Compact Fluroescent (CFL) will soon exit the market under the increasing building efficiency regulations. With uncomfortable light reproduction and questionable mercury content this comes not a moment too soon.  LED has entered the market. Commercial applications are taking this technology up purely for cost and efficiency reasons. It makes sense.

But how many cents?

A typical 35W hallogen will cost $22.05 to run for 1 year at 12 hours a day 7 days a week 50 weeks in the year. At 15c kWhr that same duration will cost $4.41 with a 7W LED.

In a commercial application that is $17.64 saving per year per lamp.

In a domestic application that is $6.61 saving at 6 hours (half) per day.

With an expected lamp life of 5-10 years these lamps present a power saver combined with lower maintenance.  If youre looking to retrofit your own lamps - have a look at the range from primoLED
