Yep, it's a tea light.

The confusing part is that the US video title said alcohol stove. But that's because the base does dual use as an alcohol stove:

So I was thinking, what would it take to make a lantern? After all, there are models to follow. A Coleman lantern and an Aladdin Lamp come to mind. Did a little research and found out the mantels they use are radioactive :o (Coleman stopped using Thorium in the 1990's but not everyone did. Also, old stock may be floating around).

Lantern mantles are even being used as a test bench for geiger counters ;) :

I have already gone through some testing (without glass globe) with two of the radioactive vintage before I found out :( . Glass globe blocks most of the bad emissions. Apparently the most hazard is during replacement removal/initial burn if you breathe dust/fumes or it touches skin and you later ingest it. Also, carrying them in a pocket is a bad idea. Now, should I toss the two 20 year old thorium based one's I still have? :?

I did some experimenting with the mantles and was able to produce enough light to read textfrom a distance of about three feet. The mantel was affixed inside of a stainles steel chimney that had a window cut out of it's side.(that's where the mantel was) A Starlyte burner was used beneath the chimney to provide the energy for the mantel to glow. It was nowhere near a lantern's amount of light but it worked and looked so cool. It was a stovies moment of triumph to see it glowing :D :D :D

Sounds like you had a successful test Zelph,

I placed a mantle over a stainless steel mesh sink strainer and placed that over a wick stove. The steel mesh prevented the mantle from going incandescent. I think the steel mesh sank too much heat. Then I carefully removed the mantle and managed to replant it over my copper wick stove with only the copper wick for support. That worked with moderate success, parts of the mantle glowed incandescent, but then gravity started pulling the mantle in on itself. Based on my tests and yours, I think an Alladin lamp style frame work would be appropriate, keeping the mantle suspended fully. Also an alcohol wick stove appears to provide heat to support a workable lamp.

I bet it was fun testing your theory :D

I'll see if I can find the mantle type that I used.. It's normally used on driveway entry lights of the gas type. It has a ceramic base. I'll post a Starlyte accessory tomorrow that will show the type of flame that was used to excite the mantle material. I have not come across the original tube with a window.
