How Energy Saving Lamps can save your cost ?

Saving Precious Dollars
Although the initial cost of a compact fluorescent lamp is usually higher than that of an incandescent bulb, the cost is quickly recovered because Empro compact fluorescent lamps (CFLs) use between 75% and 80% less energy, depending on the model, than similar standard bulbs. For example, by replacing a standard 60-watt incandescent bulb with an e-ball 14-watt CFL, up to $46 in energy costs can be saved over the life of the CFL1. Furthermore, CFLs generate 75% less heat than standard incandescent which can help reduce air conditioning costs.
