Thats another thing I never read on the internet. Thanks for the info GraphicGr8. Will include it in the article.
Yeah there's a lot of stuff you'll never read on the net. But the correct way to solder is on the net. Just google soldering wires.
Another thing is to watch the power of the gun or iron. Too much heat and you can burn up the led. I've never burned up components. (cough cough cough) I've got six or seven weller guns but my favorite is my little iron. Just right for delicate work.
Something else to note. Solder itself. Most of what you find is thick stuff. They also have (well, had anyway back when I bought it) solder that's almost hair thin. It's great for solid state parts. It takes less heat.
