This is a Hensel Quartz Gold Flash Tube for the EH Pro 3000 flash head. It warms the light slightly, compared to a neutral, or white flashtube. Most current, professional flash heads and monolights are equipped with user replaceable flashtubes that may simply be plugged into, and unplugged from their sockets. With proper handling, these flashtubes may last for tens of thousands of flashes under normal use.
