Today LED lights have become very popular in a short time after Fluorescent lights became popular too. Our question is how energy and Eco efficient are LED lights compared to Incandescent classic light bulbs  and compared with Fluorescent lights.

I will start with each time of light properties.

Properties

Light Emiting Diodes (LEDs)

incandescent lampIncandescent Light Bulbs fluorescent lampCompact Fluorescent Lights (CFLs)
Life Span None May not work if there are -10 and +50 degrees Celsius May not work if there are -10 and +40 degrees Celsius
Humidity Sensitivity None If water gets inside Yes
On/Off Cycling No Effect Some Yes, lifespan is drastically reduced
Durability Can easy handle jarring and bumping Made of glass or filament, can break very easy Glass, can break very easy
Heat Emitted 3.4 btu’s/hour 85 btu’s/hour 30 btu’s/hour

 

Energy and Efficiency Also the Costs

Temperature Sensitivity 50,000 Hours 1,200 Hours 8,000 Hours
Watts of Electricity used 6 – 8 watts 60 watts 13 – 15 watts
Kilowatts/Year 329 KWh/yr. 3285 KWh/yr. 767 KWh/yr.
Annual Costs $32.85/year $328.59/year $76.65/year

 

Eco and Toxins

Toxic Mercury No No Yes
RoHS Compliant, Yes is good Yes Yes No – contains 1mg-5mg of Mercury and is a major risk to the environment
Carbon Dioxide Emissions, Lower is better 451 pounds/year 4500 pounds/year 1051 pounds/year

 

Beside the toxins that are released from lights, we can add the toxins emissions of the light bulbs production.mercury impact of light bulbs

Light Output Power

1,100 9-13 75 18-25
1,600 16-20 100 23-30
2,600 25-28 150 30-55

 

Final Conclusion

I tried to compare almost everything between these three types of lights, we can add that the design of the LEDs is directed in one direction. Making LED more efficient comparing to other type of lights.

Bellow you can see a test where the light at the door has the same brightness. At these three doors is used a 10 watts Led bulb versus 100 watts Incandescent bulb versus 15 watts Fluorescent light. We can clearly see that LED uses much less power and energy..
