Replacement of flashtubes for Elinchrom flash head models earlier than Style S involves loosening several screws on the flash head casing, and two screws at the flashtube socket base. Newer models have "plug and play" flashtubes that are easier to replace. With proper handling, these flashtubes may last for tens of thousands of flashes under normal use.
Some flashtubes are UV-Coated, or UV-Corrected. These tubes have a yellow appearance, and they counteract the excess blue 5700° or higher output of non-UV coated flashtubes. UV Coating lowers the color temperature to 5500°, which is the color of noon daylight on a clear day.
