This little gem is a nightstand favorite. No need to light for a soothing nightlight while the aroma carries you off to dreamland. Perfect for bathrooms & kitchens, as well.

Medium
This is the original style I used when creating, failing, experimenting, testing & for the eureka moment!  I tested dozens of different sizes, shapes, and styles of containers to achieve the brightest luminescence possible. These 2.5" x 2.5"-2.5" opening were superior to all others. Able to light a medium-large (or open floor plan) space.
