In Australia....[in the 40's & 50's?] the lamp we now call a Hurricane Lamp was just a Kero Lamp with a flat woven cotton wick that as it burnt down could be advanced by a small ratchet thumb & finger wheel
These were pretty simple & could be lit by a 10 year old under supervision by an elder......if you were in line of sight & a few feet away, they were pretty good at keeping the mozzies away, but did not produce too many Candle Power

Now the Tilly Lamp was a completely different kettle of fish

.......usually a stainless body with a throttling plunger to pressurize and then partially atomise Methylated Spirit again to a cotton wick which seemed never to burn down....and yes
Nemesis, that constant hissing sound

[not sure if these are now considered pressure vessels?]
These lamps produced so many extra bright Candle Power......that would illuminate the water in the bay where 100's of prawn catchers walked about in the shallows & trying to get one of the 50 or so prawns to jump into a net
So, there was also a clear distinction between the seasoned professional amateur prawn catcher as they placed their Tilly Lamps in small open hulled planked model boats....whereas the Saturday night amateur amateur would have a child holding the Hurricane Lamp just above the water and being constantly yelled at 'don't let the Lamp glass shell be splashed upon by the water'.....[or your life wasn't worth living]
So if it is a miniature Hurricane Lamp being considered.....just the faintest glow of light would be sufficient
