This is a UV Coated Flash Tube for select Quantum Qflash heads. The flash tube is simply plugged into and unplugged from the socket of the T series flash head. With proper handling, the flash tube may last for tens of thousands of flashes under normal conditions.
The flash tube is UV-Coated. UV flash tubes have a yellow appearance, and they counteract the excess blue of 5700K or higher output when compared to a non-UV coated flash tube. UV coating lowers the color temperature to 5500K, which is the color of noon daylight on a clear day.
