Replacing Halogen down lights with LED. Costs and photos
We just have 2 halogen down lights in our house, but I would like to use them more often that we do.
I bought a few and replaced them. They work well for lighting up the stairs. The light is more blue than the halogens but OK for here.
I tried some at a friends place with electronic transformers and they don't work. The transformers probably detect no load and shut down.
So, How much can I save?
The test voltage was 13.65v
LED Current 0.31A
Halogen Current 4.2A
At 240v with say 90% efficient transformer this equates to:
LED: 4.65W ~ 20mA @ 240V
Halogen: 63W ~ .263A @ 240V
At 30c/kWh this amounts to:
LED ~0.014 cents per hour
Halogen ~ 0.19 cents per hour
Difference is .176 cents per hour. At a cost of 9$, payback is in 5113 hours or 213 days.
This might not seem much, but the lighting energy is now 7% of what is was. I call this significant.
One of each:
After with LEDs.
