1. Summary of IEE LED Reflector Lamp Recommendations Project Adam Cooper NARUC Winter Meeting, Washington, DC February 5th, 2012

2. IEE lighting project  New lighting standards have an impact on both consumers and on utility lighting programs  LED is a promising technology aptly suited for directional lighting applications  IEE project goals: –Identify and recommend efficient LED reflector bulbs that also provide an aesthetically pleasing, consumer friendly experience –ID the “consumer friendliest” of the ENERGY STAR LEDs  Why? –Want consumers to choose an efficient bulb and be happy with it  IEE worked with Ecova to test bulbs and TopTen USA to display results 2

3. What is a reflector bulb?  A reflector bulb is cone-shaped and produces a directional beam of light.  Typically used in recessed can, track, and outdoor lighting fixtures  Used for spot and flood lighting  We focused on PAR20, PAR30, and PAR38 bulbs 3 Examples of common uses Source: Images courtesy of EPA and Ecova

4. Lighting is an art as well as a science  Evaluation consisted of two phases –Selecting the most promising lamps to purchase for testing Note—All lamps are ENERGY STAR ENERGY STAR has done a lot of the hard work –Selecting the best in class performers Used scoring criteria broken into 4 categories—energy, economics, measured and qualitative light performance Key here is lab data + human evaluation 4

7. Findings and observations  High efficacy LED products can deliver satisfying light to consumers  The results demonstrated that the overall observed quality of LED PAR lamps tested typically equaled, or exceeded, the perceived light qualities of halogen incandescent bulbs  All LED reflector lamps will save energy, before and after the reflector lamp standards take effect, so which ones will people like the best? 7

8. Consumer Perspective: Price points matter, incentives help  Average cost of top ten recommended LEDs is $40 compared to halogen incandescent bulb at $6.50 –Note: Average cost of all tested bulbs was $60  #1 Recommended bulb –Manufacturer: TCP –Lifetime cost savings: $200 –Payback period: 4 years –Lifetime kWh savings: 1,800 –Cost of bulb $54 8 Source: Ecova

10. Utility lighting program  Utilities use upstream lighting programs to buy down cost. –Utility programs offering rebates for LED products not as numerous as CFLs, but changing –28% of ratepayer-funded residential EE programs include LED products; 87% offer CFL products –Utility LED rebates typically capped at $5. Some utilities pursuing rebate cap of $15 per bulb  Opportunity to strategically expand list of LED rebates –TopTen recommendations can be used to identify products for premium rebate –Utilities can use IEE study results on own website 10 Source: CEE, Annual Industry Report 2011 (forthcoming)

11. TopTen USA and utility program collaboration  TopTen USA ranks the top ten most efficient products in 10 product categories. Now including lighting. –But lighting is not just about efficiency  Utilities have used TopTen to –Promote customized version of TopTen to consumers as an easy tool to identify the best of the best –Encourage retailers to stock and promote TopTen products  Premium utility incentives – Add TopTen to existing incentives for special promotion, added incentive/discount/gift with purchase –Example: NEEA provided higher mid-stream rebates to TopTen qualifying televisions. 11

12. Recommended next steps  Determine LED appropriate rebates –Can’t use the same rebate amount on CFLs as LEDs; Need to increase rebate amount  For utilities that don’t have experience with LED rebates –Rebate lamps using TopTen recommendations since lamps are tested and screened for efficiency and customer acceptance  For utilities that already rebate ENERGY STAR LEDs – Offer premium incentives for TopTen bulbs  Several utilities interested in using recommendations list and expanding lighting categories this year 12
