Cylinder-shaped LEDs offered under L542 series have a circular 5 mm enclosure and flat lens.
To avoid wrong LED connection, a anode has a longer lead than the cathode.
All L542 LEDs have the scattering angle of 90 degrees and the current consumption of 20 mA.
The light output of these LEDs varies from 80 mcd for ultra violet LEDs to 2,500 mcd for white LEDs.
