INTRODUCTION Trident Seafoods Dreyers Ice cream Dominos Distribution Crown Distributing Maletis Beverage Tiger Mountain Beverage Unisea (Mrs. Fridays Fish) Boeing Company Paccar Corp. Office Depot Dist. A Few of Our Clients Include: Pacific Energy Solutions and our partnered manufacturer have teamed up to produce a proprietary line of fixtures, to meet the special needs of the food and cold storage industry. This partnership brings an innovative approach to Low maintenance and energy efficient lighting for your entire facility.
Warehouses & Dry Goods Replaced 400-watt Metal Halides with 234-watt T5 = 50% Energy Reduction
Refrigerated Areas BeforeAfter 234-watt Arcticlite T5 With MOTION SENSORS 60% plus Energy Savings 400-watt Metal Halide
Freezers to –20 F Before 400-watt High Pressure Sodium After 234-watt Arcticlite T5 with MOTION SENSORS 65% Energy Savings
Old Technology High Pressure Sodium Mercury Vapor Metal Halide T-12 High Output and VHO
HID Light fixtures Very low visibility. Poor color rendering (CRI) Lower lumens per watt. Human eye is less perceptive to these lumens. Depth perception is affected. Re-strike time of minutes. High operating temperatures.
HID continued Lumens drop off very quickly. As high as 60% Depreciation at end of life. Non-Passive failure is a safety concern. Colors change (shift) over time.
T-12 HO and VHO Older technology. Harder to design a fixture to provide directional light. Lumen depreciation is a problem. More watts than are necessary. Repeated on-off cycles shortens lamp life. Magnetic ballast being discontinued.
T-5 Solution Better Light Distribution. Longer lamp life ( 35,000 hours). Instant Re-strike. Controllable with motion sensors. T-5 has better maintained lumens. Typically 50%+ in energy savings.
Why T-5s Work T-5 lamps have a 5/8 cross section. This makes it possible to use parabolic reflectors for better optics to put the light to work. Higher CRI of 85 increases the perceived visual brightness. Scotopically and Photopically superior light source. Are not a point source – glare is reduced. There are less shadows because of the number of lamps contributing light to each point.
CRI Ratings Lamp TypeCRI Sun Light100 T-585 Standard MH60-70 Pulse MH65-70 HPS22 LPS5 Fluorescent and HID lamps Measured on a scale of 0 to 100, the color-rendering index (CRI) describes the capability of a light source to accurately render a sample of eight standard colors relative to a standard source. Light sources that exhibit higher CRI's render color better than sources with low CRI's.
Why Measured Lumens Mislead. Light meters are calibrated to detect raw lumens. The human eye cannot use many of these lumens. High CRI and scotopic light sources are easier on the eye and reduce the strain of accommodation or holding the eye focused. It has been shown that the eye doesnt react to just raw lumens alone, but to the spectrum of light interacting with the cones in the retina. Even with less lumens, enhanced light is perceived as brighter by the human eye.
Lamp Lumen Maintenance T5 Fluorescent = minimal depreciation Rated Lamp Life = 35,000 hours T-5S MAINTAIN 93% OF LUMENS HID's have significant lumen depreciation, which will require premature lamp replacement to maintain original light levels. For a Standard Metal Halide (12,000 – 20,000 hrs. rated life) 80% OF INTIAL LUMENS AT 40% OF RATED LAMP LIFE AND 40% - 60% OF INITIAL LUMENS AT END OF LAMP LIFE
Lamp Life Comparison
CONTROLS HID AND MAGNETIC BALLASTS Very limited because of warm-up and re-strike times. For example: HID hi-bays in most facilities are left on all day even in un-occupied areas as they take too long to turn on. High/Low controls systems can save some energy, however it is not linear between wattage and light output. 50% OF LIGHT LEVELS CONSUMES ABOUT 65% OF MAX WATTAGE
CONTROLS – T5 Fluorescent Because of instant ON motion sensors can be used to reduce burn times in often vacant areas. In warehouses, burn times can potentially be reduced 30%- 60% reducing maintenance cost. Motion sensors are used on each individual fixture providing light only in occupied areas. Daylight sensors (photocells) can be used where daylight from skylights or windows are present. T-5 program start ballast allow up-to 50,000 starts.
Crown Distributing Arlington, WA
Crown Distributing Arlington WA Existing fixtures consisted of 400-watt Metal Halide Hibays. Rack aisles, Keg storage, Loading docks. and Maintenance area. Replaced with Arcticlite (4-lamp) Vapor-tight F54T5HOs, wattage was reduced from 460-watts per fixture to 234-watts. per fixture. Motion sensors were used on each fixture and set for a ten minute on time Total energy reduced by over 60%.

Additional Savings Due to Reduced Cooling load HID type fixtures operate at very high temperatures. Typical bulb wall temps can reach degrees Fahrenheit. T5 lamps operate at degrees. Lower operating temperature means less heat introduced into your coolers. This can account for an additional 12-19% savings beyond the reduced lighting load.
