I picked up a few surface mount LEDs that I intend to use as lighing effects if they are both bright and diffuse enough. The site that I got them from was limited on data about them, and I was wondering what you guys thought about using them. Other than being incredibly small and hard to work with, I don't know much about them, at all.
Aside from the package, they're just like any other LED. If you at least have a part number or something like that, you can try finding a datasheet on the manufacturer's website.
Not sure though how you want to use them. I know that some people solder wires to them (or buy them that way) and use them on their model train stuff, but on a large model like armour or a weapon, small through-hole LEDs seem like the better option to me unless you really need a light this small.
