This is an ambient light. Most of the christians usually say grace before they will have a meal. The light can detect the prayers, and after the christians finish praying, the light will be on automatically and the food will look good under the light of the ambient light. The light which is given off from the ambient light can be seen as a reward for prayer. As long as we are grateful, the world will light up for us.
