Those who reckon that LED lights cannot spread enough light in your four boundaries, their minds need a dialysis. The news is that researches has lately discovered a way of making LED lights much more brighter without eating additional power.

This would happen by digging microscopic holes within the shell of the LEDs, thereby increasing their brightness by consuming same energy. A technique called nano-imprint lithography is being identified by the researchers at the University of Glasgow that would enable them to engrave minuscule holes on to the LEDs, permitting more flow of light. Besides respecting the energy consumption, LEDs are much smaller and have a long life.
