3W 3535 style 365nm UV LED on 20mm star PCB

These are made by LG. Unlike most power LEDs, these have inbuilt domes that produce a 60 degree beam angle, so they are more directional than most power devices.

They are mounted on a standard 20mm star PCB.

Use them like any power LED. Must be mounted on a heatsink!

Note that these have quite a bit of visible emission and produce a lot of UV light.

These are a high output UV LED, looking directly at them for any amount of time may result in eye damage!
