presents Concave Cylindrical 5mm (T1-3/4) Discrete LEDs emit light that is as bright at the edges as it is in the center, improving the quality of the beam by spreading out the collimated beam of light that LEDs typically emit. These high-intensity LEDs produce visible illumination in direct sunlight and available in six sunlight-visible colors: Green (525nm and 568nm), Cool White (8000K), Blue (461nm), Yellow (596nm and 585nm), Red (655nm, 660nm and 630nm) and Orange (606nm).
