  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

  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 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

  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?

  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 Source: Ecova

  9. Utility Perspective:Cost per kWh for LED bulbs post standards Example— LED PAR38 Source: EPA, Next Generation Lighting Programs. Reformatted by IEE.

  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 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.  

  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
