With this system, the wax finish tasks, I use those little battery candles to light my party tables.
Batteries are supplied, there is more to move the switch and go for long hours of approval.
To change the batteries, is simple, they are CR2032 found in quantity and low price on Amazon.
After 3 evenings where I lit for 2 hours, not weakening, long may it last.
Finally, although these systems simulate the candles because there is a "flickering" and provides an aspect "flame".
Very friendly, and on top prevents children from burning themselves or set fire to the house.
Never a party without these candles.
