Philips Wake-up Light

£135 philips.co.uk
Start each day with the warmth, light and natural sounds of an African sunrise without spending the night being menaced by leopards. The Wake-up Light also has a USB input so you can be roused by the gentle strains of Pantera if you prefer, while the lamp gradually cranks your chamber from dark to light (up to 250 lux). It also works in reverse, gradually fading you into slumberland.
