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

Available optical distributions available. (DSX Area LED) 6

LED Area Lighting Optical Distributions are Key to: Key* - High Performance Reduce hot spots and spread - Reduced Costs (wattage/fixture & # of fixtures) as evenly as possible. It all comes down to average foot Tailor fit the design for reduced Costs, Energy and candles. Carbon Footprint! 7

R ECENT T RENDS : LED L IGHTING INTERIOR S OLUTIONS  Cost-Effectiveness Barrier  Numerous retrofit solution strategies  Linear Lamp Retrofit Solutions  Utilizes fluorescent performance characteristics  Internal ballasted LED tube  requires disconnect of existing fluorescent ballast  External ballasted LED tube  requires disconnect of existing fluorescent ballast and install of new driver/ballast for LED tubes  “ Plug-n-Play ” LED tube simply uses the existing fluorescent ballast  Utilizes LED performance strengths  Retrofit Panel Units

R ECENT T RENDS : LED L IGHTING INTERIOR S OLUTIONS  Screw & Pin Base Lamp Replacements  Very Cost-Effective  Heavily incentivized by Utility Co.’s  Be Cautious  Enlarged bases due to heat sink  Install samples to ensure compatibility  Voltage availability  Dimming compatibility

U TILIZING LED S TRENGTHS  Dimming Drivers are standard  Design with an eye to:  daylight harvesting  Motion capture coupled w/ dimming  Utilize dimming range vs. on/off controls in areas w/ safety concerns  Exterior occupancy controls  Granular control & response
