The Concave Cylindrical 5mm (T1-3/4) Discrete LEDs from LEDtronics® , the manufacturer and designer of LED products such as panel mount LEDs and PCB LEDs, emit light that is as bright at its edges as it is in the center. Concave lenses improve the quality of the light beam by spreading out the collimated beam of light that LEDs typically emit. These high-intensity LEDs produce illumination that is bright even in direct sunlight, and are therefore marketable for backlighting and channel-letter illumination. Sturdy leads are provided for wire wrap applications. There is a selection of six sunlight-visible colors: Green (525nm and 568nm), Cool White (8,000K), Blue (461nm), Yellow (596nm and 585nm), Red (655nm, 660nm, 630nm), and Orange (606nm).
Solid-state design renders LEDs impervious to electrical and mechanical shock, vibration, frequent switching and evironmental extremes. With an average life span of 11 years, LEDs operate reliably year after year and are appropriate for many applications. They can be used as indvidual pixes in a large dot matrix screen, full color screens, moving signs and displays.
