The Led candles are placed in the non breakable containers and will last for 8 - 10 hours. You can have continuous light if you use 6 candles at a time recharging each half set. I use them on my hearth when the fire is not lit. In my bathroom at night instead of leaving a bright light on. You can even put them on window cills at night to scare burglars, All perfectly safe. I am sure there are many ways they can be used in the leisure business too? Theatre, restaurants, hairdressers, what else? Oh! Weddings of course!
