The electric tea lights come with an inductive charging station (See product image here at Amazon.com), that there is no wiring on the Charging needed. Simply the candles in the silver charger set, press the load button and after 10 hours are all 6 tealights full loaded. With a load of them burn about 12 hours. The LED light is perhaps come a bit too yellow, but that's easy to get over. By tilting the tea light by 90 degrees you can switch it on and off. Then you can each candle in a supplied, satin glass (no art material !!!) set and the fun can begin. The flicker effect, to mimic a real candle is gone surprisingly well overall. The flicker is not uniform, but sometimes faster, sometimes slower, sometimes more and sometimes less. Thus, a real flame is quite well imitated. The tea lights give off a very pleasant light which is excellent for a mood lighting suited. The strength of the "flame" is not too weak designed; the strength of a real candle flame fairly comparable. One of the main advantages is that these candles do not form soot can set or the house on fire. One can safely burn during sleep leave. Overall I would recommend this tea lights fully. If, as described by a Vorrezensenten, the candle is lit just 2 hours, then it is either not been charged properly or defective. A candle must shine definitely 10 hours, and more in the charged state. My tealights do that in any case all.
