LEDs (Light Emitting Diodes)

You can change your lighting and start saving immediately!

What’s the difference between light globes?

It can be confusing choosing between the different types of light bulbs. It’s important to choose the light bulb which will cost you least over the long run. Here is an overview of the main types:

Even though LEDs can cost you more initially, a good quality LED is cheaper in the long run!

What are LEDs?

LED stands for Light Emitting Diode. LEDs consist of a collection of small solid light bulbs that are extremely energy efficient. They convert 60% of their electricity into light, compared to only 5-10% for CFLs. LED bulbs also last about 25 times as long as incandescent globes, and up to 10 times as long as CFLs  – it simply makes sense to switch and save!

What types of LEDs are available?

There is a whole range available for different lighting applications and different lighting fittings. Most types of lights are now available in LED.

How do I choose the right brightness?

Firstly, remember to think lumens, not watts. With the new energy-efficient light bulbs available, light bulbs now produce the same amount of light using far less power. So it’s important to use ‘lumens’ to select the best light for you.

Lumens Watts (Incandescent) Watts (LEDs) Watts (CFL) Use
420 40 6 7 Suitable for a table or floor lamp
800 60 8-10 12 Suitable for a small room
930 75 10.5 15 Suitable for a medium room
1300 100 13 20 Suitable for a large room

I thought it was best to remove the existing transformers?

Earlier, LED downlights often interfered with transformers (which ensure the correct voltage of electricity was put into the light), meaning that it was advisable to remove the transformers, before replacing the globes. LED technology has advanced in the last 2-3 years, meaning that this is no longer the case in most households. However, in some cases, you may find that your transformers are not compatible with certain LED downlights. If you’re not sure how to best proceed, feel free to give the Positive Charge team a call on 1300 339 915.

Are LEDs warm coloured lights?

LEDs are now available in all ranges of colour you may want for your home.

The Kelvin temperature scale ranges from 2700K to 6500K. Within that range are a variety of colour temperatures including:

  • Warm White Light ranges from 2700K to 3500K. This produces a calming and relaxing light that is great for bedrooms, living rooms, and dining rooms.
  • Natural White Light is in the 3500K to 4500K range. Cool and clean, this LED colour most closely mimics sunlight, which makes it good for use in almost any location. Basements, garages and other dark places that don’t have a lot of natural light are a good place for cool white LED lights.
  • Daylight White Light ranges from 5000K-6000K. This is a crisp and clear white light that is great for garages, security lights, offices, or retail locations.
  • Cool White Light is between 6000K and 7000K. These are good in commercial locations or any situation in which you want to foster alertness.

Why get a professional to change my lights?

Old style halogen downlights have a transformer in your ceiling cavity. If you get these lights replaced by a qualified electrician then they will remove the transformer completely and install the new LED lights for you. A qualified electrician will provide you with a certificate of compliance, a warranty and (if you go through a reputable company) they will claim any rebated on your behalf.

So why not do it myself?

If you want to simply buy LED light globes from a shop and replace them yourself this is fine. There are now many styles of globes to fit all kinds of fittings, including halogen downlights and can be put in without removing the transformer.

Do I need to get Strata or Owners Corporation sign off?

If you own the apartment, you can change your light fittings to LEDs, however you may need permission from the owners corporation to change recessed light fittings. If you are a renter, you need to get approval from your landlord.
