T8 -vs- LED TWO PROJECTS, TWO WINNERS: Why LED Isn’t Always the Only Option in Modern Lighting Efficiency Projects Presented by The Retrofit Companies // Wendy Fry and Chris Wendling Two Projects, Two Winners ? 2 Facilities, Alliant customers, rebate eligible. ? Both presented with T8 LED options. ? Each chose a different energy-efficient solution. o Quaker Oats Railway Load Out Area ? Phase 2 of project started in 2010 o Oelwein Public Library ? Retrofitting from existing T5 system T8 -vs- LED How Quaker Chose a Winner Project Back Story ? 2010: TRC completed T8 fluorescent lighting project in a majority of plant production areas. ? Fixtures installed were wash down vapor tight fixtures. + Vapor Tight construction keeps dust out of fixtures. + Food production facilities require shatter-shield lamps in all areas. ? Load out areas were not upgraded during 2010 project. ? Existing lighting: metal halide, high pressure sodium, T 12. ? The light levels quality were relatively poor in comparison to other areas of the plant. T8 versus LED Comparison ? The proposed fixture options were available in either T8 or LED. ? The savings of the LED over T8 was approximately 30% more. ? Rated life of LED is approximately 30% longer than T8. ? Quaker was ready to try LED for the 2014 project. T8 versus LED Comparison ? Existing Lighting Costs: $5,475 ? T8 Annual Savings: $2,517.10 ? LED Annual Savings: $3,740.96 ? Rated life for T8: 36,000 hours / Delivered lumens per watt 66 o 12 hour start, Philips instant start ballasts, 32w high lumen lamps. F32T8/TL850 ALSO Plus/TG ? Rated life for LED: 51,000+ hours / Delivered lumens per watt 101 o L70. 90,000 hours via TM-21 Wha
