Light sticks, commonly known as "glow sticks," produce light through chemiluminescence. These 6" premium-quality light sticks will emit light for 12 hours. They are foil wrapped and have a minimum 2 year shelf life.
These light sticks contain hydrogen peroxide in a glass vial that is inside a solution of phenyl oxalate ester. The vial of hydrogen peroxide breaks when you snap the light stick and mixes with the ester to produce a chemical reaction. This chemical reaction emits light. Dyes are used in the ester to produce different colors of light.
