Something we’ve decided to use rather than candles: AA battery-powered wax candles.
We live in an area with violent earthquakes and an open flame is dangerous. We use these LED-lit candles once the sun goes down.
We’re now looking into solar panel-charged battery systems as a way to keep from buying batteries. So far I haven’t been able to find batteries that will hold a charge longer than four hours.
The candles themselves are expensive but we really like them. They do not contribute to the ambient heat during summer but still provide the illusion of warmth at night during winter.
I have them also. I use them in my bedroom with the tv on. It doesn’t light the room but is nice to have one at the tv and back wall.
Original batteries after 3 years.
It even has a waxy feel to it.
