lighting is the
way to go. Wall
sconces are ideal for this.
ADA Compliant

American with
Disabilities Act.
Alabaster
A term used to describe semi-opaque glass that diffuses the light source
without altering
its color. The glass gets its name because of its resemblance to natural alabaster.

enough
visibility to do tasks such as cook, clean, get ready, or work.
