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 (comp. B on the diagram above). 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. Heating the glow
sticks (providing extra energy) will speed up the reaction, what will result in brighter
light but will shorten the glow time. The reaction will slow down in low temperatures
(the light will dim, but the glow time will be longer).

How to activate them?

To activate:
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 can not be turned off once activated

Does temperature affect the glow time?

Yes, it does. Higher temperatures will make glow stick glow brighter but will shorten the glow time.
Lower temperatures do the opposite. Changes of temperature between 15 - 28 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. Once the process of glowing comes to an end,
light stick should be disposed of.

Are they waterproof?

Yes, light sticks are waterproof and can be used underwater for night diving, surfing or pool parties.

How to store light sticks?

Chemical components of glow sticks are sensitive to light and humidity, therefore glow sticks should
be stored in original undamaged factory packaging. Prolonged exposure to light and humidity will
shorten glow time or can make glow sticks totally inactive.

What is the shelf life of light sticks?

Light sticks kept in original undamaged packaging have a shelf life of 0.5-2 years (depending on the type
of product and storage conditions).

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. Do not puncture or split open
