1970 1980 1990 2000
5Why 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
6Why 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
7Why 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
8Why 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

13Smoke and Mirrors
- Task
- Size shape of the space
- Obstructions
- Reflectances
- Ambient temperature
- Quality, degree location of delivered
illumination
14Smoke and Mirrors
Why is fluorescent suddenly a viable option?
- MIRO 4 95 reflective aluminum
- The miraculous T5 HO lamp
15Smoke and Mirrors
- MIRO 4 Aluminum is 95 reflective
- LS Specular Anodized is 86 reflective
- but much less expensive
16Smoke and Mirrors
- MIRO 4 Aluminum is 95 reflective
- LS Specular Anodized is 86 reflective
- but much less expensive
17Smoke and Mirrors
- MIRO 4 Aluminum is 95 reflective
- LS Specular Anodized is 86 reflective
- but much less expensive
- GW PAF Gloss White Enamel is 94 reflective
18Distribution Patterns
- Widespread Distribution (gloss white)
Narrow distribution (specular MIRO4 or LS)
