I thought that 10 hours were perhaps not sufficient, and I left a further 12 hours. But the blue LED on the charging tray died after 10 hours and the light stayed yellow, has not become whiter. As against the sparkling effect 'candle with trembling flame is amazing, very real! So these are ornamental lamps because it illuminates very little.
I find the white plastic tray reload truly hideous shame because the same Candle Lights are nice enough in their design and matt glass jars.
A star less so for the set and another for the charging time, otherwise they are lamps that give a nice effect, we already believes a little Christmas ...
