One of the greatest pushes by governments is to GO GREEN, for the benefit of the children.What governments are NOT doing is providing unbiased information to the general populous, regarding global warming trends, and in general the REAL cost to the consumer for such power saving goods.
In this post under scrutiny is the power saving down lights, governments and businesses are pushing so much.
Two types of MR16 (low voltage - 12V) globes have been selected for analisys.
A 12 Volt, 3 Watt downlight 30 degree light, 30000 hrs life span compared to a 20 Watt, 60 degree, 3000 hrs globe.
The 3W globe costs $49.95, or in a kit with transformer for approx. $91, whereas the 'noname' 20W globe costs $1.00.
In Australia, currently electricity costs approximately $0.21 per kwhr.
The 3W globe consumes 0.004 kwhr or 0.084 cents per hour.
The 20W globe consumes 0.020 kwhr or 0.42 cents per hour.
The LED globe is approximately 5 times cheaper to run than the halogen equivalent.
According to the manufacturers information, the LED globe lasts approximately 10 times longer than the halogen.
The LED globe is approximately 50 times more expensive than the halogen.
In an Aussie home with approximately 70 downlights, the total cost of the fit out will be worth approximately $3500, compared to the $70 for the halogens.
LED downlights give out less light (lumens) per watt than their halogen counterparts. A 3W LED gives approx. the same amount of light as a 10W halogen.
On www.cromptonlighting.com there is NO indication of their product pricing.
It is NOT cost effective to run these LED globes, even if the price difference was 25 times rather than 50 times.
