic metal halide Don't be left in the dark! A regular benefit of

14 Lasts longer than standard metal halide or ceramic metal halide Fewer failures 70% survival at end of rated life Rated life hours A regular benefit of

15 Weldless Construction A regular benefit of Elimination of #1 cause of Failure Mode Most Durable HID Lamp Available - Shipping - Vibration More Consistent LCL

16 ANSI type-O rating Complies with 2005 NEC Operate continuously without weekly shut-downs Protect merchandise and signage from fading Blocks nearly all the damaging ultraviolet light A regular benefit of

17 Improved lamp lumen maintenance (90%) Improved ballast efficiency Lower audible ballast noise One Call Warranty A regular benefit of

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 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 S/P Ratio Comparisons for Outdoor Lighting

21 Lamps with high S/P ratios (high scotopic content) improve ones 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. What Does the S/P Ratio Tell Us about Outdoor Lighting?

22 Lamps with high S/P ratios (high scotopic content) improve ones 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. What Does the S/P Ratio Tell Us about Indoor Lighting?

23 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. What are Effective Lumens?

24 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. How does this relate to Natural White?
