Here's a candle lantern idea I got years ago here on W-B.
First I have a floorless tent, a Black Diamond Megalight. It's wide and tall (just like me!). I'm careful but often light the interior with a candle, and it provides enough light to read or write by. This idea also works very well in shelters.
I turn over my cooking pot or my mug for a base and place it where it won't be easily bumped.. On it I place a scrap of aluminum foil, onto that the candle, a tealight. Over it I place a globe made simply out of a small water bottle with the top and bottom cut out. It's just a cylinder of plastic but it keeps drafts away from the flame. Another scrap of aluminum folded into a long "V" stood outside the globe makes a nice reflector.
As always be careful. Bumping the setup too hard will cause the globe to get too close to the flame and the lovely aroma of melting polyester will fill the tent.
You never turned around to see the frowns
On the jugglers and the clowns
When they all did tricks for you.
BTW to avoid the smoke and smell you get when you blow out the candle (if the design of the holder allows this) just wet your thumb and index finger (saliva will do) and put the flame out with them . Work quickly .

You can take the glass out of your candle lantern, chip out the largest part of the wax, then just run it with your dishes in the dishwasher. It will come out looking like new. Be sure to only use the 9 hour candles specifically made for the lantern, though, because the "look-alikes" sold out there don't burn at the proper rate and will make a gummed up mess out of your lantern.
