There are all identical candles, which can be operated with AA or AAA batteries and not continually generate hazardous waste! Since just come every few weeks back freshly charged batteries in and you do not have to keep buying new expensive umweldschädliche batteries. Some of them also have timers that turn then daily at a chosen time on and off. In any event, such LED candles are to operate economically, as they are an incredibly stupid cost trap.
