Let’s not put LED on a pedestal Keep it light

A Midsummer’s Light Dream Plus the top 5 mistakes to avoid when evaluating LED Lighting History How it Works Advantages / Disadvantages Lighting Projects Energy Projects Pairing with Renewables Not evaluating LED Over-lighting & Under-lighting Waiting (the Cost of Waiting)

History of LED

Mistake #1 – Not evaluating LED By the end of this presentation, I hope you’ll all be convinced you are a candidate for LED and ready to get an assessment. It’s too expensive We can’t afford it It wouldn’t be worth it Special applications

History of LED Luminescence of carborundum crystal discovered in 1907 Scientist at General Electric made the first useable LED in the visible spectrum in 1962 Prices of LEDs came down in the 1970s - Early uses were in Screen displays, TV remotes, calculators and watches Early 2010’s – LED starts to gain commercial / residential viability as an expensive but efficient competitor to fluorescent

How it Works Direct current Luminescence

How it works Like a solar panel in reverse. A P-N junction can convert absorbed light energy into a proportional electric current. The same process is reversed here (i.e. the P-N junction emits light when electrical energy is applied to it).

How it Works - Drivers LEDs are designed to run on low voltage (12-24V), direct current electricity. However, most places supply higher voltage (120-277V), alternating current electricity. An LED driver’s main purpose is to rectify higher voltage, alternating current to low voltage, direct current.

Advantages of LED Lower energy consumption Longer lifetime Improved physical robustness Smaller size Faster switching

Disadvantages of LED Sensitivity to heat Maintenance factors Fit into existing fixtures / applications Easy to overlight

Mistake #2 – Over- & Under-Lighting By the end of this presentation, I hope you’ll all be convinced you are a candidate for LED and ready to get an assessment. The more light the better Same fixture throughout the building Glare and Shielding

Mistake #3 – Not considering other savings or value from LED Cows produce more milk, Increased productivity Safety Maintenance Industry Specific

Rebates

Bureaucracy in Lighting Fraud, watered down standards, knock-offs https://www.designlights.org/news-events/news/notice-regarding-lm-80-data-obtained-from-citizen-electronics-laboratory/

Mistake #4 – Not evaluating controls Cows produce more milk, Conservation vs Efficiency Maximize rebates Maximize savings

The Price is Light

Energy Savings Examples Customer Industry Price Rebates Savings (energy & maintenance) Payback (years) Grocery Store $ 45,691.46 $ 18,661 $ 27,406 0.98 Health Center $ 40,677.58 $ 14,678 $ 20,598 1.26 Manufacturing $ 205,066.7 $ 79,051 $ 69,148 1.82 Car Dealership $ 95,350.37 $ 11,475 $ 28,151 2.97 Religious Facility $ 24,957.27 $ 552 $ 1,624 15.02 Nursing Home $ 74,693.98 $ 3,023 $ 40,487 1.77

Mistake #5 – Waiting The Cost of Waiting Prices at an all time low Kirtz would have been paid off if he would have acted all those years ago / Get the cards out now! The Cost of Waiting Prices at an all time low Financing readily available

THE COST OF WAITING 5 Story Office Building Project Cost $74,100 Average Monthly Savings $481 Simple Payback 3.08 years Delay 1 year ? Penalty / year $20,374 Finance Terms 5 years / 7% Total Interest over 5 years $13,936 Net Positive +++++++ $6,438 more cash (by financing, rather than waiting 1 year)
