Is this what you wanted?
Gail, are you talking about the white globes sometimes seen on a ceiling or bath fixture that have bulbs inside that illuminate electrically? If so, i would recommend filling them about 1/3 of the way with light colored sand, then shaking it gently while holding the opening up towards the ceiling. The sand should settle so it stays that way when you put it down. Now set a tea light inside and ...Voila'
I repurposed a couple of light globes from an old fixture into tea light candle holders for Christmas https://www.homeroad.net/2018/12/easy-repurposed-globe-christmas-trees.html
If they have a hole on each end, just place them over the candles!
