A mysterious OD-2086 UV LED, like new condition, tested. In outward appearance these appear to be a metal can UV LED in the vein of the well known Nichia NSHU550 first generation UV LED, but in a gold enclosure with a flat glass lid. The internal construction appears more primitive as well; there is no reflector cup for the UV LED die, and the raised internal platform found in the NSHU550 is missing.
Note: these LEDs output a shorter wavelength of UV than commonly available 5mm epoxy LEDs, and as such they should NOT BE VIEWED WITH THE NAKED EYE! Looking at these LEDs while powered can cause permanent vision damage.
