LED flashlights seem to get brighter every few years. Fortunately, the price also seems to be coming down on these super-bright devices that are power-efficient. What's more amazing about LED technology is the low amount of heat generated by such bright lights.
Well, electrical engineering researchers at the University of Hong Kong seem to have found a way to develop brighter LED lights. What's the secret? Answer: hexagonal-close-packed microspheres. These scientists may have found a way to make even brighter LED lights! So how bright do you think those keychain flashlights can get?
