Candles are expensive, can leave a sooty film on furniture, and must be closely monitored because of the open flame. You can still get the scent and the soft glow from a wax warmer. It's simply a warm light bulb glowing beneath a vented ornamental dish. The wax sits above it and melts to a warm, but not dangerously hot puddle. They are available in many craft stores or through "Scentsy" a home sales catalog.
