Where did you find this info? I can't seem to find a definitive source for the heat output of a typical candle, but 300W for a single candle seems way, way too high. I doubt that a regular candle puts out even 100W of heat from the feel of it versus a 100W incandescent bulb.
Also consider safety. According to nfpa.org (2005-2009): "Candles caused 3% of the reported home fires, 5% of home fire deaths, 8% of home fire injuries, and 7% of direct property damage during this period. On average, 35 home candle fires were reported per day."
