Hudnut Company LED Lighting presentation, Part 2 (Aaron Leatherwood)

  1. 1. And now… …TheNitty Grittywith your hostAaron Leatherwood<br />
  2. 2. Lighting is one component of a whole energy efficiency package, <br />but one that can affect many of the other components.<br /><ul><li>Lighting energy usage
  3. 3. Air leaks
  4. 4. Added cooling costs
  5. 5. Load on alternative energy sources</li></li></ul><li>There are many applications where LED lamps are appropriate<br /><ul><li>Projects with challenging maintenance areas
  6. 6. Projects with 24/7 operation</li></li></ul><li><ul><li>High security projects
  7. 7. Projects with mechanical vibration issues</li></li></ul><li>Projects with high electrical rates<br />
  8. 8. LED technology is progressing quickly<br /><ul><li>Linear LED lamps tested by the DOE in June of 2009 had a maximum lamp efficiency of 70 lm/W
  9. 9. Most quality linear LED lamps now produce 80+ lm/W
  10. 10. CRI in 2009 was in the 70s for most LED products
  11. 11. Quality LED lamps now are mostly 80+ CRI
  12. 12. Many LED products now dimmable on standard dimming systems</li></li></ul><li>CRI not the last word in color rendering <br /><ul><li>The DOEnow recommends using CRI as a general guide, but leaving final test to your eyes.</li></li></ul><li>Thermal Management<br />Heat dissipation ability of the chip SMD versus “through hole”<br />SMD (Surface Mount Diode)<br />Through hole – AKA - 5mm <br />
  13. 13. Fins, Metals, and Unicorns… <br />Oh my…<br />
  14. 14. Fins <br />More is not necessarily better…<br />
  15. 15. Metals<br />
  16. 16. Unicorns don’t exist… yet…<br />50 watt MR16 LED equivalent (12 watt LED MR16)<br />Peanut lamp LED replacement<br />1000 watt HID equivalent LED sports lighter<br />50,000 hour, super bright, good color, 5 year warranty and all for $9.99<br />
  17. 17. LED Life<br />The first LED products claimed lives of 100,000+<br />This was to 50% of original light output, not 50% failure<br />IESNA and DOE state that the technical end of life is at 70% of original output<br />Typically 50,000 hrs on quality products 5.7 years 24/7<br />Slow dim out over time – not instant failure<br />
  18. 18. <ul><li>LED life is not affected by frequent switch cycles (motion sensors, daylight sensors, etc…)
  19. 19. LEDs love the cold and are typically rated to run in negative 40F through +120F ambient</li></li></ul><li>How does fluorescent compare?<br />Fluorescent now typically rated for 30,000+ with 96% lumen maintenance <br />30,000 average in test conditions to 50% failure rate<br />1 switch cycle per day required<br />DOE recommends that lamps are group relamped at 70% or 21,000 hours<br />End of life means dead out with fluorescent<br />Still problems with many fluorescent dimming systems<br />
  20. 20. How to find a good LED product<br />Find a manufacturer that answers questions and backs answers up with data and a good warranty<br />Get an evaluation sample to make sure it meets your requirements in the application<br />Mock-up is the best way<br />Watch out for LED discounters selling old technology online<br />Purchase through your favorite distributor, showroom, or ESCO. <br />
