A candle with wind force 8

For fire protection reasons, I have decided to use these candles. 18 pieces for the price are ok. One of them is faulty - which is also acceptable.
Is getting used to for the very strong flickering.
Flaring is simulated by short interruptions of light, thereby acting very hectic and unnatural. One thinks more like a loose connection than to a lifelike flickering.
For a romantic candle-lit dinner I would be definitely too restless, but since I take then probably better to real candles ...
