The key strength of LED lighting is reduced power consumption.
When designed properly,an LED circuit will approach 80% efficiency,which means 80% of the electrical energy is converted to light energy.The remaining 20% is lost as heat energy.
Compare that with incandescent bulbs which operate at about 20% efficiency (80% of the electrical energy is lost as heat).
In real money terms,If a 100 Watt incandescent bulb is used for 1 year,with an electrical cost of 10 cents/kilowatt hour,$88 will be spent on electricity costs.Of the $88 expense,$70 will have been used to heat the room,not light the room.If an 80% efficient LED system had been used, the electricity cost would be $23 per year-there would be a cost savings of $65 on electricity during the year.
Realistically the cost savings would be higher as most incandescent light bulbs blow out within a year and require replacements whereas LED light bulbs can be used easily for a decade without burning out.

Advantages of LED bulb
There is no comparison between the cost of LED lights vs.traditional incandescent options.
With incandescent bulbs,the true cost of the bulb is the cost of replacement bulbs and the labor expense and time needed to replace them.These are significant factors,especially where there are a large number of installed bulbs.For office buildings and skyscrapers,maintenance costs to replace bulbs can be enormous.These issuses can all be virtually eliminated with the LED option.
Why our LED bulb
╚ long last lifetime up to 11 years continous opteration
╚ standard warranty 3 years
╚ perfect thermal management
╚ replacement for 25w incandescent bulb
