Eilistraee's Moonfire

A creature or item of your choice in range become outlined in a white, silver, blue-white, or a soft green light. that creature or item then sheds dim light in a 10- foot radius. You can control its intensity at will, ranging from a faint glow to a clear, bright light —though not blinding, and not dangerous. You may also create a free-floating beacon of light that generally has the same intensity as moonlight. 

This spell and the darkness spell negate each other.

If cast to create a beacon, as a bonus action on your turn, you can move the light up to 40 feet to a new spot within range. The light winks out if it exceeds the spell's range.
