After a friend's B&B was damaged badly by a fire started by an unattended candle in a guests room, I decided to remove candles from all non public rooms for the safely of everyone at my inn. I went to other innkeepers and inquired about the best kind of electric candles and where to buy them.
I got lots of advice. I decided against the re-chargeables since I could buy and recharge my own batteries for the candles. I also decided against the totally plastic candles because I love the look and feel of wax. Another thing I was warned about was that the candles that had the real looking wicks were a bad idea because people try and light them. (The fake wick is really a black wire that at a glance or in dim light looks just like a burnt wick.
I searched and searched on the internet and found lots of expensive battery operated candles. I was not satisfied so I went off to Costco and found several fine choices for a fraction of the costs I saw online. I decided on a $29.99 variety pack of 16 or so electric candles in different sizes, made of vanilla scented wax that have a large plastic flame that I was sure no one would ever try and light. To be sure I took all the matches and lighters out of the rooms and drawers that had been in here for the real candles that used to be there.
Everyone - innkeepers and guests alike - beware of the new electric candles. They look and smell real, but no wick means don't try and light them with matches. And don't buy the really expensive ones. I'm glad I didn't.
