LED vs Halogen Downlights

As an estimate, here is how the energy saving equation looks for replacing halogen downlights with LED alternatives:

  • 25 Halogen Lights using 50W each = $857.90
  • 25 LED Lights using 9.5W each: = $151
  • Annual saving of LED down lights vs halogen = $706.90

As you can see that is a great saving and usually pays its self-back in the first year. LED also have a longer life than Halogens you won’t need to replace them.

MacDonald Air and Electrical have recently installed a split system air conditioning unit at my property. They were very helpful explaining what was needed and provided a very competitive quote. They arrived at the agreed time and cleaned up any mess from their work before they left. I was very happy with their service.
