I urge you to try whatever tea candles you get well before you need to depend on them. I have found some that do not burn well at all. Once the top part of the wick burns down, the candles would not stay lit at all.

Actually, for my money, the regular sized UCO candle lanterns are fine, and work well IMHO. There's not that much difference in the size, and there's less fussing around.
