That’s quite clever, it’s like a mercury/tungsten lamp without a discharge tube Cool

I thought these lamps lit like a low pressure germicidal lamps G4SII and therefore was strongly surprised that the filament light very well.

So what are these? Some sort of tungsten lamp with an unconfined mercury discharge for UV emission or to raise the colour temperature? I've never seen one of these before tbh!

This is the old sunlamp made by GE in 1930th. I saw an article stored in OSA site but I have no access to it. Information about this class of lamps is well presented by James here: http://lamptech.co.uk/Spec%20Sheets/D%20MC%20GE%20S2.htm
