If you’ve visited a DIY store or two recently you may have noticed a growing trend in self-powered garden lighting, pathway outliners, fairy-lights and tree lights etc.

It’s the latest ‘in thing’ for your night-time soirees and barbeques. However, most of the lights you’ll see are solar powered, charging their batteries during the day and switching on their lights when it gets dark. Which is brilliant, of course, but they do run down eventually and they can get a bit dull to look at after a while…

So that’s where these amazing Firewinder lights come into their own. You hang them off tree branches, posts or whever you like and the wind makes them spin around, which genertes electricity and makes an array of LED bulbs glow in a swirling pattern – day or night – pretty much forever so long as there’s at least a breeze.

The effect is pretty awesome, we’ve had a bunch of them at two parties so far and they always get people talking – especially when you tell them how it works.
