Unlike other LED candles here varies of irregular flicker light and flowing up and down. As in Candle flames, which are moved by airflow. Other candles are more reminiscent of a loose connection. The pity is that the One flicker only on the remote control on and off. Here a 3-position switch would be appropriate. The power consumption is moderate. The candles are operated at me with commercial low-cost batteries. Not only have the concerns over an open fire in the apartment for all, these white candles are highly recommended.
