UV LED lights typically require a forward voltage of 5-6 VDC to operate, which is higher than the voltage required for visible light LEDs.
While visible light LEDs operating at 350 mA or 700 mA often start emitting light with a forward voltage of around 3-4 VDC, the more energetic UV LEDs need the higher voltage range to function correctly. This difference is primarily due to the higher energy photons emitted by UV LEDs compared to visible light LEDs. The specific voltage requirement can also vary slightly depending on the manufacturer and the specific wavelength of UV light being emitted. Always consult the datasheet for the particular UV LED you are using to determine its precise operating voltage.
