Philips new amazing led light bulb
Made by Dutch electronics giant Philips, the bulb swaps filaments for light-emitting diodes to provide illumination.
Using LEDs endows the light with a long life and a hefty price tag. The first versions are set to cost $60 (£37).
Philips has arranged discounts with shops that will sell the bulb meaning some could buy it for only $20 (£12).
