Just recently, the UK phased out 100 watt light bulbs in support of the usage of eco-lighting available today. Unfortunately, the shift was not met without its own dose of criticisms due to complaints against CFL bulbs. LED would have been a better alternative, but high prices have discouraged its widespread use. This new technology of gallium nitride (GaN) LED lighting from the UK however, has the potential to make LEDs a household fixture. There have been some issues regarding cost with using gallium nitride for LEDs in the past, but the scientists from Cambridge University-based Centre for Gallium Nitride were able to find a way around it. This new generation of GaN LED lighting promises to be three times more efficient than commercially-available fluorescent lighting. They can also last 100,000 hours, which is around 10 times as long as fluorescent lamps, and would cost $3 a pop. The bulbs do not contain mercury like CFL bulbs do, do not flicker (a problem with CFLs many associate with migraines and epileptic fits) and reaches maximum brightness as soon as they’re switched on. According to the scientists, if we’re going to base it on the current results from tests, installation of the bulbs in all UK households could lower energy consumption for lights from 5 to 20 percent.
