"Turn off lights, and turn on LED lamps ...." What is the real purpose for doing it? Is that switching to LED lamps the purpose? What we have to do right now is that to care for the earth. In order to do so, we have to save energy and reduce unnecessary waste. In addition, to review our lives is the paramount issue. We have been so particular about the brightness for long. As a result of this, our sensitivity was clouded. Why do we reset our sensitivity for now? We all embrace sense of familiarity with the unit that has been used to represent intensity of lights. However, the new light has a structure that is of a different dimension. The LED we use differs fundamentally in terms of structure from conventional light which has a structure to achieve brightness by burning objects (represented in the unit of 40W, 60W or 100W). The biggest advantage of switching to LED lamp is that electric power consumption is low. Forgetting about this great advantage and still hoping for over-the-standard brightness which was set in the past is like putting the cart before the horse. When you are considering “Energy saving/Ecology/Safety” which is the original purpose of switching to LED lamps, you will also consider how to obtain just enough brightness without any interference with your daily life, with LED lamps which consume less electric power. You will select lamps which match the concept of ”Proper lighting for Proper places”, which is the best choice to select LED lamps.
