How long does the diffuser run on one fill?

Pursonic rates mist dispersal at up to 7 hours, which applies to intermittent misting. Running a steady stream will empty the tank faster.

Does it come with essential oils?

The listing says it contains essential oils, but no refill is included. Plan to buy oils separately if you want to keep using it.

They are separate functions on one unit, so you can use the sunset projector light without misting and run the diffuser with or without the LEDs.

It measures 8 inches deep, 8 inches high and 8 inches wide, so it fits on a nightstand or desk but takes real space.

The sunset projector lamp is USB powered. Use a standard USB adapter; a weak adapter can dim the light.
