What makes them work?
Light is generated by a chemical reaction called “chemiluminescence". Typical glow sticks as chemical reactants use: a hydrogen peroxide solution (which is called the "activator") a solution of phenyl oxalate ester and a fluorescent dye (which makes the colour). The activator is stored in a thin glass capsule. When the glass capsule is broken (by flexing a glow stick) the activator is released, and mixing the components (shaking the glow stick) initiates the reaction. Depending on components used, the chemical reaction can last (glow sticks can glow) from a few minutes to many hours.
How to activate them?
Bend (to break the internal glass capsule) & Shake (until it glows evenly) do not bend activated glow sticks any more; excessive bending may break the plastic tube what will result in leakage
How long do they last?
The glow sticks we supply will glow 6 to 12 hours, depending on size, colour and type.
How to turn them off?
They cannot be turned off once activated
Does temperature affect the glow time?
Yes, it does. Higher temperatures will make the glow stick glow brighter but will shorten the glow time. Lower temperatures do the opposite. Changes of temperature between 15 – 28 deg do not produce substantial changes in glow time.
Can they be re-charged after they stop glowing?
No, there is no way of re-charging or re-activating.
Are they waterproof?
Yes, light sticks are waterproof and can be used underwater for night diving, surfing or pool parties.
What is the shelf life of light sticks?
Stored correctly in a dark dry container (box they came in) glow sticks can last 2-4 years. Prolonged exposure to light and humidity though will shorten glow time or can make glow sticks inactive.
Are they safe?
The liquid light source is non-toxic, no heat or harmful radiation is produced.
Please note that the activated liquid even though non-toxic may contain tiny shards of glass which may cause injury should the light stick be punctured or split open. The liquid can permanently stain clothing or furniture and can cause skin or eye irritation. Some light stick products may contain small elements, posing choking hazards.
Light sticks are not suitable for children under 5 years of age without adult supervision.
Do not puncture or split open
Here's a trick - even 'dead' glow sticks will continue to shine if they are placed under a black light (UV)!
