- 1.8 mm Diffused-lens LEDs -- New!
When 3 mm just isn't small enough!
The round lens of these LEDs is 1.8 mm (0.071") in diameter, and the rectangular part is only 2.4 mm (.095") wide. That means that you can stack these tiny guys right next to each other with 0.1" spacing, for example on perfboard or solderless breadboards. Seriously bright.
One pack contains ten each of red, yellow and green LEDs.
