What is lume made of?

Lume, short for Luminous material, is a type of paint or pigment that glows in the dark. It is commonly used on watch dials, clock hands, and other items where visibility in low-light conditions is important.

Lume is typically made of a mixture of phosphorescent material, which absorbs light energy and then slowly releases it over time. The most common type of phosphorescent material used in lume is called Super-LumiNova, which is a non-radioactive substance that is safe for use in consumer products.

Lume can come in various colors, with the most common being white or green. Different brands and manufacturers may have their own proprietary formulas for lume, resulting in variations in brightness and longevity of the glow.

Overall, lume is a useful tool for enhancing visibility in low-light conditions and is a popular feature in many modern watches and other products.
