The 1P21 is a side-viewing photomultiplier designed for extremely low light applications. The tube has a lime glass envelope, a humidity-stable beige base, and outputs maximum amplification at 380 nanometers. This tube is capable of detecting single photons, and will be destroyed if powered up while exposed to ambient light.
