True Sunlight

A 40-foot-radius sphere of bright light spreads out from a point you choose within range and sheds dim light for an additional 40 feet. This light is sunlight 

If you chose a point on an object you are holding or one that isn't being worn or carried, the light shines from the object and moves with it. Completely covering the affected object with an opaque object, such as a bowl or a helm, blocks the light.

When a creature enters the bright light area for the first time on a turn or starts its turn there, it must succeed on a Constitution saving throw against your spell save DC or be blinded until the end of its next turn. Creature who have the Light Sensitivity, Sunlight Sensitivity, or Sun Sickness attribute automatically fails the save. You and any number of creatures you can see when you cast this spell can not  be affected by it.

If any of this spell's area overlaps with an area of darkness created by a spell of 5th level or lower, the spell that created the darkness is dispelled.

At higher levels: If you use a spell slot of 6th level, the duration is 8 hours. If you use a spell slot of 7th level, the duration is 24 hours. If you use a spell slot of 9th level, the spell lasts until it is dispelled.
