That ALED1WNWS160PI is one of the world’s best LEDs available today with high efficiency and natural white color. Its lower thermal resistance allows inputting high electrical power without overheating the internal die, resulting in high luminous output: > 80 lumens. The Side Emitting LED has an hour glass shape above the LED chip which directs the majority of light from the LED out the side towards the reflector. This allows you to focus the light beam for specific applications. Your beam will depend on the shape and quality of your reflector with the Side Emitting LED.
