Finding the right type of lights isn't always as straightforward as heading to the nearest hardware store or Ikea. You got to search for the right stuff. Mood lighting is also something good to integrate in your decor. It's easy to become tacky. Thankfully, some of the lights we found over at Mathmos are really nifty. They have some great outdoor lighting ideas, as well as a cool candle-powered lava lamp.
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.
