movie-iconWhen big LED signs with “Stop” on it aren’t enough, then you have to

LED hits 200lm per watt mark

While light emmiting diodes did not gring up much light in the past, today’s
LEDs have great potential to replace the energy-saving lamps which are in
conflict with a environment-friendly production. As Energy lamps still have
small amounts of toxic mercury and light-emmiting gases inside…

What thrilled the whole world last year seems to have been finally put back to

Einstein’s theory of lightspeed falsified?

You all know the theory that light is the fastest possible “element” existing.
Albert Einstein has described in 1916 that nothing can be faster than the

dangers and other obstacles on the road or when something important is broadcasted on
