Went to Ikea yesterday. I had to have one of these cool lights (look in the children's department). They come in three colors/shapes: blue, red and green.
Spoka glows from a light emitting diode. It will run indefinitely when plugged in or 4-6 hours on the rechargeable battery.
The light has a sense of whimsy that you find in lots of Scandinavian design, especially items designed for children. It's fun, it's practical, it's safe (doesn't get warm and uses low voltage) and it's functional (it even comes with a carrying bag that closes with a cloth ribbon). Very cool!
