Statistically, lighting accounts for around 20 to 50 percent of total energy consumed in homes and offices. And from the cost perspective, a single 100W light bulb used just 6 hours a day can cost over $25 per year to use (.12/kWh). But on the ‘brighter’ side of affairs in these critical times, there have been many ingenious alternatives for energy usage in lighting. And one of these adroit conceptions is the Secret Lamp designed by Choi Jongwoo.
Basically contrived to address the problem of energy wastage, the lamp actually caters to duality of contexts. First, when the contraption is switched on (from a direct electrical outlet), one can adjust the amount of light by controlling the attachable as well as detachable flap, covering the cylindrical light facade. We can control the flap by just literally peeling it off the surface, as a magnetic mechanism (at the corners) holds the remaining part on to the light.
Secondly, as a secondary attribute, the lamp will be given a much tepid ambiance of a cyan colored night glow once it is switched off and the whole cover cap is taken off. This ‘glow’ results from the power being imparted by the charging of the 5000mah battery system during the conventional mode. The batteries can be charged using a 5V input and output. So, this mechanism conveniently allows us to enjoy the light that we have previously spent with the ‘on’ mode; in the process accentuating upon the saving of total energy quotient.
