Radiance LED candles are made of 100% paraffin wax and poured into crystal-clear glass vessels. The LED flame technology creates an incredibly realistic and subtle flicker that glows 250 hours per set of AA batteries. Set the convenient 6-hour reoccurring timer or operate via the optional remote control, sold separately. This oversized pillar is perfect as a stand-alone or grouped together in a stunning display. ***Please note: Our Candles are made of real wax and they are temperature sensitive.
