Excimer Lamp (or Excilamp), marked 425
Lampe à excimère
Excimer-Lampe

This lamp was found in a Philips closed-down laboratory in Eindhoven (Netherlands).

It is probably an experimental lamp.

An excimer lamp is a source of quasimonochromatic ultraviolet light, based on the formation of excited dimers (excimers), which spontaneously transiting from the excited state to the ground state result in the emission of UV-photons.
See Excimer lamp on Wikipedia.
