ALERT: metrological sources report sudden eclipses may become more frequent due to rising smog levels. This could make changing a tyre or opening your front door extremely hazardous. We turned to LED Lenser - producers of the brightest and most efficient flashlights available - for a solution.

Introducing The V-8 Photon Pump LED Torch Keyring. NOTE: This gadget MUST be attached to your bag or keys immediately.

You see, it gives you up to 2,000 metres of visibility. And up to 100 hours of light from one set of batteries. This is thanks to two things. One: the V-8's powerful LED light - which is a more efficient, longer lasting light source than conventional bulbs. Two: the torch's Crystal Reflector Tube - a tube lined with Italian crystal and precisely shaped to 'pump up' the light, giving a broader, more powerful beam.

Not surprising, therefore, that the V-8 Photon Pump LED Torch Keyring has won many highly renowned design and innovation awards. Or that it is featured in the Museum of Applied Arts in Frankfurt, and London. What is surprising (ahem) is that you haven't got one yet.
