If you're into camping, festivals, hiking or any other outdoorsy activity you'll need a drinking bottle and a lamp. But why take both when you can take the ingenious LightCap? (Don't worry, that's a rhetorical question so you needn't start racking your brains).

This dual-purpose lantern/bottle has been designed to refresh and illuminate at the same time. How? Simple, its lid contains a sealed unit housing a solar panel, Ni-Cad battery pack and powerful LED light. Brilliant, eh?

Weighing in at only 312 grams with a 1 litre capacity, the virtually unbreakable LightCap is ideal for camping trips, especially when backpack-space is tight. Just think, armed with this eco-friendly device you can enjoy a good glug, go a wandering after dark and illuminate your tent without messing around with a separate light.

Best of all a handy waterproof switch on the cap lets you change from the bright white LED to a more relaxing red one. Apparently this preserves energy but we use it to replicate that bridge-of-the-Enterprise-red-alert feel. ('Cap'n, ma dilithium crystals cannae take it!').

Talking of preserving energy, a four-hour 'charge' of sunshine will keep the LightCap shining for hours, so you can go about your night-time business without fumbling around in the dark (unless you want to). And those of you planning an extended trek won't have to worry about ordering a replacement LightCap from the depths of the jungle as the rechargeable batteries will last for at least 300 cycles.

Whether you're planning a road trip, festival weekend, backpacking trek or you've simply forgotten to pay the electric bill, the Sollight LightCap is the perfect night-time companion. So hit Buy and stay refreshed and illuminated wherever you may roam. Night night.
