About the bottle light. We use to make luminara out of a plumber’s candle some sand/dirt and a paper bag. I upgraded it for use outside the house here by using a pop bottle and cutting the top off ( it makes a good funnel ) and putting the candle and some sand in the bottom, I have a candle lamp that is junk it chocks with melted wax all the time. I think if I am going to use a candle lamp I will use one that uses tea lights.
