These LEDs are unique in that they emit UV light, which is great for projects requiring fluorescence (making glow-in-the-dark objects glow). They emit light in the 400nm wavelength (UVA).
We sell the following variants:
- 3mm with a flat top
- 5mm with a round top
Despite these LEDs operating in UVA, we do not recommend exposing yourself to UV for long durations.
