The mercury lamp is generally used in the place in which it should brightly shine on at night such as factories and parking lots.
Because the luminescence principle of the mercury lamp is almost the same as the light bulb, power consumption considerably becomes it, too.
It is hot to do the burn when lighting for a long time.
Being designed by thinking about the conservation of energy of this lighting is LED lighting.
Power consumption becomes about 1/10 when the LED lighting is compared with the mercury lamp, and brightness hardly changes.
It is possible to make it more brightly if it increases the number because brightness can be supplemented with the number of LED at the LED lighting.
Let’s think about about 80W of the mercury lamp assuming that it is general.
If it is lit all the year round, it becomes a calculation to which it costs as much as 200,000 yen.
There are as much as 200,000 yen and the origin can be taken easily though the unit price of the LED lighting is high.
The energy-saving effect, it is preeminence.
Moreover, time and the cost of the exchange can be greatly reduced because it is long-lived.
Because the mercury lamp set up in the factory and the parking lot is installed in height, the exchange is not easy either.
Considerable years have passed since global warming begins to have been shouted.
The technology of LED has advanced greatly between those.
It was too dark to use it as a lighting before.
High luminance LED comes to be sold recently, and it steals the limelight suddenly.
The price cutting is expected by mass-produce advancing though a present unit price is high.
Still, it is thought that it is a matter of time though it doesn’t say to the place in which it uses it by the ordinary family.
If you are using the mercury lamp, will you think about the LED lighting?
