Comparison Chart  LED Lights vs. Incandescent Light Bulbs vs. CFLs Energy Efficiency & Energy Costs Light Emitting Diodes (LEDs) Incandescent Light Bulbs Compact Fluorescents (CFLs) Life Span (average)  50,000 hours  1,200 hours 8,000 hours Watts of electricity used  (equivalent to 60 watt bulb). LEDs use less power (watts) per unit of light generated (lumens).  LEDs help reduce greenhouse gas emissions from power plants and lower electric bills 6 - 8 watts 60 watts 13-15 watts Kilo-watts of Electricity used  (30 Incandescent Bulbs per year equivalent)  329 KWh/yr. 3285 KWh/yr. 767 KWh/yr. Annual Operating Cost  (30 Incandescent Bulbs per year equivalent)  $32.85/year $328.59/year $76.65/year Important Facts Light Emitting Diodes (LEDs) Incandescent Light Bulbs Compact Fluorescents (CFLs) Sensitivity to low temperatures None Some Yes - may not work under negative 10 degrees Fahrenheit or over 120 degrees Fahrenheit Sensitive to humidity No Some Yes On/off Cycling   Switching a CFL on/off quickly, in a closet for instance, may decrease the lifespan of the bulb. No Effect Some Yes  - can reduce lifespan drastically Turns on instantly Yes Yes No - takes time to warm up Durability Very Durable - LEDs can handle jarring and bumping Not Very Durable - glass or filament can break easily Not Very Durable - glass can break easily Heat Emitted 3.4 btu's/hour 85 btu's/hour 30 btu's/hour Failure Modes  Not typical Some Yes - may catch on fire, smoke, or omit an odor Light Output Light Emitting Diodes (LEDs) Incandescent Light Bulbs Compact Fluorescents (CFLs) Lumens Watts Watts Watts 450 4-5 40 9-13 800 6-8 60 13-15 1,100 9-13 75 18-25 1,600 16-20 100 23-30 2,600 25-28 150 30-55 Environmental Impact Light Emitting Diodes (LEDs) Incandescent Light Bulbs Compact Fluorescents (CFLs) Contains the TOXIC Mercury  No No Yes - Mercury is very toxic to your health and the environment RoHS Compliant Yes Yes No - contains 1mg-5mg of Mercury and is a major risk to the environment Carbon Dioxide Emissions  (30 bulbs per year) Lower energy consumption decreases: CO2 emissions, sulfur oxide, and high-level nuclear waste.  451 pounds/year 4500 pounds/year 1051 pounds/year
