Title: led type
Post by: gamefreak on June 10, 2007, 06:55:35 PM

im looking on ebay but i dont know what kind of LEDs i have now, i figure if i want the simpliest color sensing then i need the Leds to be the same, is a 5mm dome the same as a diffused?

or should i try to find a picture that looks the same?

the only way a dome effects the light is that it acts as a lens that changes the focus of the light beam, there is also rectangular leds and bargraphs and so on

hope that helps

difused have the blurry colored insides, while not difused are usually clear with a hint of the color.
