dramatic reduction on electrical bill from leds
Here's a phenomenal story about the virtues of high technology!
I just replaced all of the lighting in the house with either LED bulbs and/or three purpose-built LED ceiling fixtures. I also replaced two halogen floodlights on a motion detector with LED floodlights. Below is the average daily usage for this year and last year, for the same period of time copied straight from my power bill:
Average Daily Usage Current Last Year
Electric (kWh) 70 74
Average Daily Temp (* F) 38 42
You might think, "4 kWh less electricity per day isn't anything to write home about." And you would be correct if that was the whole story..........
However, last year the control panel on our outdoor hot tub frizzed out and the old cover was waterlogged and torn so we didn't even have the hot tub turned on during the same period of time, and had drained it out completely to prevent freeze damage in September 2012! When the jets are running or the heater is heating this hot tub draws 220 volts, like a clothes dryer. We keep the water temperature at 104 degrees.
This year, the hot tub is up and running again after I replaced the circuit board and had a new custom built high density-foam cover made.
Essentially, the change in lighting from all Incandescent to LED allows us to run an electrically-heated hot tub in the dead of winter for free, which is quite a bit more electricity that you could ever dream of generating using solar collectors.
Notice also the temperature averaged four degrees colder THIS year over last year, and this house is electrically heated and electrically water heated.
Disclosure: I also replaced the thermostat with one of those high-tech Next thermostats ($300 from Amazon). Also the hot tub cover is made of high-tech high-density super-insulating foam and fits much tighter than the old one, even when the old one was in good shape.
For once, a government mandate, this for improved lighting energy efficiency, is a good thing.
Your mileage may vary.
