BACKGROUND Currently roadway illumination for the City of Tukwila is as high as $190,000 each year in electrical utility costs. The latest advances in roadway LED lighting technology can reduce the power consumption for lighting fixtures by nearly 50 %, while providing more reliability and longer life to the fixtures. Also, the cost of LED fixtures has been going down over the years and is now only 20% higher than traditional light fixtures. This purchase will be the second phase of our LED streetlight conversion. We should expect to see lower utility costs and reduced maintenance calls as we continue to convert the older lighting fixtures that are on metered accounts throughout the City. The 2012 traffic control budget in both Streets 000.16 and 104 Fund's Annual Traffic Signal Program have remaining balances that can be utilized for this purchase. The 2011 LED purchase was bid by 2 vendors and LEOTEK Electronics was selected based on LED unit cost per fixture. Based on past performance and less inventory, we chose to stay with LEOTEK units, but purchase through a local vendor, Tacoma Electric to simplify the process. BUDGET SUMMARY 000.16.542.640.31.01 104.98.595.800.64.00 Traffic Control Supplies $ 45,072.52 Annual Traffic Signal Program 50.000.00 Total $ 95.072.52 RECOMMENDATION Approve purchase in the amount of $95,072.52 for the acquisition of 190 LED roadway lighting fixtures from Tacoma Electric and consider this item at the November 13, 2012 Committee of the Whole meeting and subsequent November 19, 2012 Regular meeting.

The pictures below tell the story of the GreenCobran". Traditional High Pressure Sodium "Cobra Head" style street lights (shown on the left) dump too much yellow Tight near the pole and spill excessive light behind the pole into neighbor's yards and windows. This is wasted light and wasted energy. At the same time, there are very dark areas in between the poles that can create very hazardous conditions. The picture on the right shows the same street illuminated with the Leotek LED GreenCobra ' units. Notice that the light is much more uniform without either the wasted light below the pole or the dark spots in between. Also, most people find the crisp "white light" produced by the LEDs to greatly improve visibility and make it easier to clearly identify colors and details. Alameda, California Before 70W HPS Drop Glass Cobra Heads System Power — 95 Watts After 40 LED Leotek GreenCobra'" System Power — 47 Watts High performance LEDs and precision optical systems: • Eliminate hazardous dark spots between poles • Substantially reduce wasteful dumps of light directly below the street light • Shield unwanted light from trespassing into residential windows • Create a highly uniform white light on the roadway enhancing night time visibility • Minimize direct uptight from the luminaire AND the reflected light from the roadway which contributes to urban sky glow 4 The Clean Daytime Form With Proven Market Performance The least controversial form will be one that matches the existing roadway luminaire as closely as possible. As the street lights are gradually changed, during the day one neighborhood won't appear different or better than another. This timeless form is ubiquitous and literally disappears from the viewer's consciousness. Unseen and unnoticed, the classic cobra head form is the simple solution for an LED retrofit. Lasting Construction Can Slash Maintenance Costs The days of sending crews out in bucket trucks to change HID street Tight lamps, ballasts, and starters are over. The GreenCobra street lights carry a 5 -year limited warranty that covers the LEDs, power supplies, finish and all other luminaire components. However, in all likelihood, these units will burn for well over a decade before any servicing is required. Long Life LEDs are projected to last a minimum of 74,000 hours (19 years) before depreciating to 70% of initial light output. Rugged power supplies are rated to last over 100,000 hours (24 years) under normal operating conditions . „Aim Fade and abrasive resistant polyester powder coat finish protects die cast aluminum housing from salt and pollutants for many years. Easy Installation and Tool -Less Electrical Maintenance Stainless steel latches allow entry to the luminaire for maintenance without tools. Large wiring chamber, full size terminal block, and quick electrical disconnects assure that installation or servicing can be done in a few minutes. In case of failure of an electrical component, the entire "power door" is easily removed and replaced. Also, in the future the luminaire can be easily upgraded for dimming and control functions. 5 LEOTEK An American Success immor- Focusing 100% on LED technology, Leotek Electronics was founded in 1992 in the heart of Silicon Valley, California. Leotek was instrumental in revolutionizing the traffic signal business and saving cities millions of dollars in energy and maintenance costs while reducing the green house gases required for powering incandescent traffic signals. Today Leotek is the leading supplier of traffic signals in North America having shipped over 4 million units in the last decade. Recognizing the benefits of LEDs over HID sources, in 2006 Leotek introduced their first LED street light. Through product innovation and superior service, today Leotek is now a leading supplier of LED street lights in the United States. In 2007, Leotek was acquired by the Lite -On Corporation. This $4 billion electronics company provides financial stability and the customer assurance that Leotek will be around for generations to honor any warranty claims and continue innovating exceptional LED products. ory Leotek Electronics USA Corp. 1 Lite -On Building 1 Milpitas, CA Broad Product Offering The Green Cobra is offered in two housing sizes for replacing up to 400W HID street lights.
