There is an new direction in Hi-Bay Lighting. . .
1970 1980 1990 2000
5
Why Fluorescent?

• Excellent lumen maintenance (LLD)
• Fluorescents lose 5-6 of lumen output at 40 of
  rated life
• Metal halide typically loses about 35
• As the lamps age, the difference becomes even
  more pronounced

6
Why Fluorescent?

• Improved color rendering
• T5 CRI is 82
• T8 CRI is 75 or 82
• MH CRI is 70 (coated) or 65 (clear), reducing
  visual acuity
• Wider choice of lamp color
• 3000K
• 3500K
• 4100K
• 5000K
• Negligible color shift
• Unlike metal halide, fluorescent lamps maintain
  consistent color throughout their life

7
Why Fluorescent?

• Instant restrike
• Fluorescent lamps are back on instantly
• HID sources can take several minutes
• Safety/security risk
• Lost sales
• Versatile control options
• Generators
• Battery packs
• Photocells
• Dimming
• Sensor friendly
• New Developments in T5 Technology
• 3-Lamp and 4-Lamp 54W ballast available now
• 480V 347V 1-Lamp and 2-Lamp ballast available
  now

8
Why HID?

• Ambient temperature tolerance
• Consistent light output above 120F (50C) and
  below 50F (10C)
• Lower Installed Cost
• Customers who don't care about maintained costs
• Massive lumen packages
• Extremely high mounting heights suggest 1000W MH
• Severe environments requiring specialized
  fixtures
• Corrosive or exceptionally dirty
• Subject to vibration or violent impact
• Hazardous locations

Smoke and Mirrors

• Task
• Size shape of the space
• Obstructions
• Reflectances
• Ambient temperature
• Quality, degree location of delivered
  illumination

Why is fluorescent suddenly a viable option?

• MIRO 4 95 reflective aluminum
• The miraculous T5 HO lamp

15
Smoke and Mirrors

• MIRO 4 Aluminum is 95 reflective
• LS Specular Anodized is 86 reflective
• but much less expensive
