• 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.positive to negative junction.

• Green qualities of LED lights:– High energy efficiencyHigh energy efficiency– Non-toxic– Reduced wasteReduced waste
• Excellent color quality• LED light comes on instantly• LED light comes on instantly• Emit less to no heat

• Energy efficiency of lights= Light output (lumens (lm)) / Electric power (watts (W))
• Higher the ratio, more energy efficient.L i d t t li ht t t• Less power required to generate light output.
Type of Lights Energy EfficiencyLED Light 80 to 110 lm/WLED Light 80 to 110 lm/WIncandescent 14.2 lm/WFluorescent 60 lm/WFluorescent 60 lm/W

• 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 lights are non-toxic and recyclable.
• Fluorescent lamps contain mercuryMercury is highly reactive toxic heavy metal when inhaled or– Mercury is highly-reactive, toxic heavy metal when inhaled or 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– Fluorescent tube light (4-foot long) contain 12 mg mercury.

• Longer operation:– LED light bulb: Average 35 000 to 50 000 operating hours– LED light bulb: Average 35,000 to 50,000 operating hours– Incandescent light bulb: Average 1,000 operating hours– Fluorescent light: Average 10,000 operating hoursg 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!
