Colour of a gas mantle burner?
Another one of those questions that... nowhere else has the answer to.... can locostbuilders help...
Imagine an old style gas street lamp, burning the gas in a mantle style burner...
Anyone care to estimate what the colour of the light is on the chromacity scale in X,Y?...
Or in any other scale?....
And... what intensity in flux/lumens do we think it is?

Well judging by the one I used on my Tilly Lamp when I used to beach fish, on the 'chuffin bright' scale it's waaay up there!
Not sure if that's a technical term but there you go.
OK, I'm off now....

I can see the Locost attraction but I don't think they will pass the IVA.
Tell them about the bent treacle edges!

Probably entirely useless thread as I've no idea if 'colemans gas mantle burners' are remotely equivalent to what you need:

The jist of it regarding lumens:
quote:
Two mantle Coleman Gas lanterns are "about" 800 lumens, Two Mantle standard Coleman Propane lanterns are "around" 1000 lumens.
The Coleman Pinacle Propane Lantern is just shy of 1600 lumens, the last time we had them tested earlier this year.

Quick search shows that most mantles give light at about 2300°K which is about X=0.5, Y=0.4.
