• Use light emitting diodes (LEDs) to generate light. • What are LEDs? – LEDs are semiconductor diodes that generate light when current flow from positive to negative junction. + ‐ © 2010 Green Supply, LLC

• Energy efficiency of lights = Light output (lumens (lm)) / Electric power (watts (W)) • Higher the ratio, more energy efficient. • L Less power required t generate li ht output. i d to t light t t Type of Lights Energy Efficiency LED Light 80 to 110 lm/W Incandescent 14.2 lm/W Fluorescent 60 lm/W © 2010 Green Supply, LLC

• LED light most energy efficient • With same light output, LED light bulb consume output – 87% less electricity than incandescent – 45% less electricity than fluorescent Incandescent Fluorescent LED Light Electricity consumed © 2010 Green Supply, LLC

• Reduce 1/3 of U.S. electricity use for lighting by 2030. – Save 348 billion kilowatt hours hours. 2008 Electricity Use 2030 Electricity Use 13.40% 4.47% 4 47% Lighting Lighting 86.6% 86 6% Other 95.5% 95 5% Other Oth • 1/3 less electricity use = less power plants – Eliminate 44 1000-megawatt power plants • Less power plants = less greenhouse gas emissions – Eliminate greenhouse gas emissions equivalent to 47 million cars.

• LED light reduce your electricity bills • H How much savings i electricity bill? h i in l t i it Based on $0.15 per kWh electricity rate and 35,000 hours operation (average life of one LED light bulb) Light Output LED Light Incandescent Electricity Bill (Based on Bulb (from Green Electricity Bill Savings Using incandescent with Supply) pp y) these wattage) LED Light Electricity Bill Bulb 25W $15 75 $15.75 $131 25 $131.25 $115.50 40W $26.25 $210.00 $183.75 60 W $36.75 $315.00 $278.25 100W $63.00 $525.00 $462.00 © 2010 Green Supply, LLC

• LED lights are non-toxic and recyclable. • Fluorescent lamps contain mercury – Mercury is highly-reactive, toxic heavy metal when inhaled or highly reactive ingested can cause damages to central nervous system, brain, kidney, reproductive systems and even lead to death. – Fluorescent lamp need to be disposed properly as hazardous waste. – Compact fluorescent light bulb contain 3 to 5 mg mercury. – Fluorescent tube light (4 foot long) contain 12 mg mercury (4-foot mercury. © 2010 Green Supply, LLC

• Longer operation: – LED light bulb: Average 35 000 to 50 000 operating hours 35,000 50,000 – Incandescent light bulb: Average 1,000 operating hours – Fluorescent light: Average 10,000 operating hours g g g • Reduce waste with longer operation: – 1 LED light bulb last 35 times longer than incandescent and 3.5 times longer than fluorescent – Less LED light bulbs in landfill!
