I bought these fire starter sticks to see if they would make a better flame than a candle. They did make a slightly larger flame than a candle, but they didn't burn very long (about 15 minutes).
I prefer a large number of candles if you need some standard light that lasts a few hours. I buy mine at the dollar store.
If you want an intense light that will last 15 minutes use a road flare. They are AWESOME!
If you need large flames for a short period of time, go for the lighter fluid. Sweet.
