Saving Energy in Your Home With Lighting -
Choosing the right lighting for you home
Choosing the right lighting in your home, with higher energy prices constantly rising,
we are all becoming more educated in the ways we can save energy in our homes. One
of the most cost-
Incandescent light bulbs
Incandescent bulbs are now becoming a thing of the past this is particularly the
case in the UK where these types of bulbs are being completely phased out. Incandescent
bulbs are not very efficient with approximately 95 percent of the energy consumed
wasted as heat and have an average life span of 750-
Compact fluorescent light bulbs (CFL)
Although there are some negative comments made about compact fluorescent light bulbs they are an improvement on the outdated incandescent bulbs and emit the same light quality. Compact fluorescent light bulbs have a K number listed on the packaging the higher the K or (Kelvin) number the brighter the light. These types of bulbs are four times more efficient than incandescent, last 10 times longer approximately (10,000 hours) and use up to 80% less energy.
What to look for when you shop for light bulbs.
Degrees Kelvin (K) Scale
Number of lumens (lm) produced by common incandescent bulbs
150 watts = 2600 lumens
100 watts = 1600 lumens
74 watts = 1100 lumens
60 watts = 800 lumens
40 watts = 450 lumens
Warm White, Soft White
The standard colour of incandescent bulbs
2700 k -
Cool, Bright White, Neutral
Good for kitchens and workspaces
3500 k -
Natural or Daylight
Good for living rooms and lamps
Light emitting diode bulbs (LED)
Light emitting diodes consist of a number of (LEDs) to emit light, although they can cost a little extra than the cost is balanced with the increased life span and the higher energy efficiency. light emitting diodes can last up to 10 times longer than compact fluorescent on average 25,000 to 60,000 hours plus.
Halogen light bulbs
When compared to compact fluorescent or light emitting diodes, halogen light bulbs are not as efficient although there is an improvement to the standard incandescent light bulb. Halogen light bulbs have a life span of approximately 2,000 hours and are around 50% more efficient than incandescent bulbs.
Most energy efficiency light bulbs available cannot be dimmed using a standard domestic dimmer. However, since 2007, new dimmer enabled energy bulbs became available and can be dimmed with a standard dimmer switch. Please check to ensure that you are purchasing the correct item before using an energy efficiency bulb with a dimmer switch.
Wind turbines produce electricity utilising the power of the wind. Small systems
known as 'microwind' or 'small-
Solar powered electricity systems, or solar photovoltaic's (PV) catch the sun's energy using photovoltaic panels. The cells in the panels convert the light into electricity, which can be used to run household appliances and lighting.
Over a third of all the heat which escapes from an insulated home is lost through
the walls. Installing wall insulation is one of the most cost-
The Plans are Easy to Read and Follow
One Unit Generates at least 1,000 Watts of Power
The Wind Generator Can Be Built for Under $100
The Turbines are Easy to Build and Assemble
The Most Powerful and Most Efficient Way To Generate Natural Clean Electricity Was Discovered In 1901! But When “BIG ENERGY” Realised They Couldn’t Meter It And Charge YOU For It! They Buried The Discovery And Had The Government Label It As “CLASSIFIED”
