1. E. W. Dovel Lighting: Facts and Fiction

2. INNOVATIVE EFFICIENT SOLUTIONS™www.HarrisLighting.com904 284-1220 The most important citizens in the USA are our men and women serving currently and the Vets that went before them! Our Starting Point

3. INNOVATIVE EFFICIENT SOLUTIONS™www.HarrisLighting.com904 284-1220 Fact Checker calls this “Mostly True”

4. INNOVATIVE EFFICIENT SOLUTIONS™www.HarrisLighting.com904 284-1220 Outline LED lighting, the greatest thing in lighting since electricity? What is the “best” lighting. What’s the difference Can’t I get everything I need to know from marketing info or the media?

5. INNOVATIVE EFFICIENT SOLUTIONS™www.HarrisLighting.com904 284-1220 The best measure for a lighting system? Approximately 50% of the equation for light levels is the lumens/watt. Approximately 50% is the environment those lumens sit in. What are the some other factors? –Cost –Lamp life –CRI/K temp –Heat

6. INNOVATIVE EFFICIENT SOLUTIONS™www.HarrisLighting.com904 284-1220 Greatest Thing since Thomas Edison? YES, NO, MAYBE?OR NOT!

7. INNOVATIVE EFFICIENT SOLUTIONS™www.HarrisLighting.com904 284-1220 Let’s go to the Video!

8. INNOVATIVE EFFICIENT SOLUTIONS™www.HarrisLighting.com904 284-1220 Now a REAL Alternative!

9. INNOVATIVE EFFICIENT SOLUTIONS™www.HarrisLighting.com904 284-1220 Haitz’s Law Every 10 years, the cost per lumen (unit of useful light emitted) falls by a factor of 10, and the amount of light generated per LED package increases by a factor of 20, for a given wavelength (color) of light. Similar to Moore's law, which states that the number of transistors in a given integrated circuit doubles every 18 to 24 month, i.e. computers.

10. INNOVATIVE EFFICIENT SOLUTIONS™www.HarrisLighting.com904 284-1220 T12s – You are not alone! Obsolete July 14, 2012 19.8% of fluorescent lamps sold in 2013 were T12! –Posted 4/24/2013, LightNow. And you want to put LED in the troffers? Many rebate programs have eliminated any rebates for T12 already.

11. INNOVATIVE EFFICIENT SOLUTIONS™www.HarrisLighting.com904 284-1220 “What’s the Difference?” As K temp goes above 4100 in fluorescent, lm/w go down, with LED it goes up! Quantity matters with LED, not traditional light sources Timing is critical, LED is 8 weeks, HID, 3 days. Advances are out pacing attempts at policy by 18 months!

12. INNOVATIVE EFFICIENT SOLUTIONS™www.HarrisLighting.com904 284-1220 Best Solution Less energy used, lowest cost and sustainable! Interior – T8!!! Outdoor – Induction, LED, Metal Halide? Easiest energy policy in the world! Use what we already have and fix what we already own!

13. INNOVATIVE EFFICIENT SOLUTIONS™www.HarrisLighting.com904 284-1220 Real World, Indoor Indoor 4 lamp, T12. Must hit 50FC and save energy. 4 lamp retrofit with LED tubes or 2 lamp, T8? –$80 versus $200 –42K hrs. versus 50K? –51 watts versus 50 –94 lumens versus 90

14. INNOVATIVE EFFICIENT SOLUTIONS™www.HarrisLighting.com904 284-1220 Real World, HID – REALLY? BEFOREAFTER

15. INNOVATIVE EFFICIENT SOLUTIONS™www.HarrisLighting.com904 284-1220 Real World, Outdoor 1000watt HPS to 320 watt MH. –Scotopically it works! Blount Island Marine Command LED, Take a look at this photo!

20. INNOVATIVE EFFICIENT SOLUTIONS™www.HarrisLighting.com904 284-1220 Or this one “LED does not attach bugs” LED has no special provisions to limit bugs attraction. Bugs are attached to light for the same reason humans are, they can see better. The BUG system actually is a Dark Sky component to provide a system for light escaping, “B” is backlight, U is uplight, G is glare.
