Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You haven't learned this reading yet, so here's a mnemonic to help you:
Who wanted the candle to be lit? Tom (とも) Cruise. He's afraid of the dark so he always wants all the lights and candles in the house to be burning at all times.
I can see light burning in that room.
