The Definitive Buying Guide for LED Light Bulbs

What I've noticed lately is there's a lack of information that can be found on the web about LED light bulbs. Now there's a ton of information online about LEDs in general, don't get me wrong. But when it comes to LED light bulbs specifically and what to look for when wanting to purchase them, the information is very sparse, and if it even IS available, it's usually in a very technical format where you practically need an engineering degree to decrypt what the figures mean.

Because of that, we've decided to create a guide of our own. It's a guide that explains :

• What LEDs are
• How they work
• Why they are better than compact fluorescents

and most importantly,

• What features you should be looking for when purchasing LED light bulbs

The Great Wall of China - The LED Version

Those crazy Chinese are at it again with another version of the Great Wall, at least from my perspective. I guess they're in it to win it when it comes to grand displays to impress the rest of the world. Maybe this time they're actually getting it right. This version is made up of LED's and dwarves anything I've seen lately. Probably not the biggest I've EVER seen, but then again, it also isn't an installation that uses half a million watts just for the sound system. No, this wall is so "great" because it is billed as a zero-energy fixture.

The LED wall contains solar panels that harvest the sun's rays during the day, and uses that energy to display a video light show at night. How completely perfect. It's like the true circle of life. In theory, you could build one of these in the middle of the desert, away from any and all civilization, and play large-than-life size movies off of it. Take that another step further and I would LOVE to play some old school Street Fighter II on a deserted island. Although GTA IV would definitely keep my attention for a little longer.

This is a one-off structure, so I don't think they're selling to the general public, but if you have to ask how much it would cost, you definitely can't afford it. The new green buzzword of 2008 is "zero energy". I'm already an adopter. I've had this solar-powered flashlight for years....
