Ex Royal Navy (HMS Ark Royal) Industrial twin fluorescent lamp (Not sure about the widely used description “Explosion Proof” to describe this type of light, I suspect it is fire resistant and enclosed so as to avoid the risk of sparks triggering an explosion by igniting high flashpoint gases). A tough industrial looking fitting nevertheless.
