1 d a t a s h e e t : c l d - c t 9 9 4 . 0 0 0 smd leds are packaged in the industry-standard package. these leds have high-reliability performance and are designed to work under a wide range of environmental conditions. this high-reliability feature makes them ideally suited to be used under architectural lighting application conditions. their wide viewing angle makes these leds ideally suited for channel letter or architectural lighting applications. the fat-top emitting surface makes it easy for these leds to mate with light pipes. features ? size (mm): 3.2 x 2.7 ? color and typical dominant wavelength (nm): ? blue (470) ? green (527) ? luminous intensity (mcd) ? clm1b-bkw (280 - 710) ?
