  1. Warehouse and Industrial “Big Box” Retail There is an new direction in Hi-Bay Lighting. . . 1970 1980 1990 2000

  2. 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

  3. 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 • 3000°K • 3500°K • 4100°K • 5000°K • Negligible color shift • Unlike metal halide, fluorescent lamps maintain consistent color throughout their life

  4. 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

  5. Why HID? • Ambient temperature tolerance • Consistent light output above 120°F (50°C) and below 50°F (10°C) • 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

  6. LHB • Linear Hi-Bay with Brio™ optics • Up to 93% efficient • Three louver options • Miro4™ High-Efficiency • LS Specular Anodized • MA Matte Anodized • 4’ replaces 175-250W MH • 8’ replaces 250-400W MH • T5HO • 2-lamp cross section

  7. LHE • Economical T5 Hi-Bay • Up to 98.6% Efficient • Two body widths • 10” LHEM for 2 or 4 T5 lamps, 2 T8 lamps • 15” LHEW for 4 or 6 T5 or T8 lamps • Two lengths • 4’ • 8’ (narrow body with tandem lamps—8 lamps total) • Multiple shielding options • Cross baffle • Wire guard • Cage guard • Lens

  8. LHR Wide Body • Linear Hi-Bay with Chambered Reflector • Up to 99% efficient! • Three reflector finishes • Miro4™ High-Efficiency • LS Specular Anodized • Gloss White • Replaces 175-400W MH • 4-lamp or 6-lamp T5HO or 6-lamp T8 • Optional 6% or 12% uplight

  9. LHG Recessed • LHR adapted to grid ceilings • 2x4 6-lamp T5 or T8 • Three reflector finishes • Miro4™ High-Efficiency • LS Specular Anodized • Gloss White • Optional shielding • Door & lens • 11GA wireguard

  10. BALLAST FIXTURE LAMP ENVIRONMENT Smoke and Mirrors • Task • Size & shape of the space • Obstructions • Reflectances • Ambient temperature • Quality, degree & location of delivered illumination

  11. Smoke and Mirrors Why is fluorescent suddenly a viable option? • MIRO 4™ 95% reflective aluminum • The miraculous T5 HO lamp

  12. Smoke and Mirrors • MIRO 4 Aluminum is 95% reflective • LS Specular Anodized is 86% reflective • …but much less expensive

  13. Smoke and Mirrors • MIRO 4 Aluminum is 95% reflective • LS Specular Anodized is 86% reflective • …but much less expensive

  14. Smoke 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

  15. Distribution Patterns Narrow distribution (specular: MIRO4 or LS) Widespread Distribution (gloss white)

  16. Smoke and Mirrors And how about those T5 HO lamps…

  17. Smoke and Mirrors Energy Consumption 22% Lower Watts 48% Lower Watts 52% Lower Watts

  18. Smoke and Mirrors Delivered, maintained lumens per watt (light/$)

  19. LHR Narrow Body • Up to 89% efficient • Three reflector finishes • Miro4™ High-Efficiency • LS Specular Anodized • Gloss White • Replaces 175-400W MH • 4-foot or 8-foot • 2-lamp or 3-lamp T5HO or T8 • Optional uplight
