Ultimate LED box has about 1,000 LEDs and a coin battery to view any of them. You will find all colors, shapes and sizes. This amazing box of colorful LEDs contains one of the greatest varieties we have ever seen! It even contains some Infrared types. These types emit invisible but safe amounts of IR energy that are useful in remote control and other applications. A tremendous value, this box has a slide out re-closable drawer that is packed full of useful LEDs. All LEDs are brand new-first quality (not rejects). Some may have PC leads but most are full length leads. We don't count each box but when we were writing this up, our sample box had over 1,000 (you may get a little bit more or less). Size of box 5.5" x 4.5" x 1.9"
