W HY LOOK AT L IGHTING R ETROFITS ? Improved Environmental Comfort: Lighting retrofits provide improved lighting for workplace staff “Proper light levels improved the concentration and test scores of the students” - Wesselowski, Schulte-Markwart, 2010 Best Payback/Savings: Lighting typically provides the best return on investment/payback Interior Lighting Retrofits (Non-LED): 3-6 year payback Exterior Lighting Retrofits (LED): 5-9 year payback LED Solutions Represent the 3rd Wave of Lighting Retrofits T12 to T8 32W T8 32W to Low Watt T8 (28W/25W), LBF Ballasts
I DENTIFYING O PPORTUNITIES (4)+ years since construction or last lighting upgrade – Presence of T-12 or T-8 32 watt lamps (typical design of newer buildings) – Re-lamp /Re-ballast (Utilizing 25 or 28 watt lamps / LBF ballasts) – De-lamp fixtures (retrofits) 4-lamps to 2-lamps / 3-lamps to 2-lamps / 4-lamps to 3-lamps HID Lighting – Gymnasiums, Shop Areas, Labs, Can Fixtures, etc. Typical design of newer buildings – Parking Lots, Wall Packs, Exterior Canopy and Walkways, etc. Typical design of newer buildings Absence of Occupancy Sensors or Presence of Incandescent EXIT Signs
R ECENT T RENDS : LED L IGHTING Quality More Energy Improvements Efficient Market Leaders – Cree, Improved Efficacy (i.e. Lithonia, Sylvania, GE more light with less energy) Chips/Drivers – Cree, Nichea, LG, Sylvania, Samsung 455 watt parking lot head = Improved light output and 131 watt LED 270 watt parking lot head = “spread” – especially 45 watt LED exterior Ex. Lithonia D-Series Increased Life Expectancy 92-119LPW depending on (70,000 – 100,000 hours) drive current, Kelvin, & Compared to 20,000 hours Distribution for metal halide
