So I thought I would try an optic glass from John Moncreiff. I like the effect but it is difficult to light because the butterfly clip doesn't fit underneath. The scalloped edges diffuse the light a bit. It fills the room without being too blinding.
A longer burner would fit better. Not so easy to come by though. I bought a Taiwanese Bialaddin vaporiser which works a treat on my bowlfire. That guy 'Phil Captain' doesn't have replica 169 vaporiser. Size comparison between globes
If you are in need of a 7 inch Tilley Vaporizer check this listing out. 7inch vaporiser of tilley lamp, bialaddin,vapalux | eBay I use this one on my Tilley R1 heater and it works great.
Hi Jean, You are correct it is on the pricey side of things but it is serviceable whereas the Tilley and Bialaddin/Vapalux vaporizers aren't. If you are able to find some NOS vaporizers which were made in the UK then you will have a good vaporizer but if it comes from China it may work or it may not. The 7 inch vaporizers are getting hard to find. I'm sure you will come across a 7 inch sooner or later. There is another gent that makes Tilley vaporizers but his are more expensive then the one I listed above and his vaporizers are a copy of the original. Cheers, Norman
