Descriptions
The 57-21series is available in soft orange, green,blue
and yellow. Due to the package design, the LED has
wide viewing angle and optimized light coupling by
inter reflector. This feature makes ideal for light pipe
application. The low current requirement makes this
device ideal for portable equipment or any other
application where power is at a premium.
