The accepted formula for costing electricity by B.C. Hydro
is: # watts x # hours /1000 = # kilowatt hours x rate (.06)
Therefore, if we average the daily wattage to 850 watts, and
an average of 12 hours light per day, it would cost: 850 x 12 / 1000 = 10.20 kilowatt hours x .06 = 61 cents per
day or $222.65 per year.
**NOTE** This does not take into account the replacing of bulbs.
If this incandescent system had to be installed, the average
cost would be $150.
Over the 10 year warranty period of SunScope, it would cost $222.65 x 10 = $2226.50 to provide the same amount of light.
SunScope wins hands down in this comparison. As well, the quality
of natural light vs. artificial light is healthier and less
shadowy. The SunScope is energy free and less expensive.
Widespread use in home and office can reduce power plant
emissions more than any other day lighting product.
