Pete,
This esteemed veteran had never heard of ultra-violet (which I assume we're talking about) in the RAF during WWII... UV rooms ? - new one on me !
Our cockpit "spot" lights (useless) were dull red, IIRC. (Could they have been infra-red ? - don't think the RAF had heard about that, either).
I remember that, in the MPN11 GCAs in the '60s, we had UV hand lights: if your shirt had been washed in "Daz" (?), your cuffs glowed a treat !
Always ready to oblige,
Danny.
