Light sticks provide a power‑free light source by means of chemiluminescence

A light source that needs no electricity and no batteries is particularly advantageous when you’re on the move. Light sticks that work as glow sticks are therefore suitable for many outdoor activities.

A so-called glow stick is very easy to use

Light sticks are available in many different (neon) colors. They are very easy to use. The sticks are removed from the packaging and simply bent. At that moment they begin to glow, in the intended color. Their luminous power is weaker than that of a flashlight or light bulb. Nevertheless, they help with orientation in a completely dark environment. And last but not least, children take great delight in these practical lights. They glow for up to twelve hours and can then simply be disposed of in household waste. Glow sticks are recommended from about eight years of age.

Light sticks are available in different colours

The light sticks can be purchased individually in different colors. They are available, for example, in green, white, red, blue, purple and yellow. The brightness is the same regardless of the color. At ASMC, light sticks can also be purchased with batteries. These are not classic glow sticks, but the battery-powered light sticks are nevertheless a very good alternative to flashlights, as their lower brightness prevents glare. All light sticks can be used in various outdoor areas, such as camping, in the military and on hikes. The chemical glow sticks can be used independently of power sources. If the brightness is not sufficient, battery-powered models should be used instead. However, this requires taking along a sufficient number of batteries. The best solution is to use both variants so that you remain independent during outdoor activities.

Experten-Tipp:

Using light sticks as a light source while remaining concealed

There are lightstick models that emit their light only in the infrared range and can therefore only be located using night vision devices. This naturally makes you almost invisible, provided you are wearing night vision yourself and can thus use the light source. The human eye cannot perceive the wavelength of infrared radiation. ,

Questions: Light sticks

How does a glow stick work?

By bending the stick, a small tube inside is broken, allowing the previously separated chemicals to react with each other. The reaction is called peroxyoxalate chemiluminescence.

1 A plastic tube surrounds and protects the contents 2 Hydrogen peroxide in the glass vial 3 A phenyl oxalate and fluorescent dye solution 4 Hydrogen peroxide

What chemicals are glow sticks made of and how toxic are they?

Inside a plastic casing, two chemicals are mixed or brought into reaction by bending, which triggers a chemical process that releases light. Many sticks are specially filled with non-toxic ingredients, allowing them to be disposed of with household waste. In detail: most sticks contain hydrogen peroxide in a small glass vial that breaks when bent. The surrounding liquid is usually a phenyl oxalate (oxalic acid ester) and a fluorescent dye solution (fluorophore). Tests have shown that trichlorophenols and dinitrophenols also work well as oxalic acid esters.

How long do light sticks glow?

Depending on the model of the light stick, the burn time can be between 4 and 12 hours.

Another very common term, especially popular with children, is “Knicklichter”. From English comes the term “glow sticks”.

What special variants are available at ASMC?

We offer special sticks that don’t strictly fall into the glow stick category but work in a similar way. For example, McNett sticks with photoluminescent pigment technology can be easily charged during the day with normal daylight and then release their stored energy in the dark. There are also regular glow sticks in a mini version. They don’t cost much in a pack of 10 and take up correspondingly less space. We also stock the ever-popular party sticks, which are particularly long and thin and can be easily shaped. And finally, there are models that are battery-powered and can therefore be used again and again. These usually use LED technology because it is particularly energy-efficient.

What is the advantage of light sticks?

It is often stated that this faintly glowing light does not attract mosquitoes, which can be considered one of its greatest advantages. In addition, they are suitable for use underwater, which naturally opens up a wide range of possibilities. Otherwise, the colored lighting is usually just plain fun. At Christmas, for example, you can hang the sticks on the Christmas tree, avoiding the tiresome issue of candles and the associated fire hazard.
