Healing the Earth – one light at a time

CO2 EMISSIONS BY LIGHT SOURCE

Global warming is the most pressing environmental issue of this century. What does this have to do with how we choose the way we light up our world?

US government statistics- power plants in the US produced 2,459,000,000 tons of carbon dioxide (CO2) in 2006. Almost 32% of the electricity they generated was used for lighting.

Get serious about fighting global warming… Make lifestyle choices that will reduce our greenhouse gas emissions. Most significant thing you can do…simple as L.E.D. Replace traditional lights* with an LED lights Reduce our carbon dioxide emissions by 27.4 million metric tons of CO2 per year! 3 x more carbon dioxide than Costa Rica gives off in whole year.**

Global Warming

Global Warming

LEDs contain NO Mercury - Florescent Lights Do

49% of the electricity in the US is produced from coal fired power plants. Besides CO2, power plants emit hazardous substances including: Mercury, Nitrous Oxides, Sculpture Oxides, and others.

LEDs for lighting = 80% less electricity = 80% less substances contaminating our environment = 80% less contact with us.

LEDs last 60 x longer than incandescent lights and 10 x longer than fluorescent lights = less waste = less replacements.

LEDs don’t waste energy as heat = electricity you use for air conditioning inside.

* All data and statistics are derived from publicly available data from the source for official energy statistics from the US government.

LED Lamp Features

Ecology – Reduces Global Warming.

Economy – 80 + % less power consumption than traditional lights.

Extended Life Rated at 50,000 hours which translates to 10 + years maintenance-free product life.

Eliminates - Glare, and night blossoming outside… Stops light pollution!

Excellent Luminosity Ultra bright, cool white light close to daylight quality, provides bright white light which

improves color rendering and improves night visibility to 300% over traditional light sources.

Cost Saving Save up to $280 per year per light, 2,300 over the product’s lifetime.

GHG (Co2) Reduction - 768.2 lbs/yr; 10,574 lbs over the lifetime - as much Co2 as the average passenger car

produces in 11 months of driving. *(Based on 1.55 lbs Co2 per kwh, 11,560 lbs Co2 per passenger car per year)

Easy Installation – Modular construction and mounting.
