LED lights
Hello everybody,
I've read some of the comments and there are too many to respond to individually. This is not a solution to inverters by themselves, but more of a holistic approach.
Why not change to LED lights? First you will reduce your electricity bill under normal use, and when you do have load shedding, your inverter will last longer because the LED lights won't drain your batteries as quick.
LED lights have come a long way in the last few years as far as brightness is concerned.
Please go to
www.c2r.co.za
to have a look at the range that is available in SA.
For example a fully dimmable fluorescent replacement tube that does not need a starter and ballast to work, although they will work with them. Or a fully dimmable globe.
6 Watt downlighters that give the same light as a 50 Watt halogen, in either the 12v or 220v versions. A 88% saving in electricity. The 12v version is dimmable because of the transformer.
There is also a 2 Watt downlighter that looks the same as the name brands from hardware stores, but this version gives more light, I have put them side by side in my bathroom. A 96% saving in electricity.
The lifspan is amazing:
Tube replacement is 80 000 hours.
6Watt downlighter is 30 000 hours.
BulbLED is 40 000 hours.
A little something to ponder: we have to stop thinking of LED lights as consumable items. Like toilet paper, we use it, its finished, we buy more. Same as tungsten and CFL lights, because their lifespan is so short. NOT LED's.
The calculation is as follows:
Using a bulbLED (http://www.c2r.co.za/html/bulbs___do...s.html)(scroll down) outside your front door, at 40 000 hours for a LED, at 10 hours/day, 7 days/week = 10 years.
Now using a bulbLED as a bedside lamp at 1 hour/day, 7 days/week = 100 years.
Your grandchildren will use the LED's that you will buy.
Look at your light use habits at home, analyze what lights are on for longer periods
than other lights. Change the longer ON lights first, that will have the bigger, more immediate impact in reducing your electricity bill.
The more hours per day lights burn, the better LED's become.
The higher the Rand per KW hour is, the better LED's become.
Look around at night, how many lights are on. Chop that by 50%. Imagine that right now! Then put in occupancy sensors, that switch the lights off when nobody is around.
We have them, but they are very new to us. Watch the website for them.
Now combine LED's and occupancy sensors. Imagine that electricity saving!
Yes they are expensive, but calculating a total cost of ownership
the lights will save you money in the end.
For the environment friendly people, remember
that LED's contain NO Mercury.
Imagine SA wihout any loadshedding.
Applications exist for any situation, Industrial, Commercial,
Residential.
