The Mathmos online store offers a variety of different lighting solutions, mostly for moods and such. They do offer the Fireflow, which is a tea-candle powered lava lamp. That's pretty amazing. These lamps will glow for about 3 hours with the candle, which is pretty impressive. The lamps they offer are available in a variety of fluorescent colors, including some with glitter colors. If you like the Fireflow, you can pre-order it. It will ship in the fall. The Fireflow R1 will sell for £29 ($49 USD), and the Fireflow O1 is priced at £35 ($60 USD).
They've also got a bunch of outdoor lighting solutions. The Aduki light comes in different varieties and is charged up like a cell phone. It can then be placed outside. It lasts between 6-8 hours on a charge and is splash-proof. We really like these lighting solutions. Sure, they don't beat a DIY-Sun Jar, but still, they are quite fun to have around.
