Minimalist LED Headlamp For Kids

This is a nice children’s headlamp for about $18. We like it because it uses three bright, energy-efficient LEDs. So the batteries will last hundreds of hours. It has three settings: high, low and flash. Available at Amazon. See also this similar headlamp from Amazon.

Chameleon Lamps from Philips

Hold something in front of these lamps, and the lamp shade will change to the color of the object. There’s a standard light bulb inside, surrounded by a ring of LEDs which project the color onto the shade. These lamps will be released sometime next year by Philips. We also featured Philips’ interactive bulbs in a previous post.
