Kyouei Design have a number of ingenious yet simple ideas among their product range; the balloon lamp is one that really caught my eye. They’ve been on the market for a while, but time hasn't ravaged their ability to impress.

The lamp itself comes flat-packed and is merely made up from a standard balloon, a high-intensity, low energy LED bulb and a couple of lithium coin batteries. Once the the balloon is inflated you have a great temporary, wireless lighting solution that lasts for around 100 hours.
