Operation is simple:
- Screw Candle
- Battery purely
Screw the candle -
- All candles by remote control on and off - ready!
The operating range is ok. In a few meters from the turning on and off worked perfectly.
The light is of course not as "hot" as in a conventional bulb. But the "cool" LED typical proportion is under (therefore "only" 4 of 5 stars).
To burn time: Over the Christmas holidays, the candles burned for many hours each day. Nevertheless, we had to change batteries. I think that LEDs are reasonably efficient.
For a larger tree in the coming year, we will buy another 1-2 additional sets.
For those who have no desire for the annual cable clutter and with very very little reductions in the "light-heat" can live, which I can recommend these candles.
