I think, therefore I am able to light up the room. Imagine if Descartes had come up with that. Rather than pondering the meaning of existence, he could have illuminated most of France. But then, he didn't have a computer with a USB port. You do. Just plug this lightweight little number in, type away furiously, and watch the light respond to the way you bash the keyboard. The faster you type, the brighter the light. Type. Light. Type, type. Light, light. Get the idea?

It's simply spiffing if the boss is prowling around towards the end of the day - your light can be a beacon of peak activity, marking you out as someone deserving a productivity bonus, not to mention an MBE. Super-bright LED technology in the light's base produces no fewer than five different levels of intensity, enabling you to be a veritable human torch, simply eating work and guiding distant shipping to safety. Not to mention proving conclusively what an all-round, team-playing clever-clogs you really are.
