high intensity energy efficient L.E.D light are the bookmarks of Lighting

A bookmark is a thin marker, commonly made of paper or card, used to keep the reader’s place in a book and to enable the reader to return to it with ease. Other frequently used materials for bookmarks are leather, metals like silver and brass, silk, wood and fabrics. Many bookmarks can be clipped on a page with the aid of a page-flap.

Modern bookmarks are available in a huge variety of materials in a multitude of designs and styles. Many are made of cardboard or heavy paper, but they are also constructed of leather, ribbon, fabric, felt, steel, wire, tin, beads, wood,
plastic, vinyl, silver, gold, and other precious metals, some decorated with gemstones.

Bookmarks were used throughout the medieval period, consisting usually of a small parchment strip attached to the edge of folio (or a piece of cord attached to headband). As the first printed books were quite rare and valuable, it was determined early on that something was needed to mark one’s place in a book without causing its pages any harm. Some of the earliest bookmarks were used at the end of the sixteenth century, and Queen Elizabeth I was one of the first to own one.
