LED Lights – The Benefits
Why use LED lights?
• Energy Efficiency: LED lights use 80% less energy than incandescent lights.
• LED's use less wattage to achieve the same level of brightness. (100w incandescent bulb = 15W LED)
• New Zealanders spend 12% of their power bill on lighting in their homes, LED lights would reduce that spend up to 2.5%.
• LED lights last for at least 20 years. You don't have to change them as often, making them hassle free.
• Safe around insulation: LED's generate a lot less heat, therefore LED light fittings can be installed right next to, or covered by, insulation.
• Environmentally friendly: They don't contain mercury unlike CFL (compact fluorescent lamp) lights.
• LED's turn on straight away to their full brightness, unlike CFL lights.
• Payback period: 6 months to two years.

Lighting types that can utilise LED bulbs:
• Recessed lights
• Outdoor lights
Types of LED light bulbs available on the market
• Standard bulb (screw and bayonet bases)
• Reflector bulbs
• Security lights and exterior floodlights
• Spotlights (MR16 & GU10)
For this example, we will compare two standard screw-in light bulbs, and one 10.5W LED bulb, which is the equivalent to a 125W incandescent bulb.
10.5W LED $16.59
100W Incandescent $0.97
If both bulbs were running for 3 hours a day, ever day of the year, your price per kWh is $0.30.
10.5W LED - $3.45 (running cost per year)
100W Incandescent - $32.85 (running cost per year)
The initial investment to buy the LED light would be paid off within 7 months.
LED lights come in a variety of colours. Typically, household lights have two main options, warm or cool. Warmer lights tend to be picked for bedrooms, they emit a relaxing hue that is similar to a sunset or a fire. Cool lights can be useful in practical areas of the home, such as kitchens or home offices.
Colour Rendering Index (CRI)
Different LED lights will have a different CRI rating. The CRI is scaled from 0 to 100, indicating how accurately the light source will render a colour.
The closer the CRI is to 100, the higher the quality. Low CRI lights, 80 or less, will make furnishings or paintings look washed out.
