PointLight

A bulb. Light spreads in every direction from a part or a null: lamps, candles, glowing props.

A PointLight shines in every direction from the centre of the Part or NullObject it sits directly under, out to its Range (8 by default), at its Brightness and Color. In Rendered it is path traced with soft shadows, and the part it sits in doesn't block it. Insert > Light > Lamp makes a warm one with Range 20.
