You touch one object that is no larger than 10 feet in any dimension. Until the spell ends, the object sheds blacklight in a 20-foot radius sphere for the duration. The blacklight spreads around corners. Nonmagical light can't illuminate it, and nonmagical darkness can't obscure it. Completely covering the source of the blacklight with an opaque object, such as a bowl or a helm, blocks the blacklight.

For the duration, invisible creatures, objects, and the Ethereal Plane become visible within this 20-foot sphere. Ethereal creatures and objects appear ghostly and translucent.

If any of this spell's area overlaps with an area of light or darkness created by a spell of 2nd level or lower, the spell that created these effects is dispelled.
