Factors that Affect the Durability of Glow Sticks

Thursday, July 28th, 2011

Glow sticks are commonly used light sources in night party decorations, night camps and emergency situations. Since, they are the single use translucent tubes and are required to stay functioning till the need is fulfilled; the durability of the light emitted by them becomes an important consideration while using them. Also durability of a product speaks for its quality. Hence, in order to buy good quality ones, factors affecting the durability of the product should also be considered.

In case of glow sticks, the light is emitted through a chemical reaction and not due to any external energy sources. Hence, the durability is associated with various factors of the stick and chemical used. Here are few factors which affect the durability of a glow stick.

Quality and amount of the chemical: Glow sticks work on the phenomenon of chemiluminescence, which involves couple of chemical reactions between the chemicals present in the stick. Hence, the quality of the chemical used in glow sticks is the primary factor on which the lifetime and the brightness of the light depend. The better the quality of chemical, the brighter and longer the glow stick glows. So, it’s always better to buy them from a well-known store.

Color and size: Of the various colored glow sticks, colors like green and yellow last for longer time and are hence used for emergency purposes. These are also considered as brightest colors followed by pink and red. Colors like aqua, blue, white and orange glow for shorter time.

Size also influences the durability of the light emitted. The longer the glow stick, the higher is the amount of chemical present and the longer it glows. Though the size matters, quality of the chemical is more important in deciding the durability.

Age of the stick: The older the glow stick gets, the dimmer will be its glow. And the colors which are originally dim become dimmer if their shelf life is increased.

Environmental conditions: The temperature of the surroundings definitely affects the durability of the glow sticks. Heat makes the chemical reaction faster and hence increases the brightness of the light. However, the brighter it glows, the shorter will be its glowing time.

In contrast to above situation, colder climate decreases the speed of chemical reaction, thus making the glow stick glow dimmer. But the dimmer glow sticks last long. So, if you want your glow stick to give light for longer period, simply freeze it.

Recycled plastic: Many glow stick manufacturers use recycled plastic, as it is less expensive. Thus they increase their profits even by selling them at cheaper rates. But usage of recycled plastic affects the durability of a glow stick. They can easily break and crack, which result in the leakage of the chemical. So, high quality branded glow sticks are always recommended.

These are the factors which affect the durability of glow sticks. Opt for high quality glow sticks from reputed manufacturers as they will be durable.

Why are Glow Sticks Excellent Sources of Lighting for Outdoor Activities?

Sunday, June 5th, 2011

Camping, boating, sporting and other outdoor activities, especially in the dark are always full of fun and excitement. Candles, lanterns and flashlights are the primitive sources of light for such events as they are less efficient and involve risks. Replace them with glow sticks to make your outdoor activities more enjoyable and safer. Here are some features of glow sticks which make them the best sources of lighting for nighttime outdoor activities.

Easy to carry

Carrying the light sources is one of the most difficult things you will be doing while you are camping. You would definitely want to carry easy to handle light sources, unlike lanterns or flash lights, which are big and heavy. Glow sticks are the perfect choice for you as they are light in weight and portable. A standard 6 inch glow stick will weigh just around 1 ounce and will be as small as a candle in size. They make your backpack lighter.

Safe

Glow sticks use a chemical reaction to emit light. They are safer to use as the chemical reaction giving light does not produce heat and spark. So, there is no need to worry about fire accidents in your camping area. This avoids the risks of injuries and fire as in the case of using candles or lanterns. They are even non-toxic and you can allow your children to safely use glow sticks under your supervision.

No need to recharge batteries

You will be in constant fear of losing the charge in the batteries of your flashlight. You cannot expect to get power to recharge the batteries while you are camping. Glow sticks do not require power or batteries to give light. They are, therefore, much more beneficial than flashlights which need batteries to be recharged frequently.

Wind and water-proof

The wind and water-proof characteristic of glow sticks make them the perfect light sources in severe weather conditions. As they are water-proof, you can have fun with glow sticks at beach-side games. They are great lighting tools for scuba divers, helpful for marking and indicating underwater direction.

Available in different colors and sizes

Glow sticks are available in different sizes. They can be as small as 1.5 inches and as long as 15-22 inches. Pack different sized glow sticks in your bag when planning for an outdoor activity. For instance, you can use smaller mini glow sticks which are 1.5 inches in length for fishing or decorating your boat. However, larger ones can be helpful to illuminate your camping area or playground for night sports. Glow sticks add more fun as they are available in different colors including green, blue, pink, yellow, orange, red, white, purple, aqua etc. In addition to solid color glow sticks, bi-color and tri-color glow stick varieties are also available.

Inexpensive

Glow sticks are the cheapest and best lighting options for any outdoor activity. You can get a 6 inch glow stick for as low as $0.42. Purchasing glow sticks in bulk makes them much cheaper. You can also buy in smaller quantities depending on your requirement.

Longer shelf life

Purchase them in bulk to get additional savings. You need not worry about the glow sticks, which are left after camping. You can use them in your next camping trip. The shelf life of glow sticks is generally 1 to 4 years and depends on the storage conditions. It is good to store them in a cool, dark and dry place. Glow sticks with foil packaging will last for about 4 years and those without foil packaging will have a shelf life of about 1 year.

With these benefits, glow sticks are considered one of the best illuminating sources for nighttime and twilight outdoor activities. So the next time you are planning for an outdoor activity, make sure that you have enough glow sticks in your bag.

Light Sources You Should Have in an Emergency Preparedness Kit

Thursday, February 4th, 2010

In a blink of an eye nearly a quarter of a million lives were lost due to a destructive earthquake in Haiti. Closer to home, every year in America natural disasters ranging from fires, snowstorms, and the usual hurricane, pound the country. With all of the calamity in our midst a renewed awareness has developed surrounding emergency preparedness.

Are you prepared if you lose essentials like power, shelter, running water, sanitation, and the like?

The recent tragedy in Haiti, coupled with the massive hurricanes that have hit America’s SE coast, has emphasized the need for households to prepare themselves should disaster strike. More and more people are looking for information on various items such as emergency preparedness kits.

This article will highlight one aspect that you would include in a kit, and that is light.

You won’t notice your need to see until you lose your electricity. Now, it obvious nobody is inept enough to live in complete darkness if electricity was never available, but generally you don’t truly appreciate something until you lose it. Even 24 hours without power will force a household to find light sources for few at least a few hours, if not more depending on location.

The chances of you becoming stranded and having to wait for aid is higher in remote areas. Generally the government recommends having a kit that will keep you safe for 72 hours.

When you think of lights, and if you’re lucky enough to be stranded in a place above ground, then you’ll likely have sunlight to help your days. At night, however, you’ll require light sources that do not electricity.

There are a few suggestions you should consider when putting together emergency kits, some require power sources, others do not.

Take for example flashlights. The best source of light and the one that provides, on average, the most reliable source, is a flashlight. They vary in size and strength. The issues with flashlights, however, are twofold. On one hand you the life of a flashlight will vary depending on power source. Most flashlights will barely last an evening’s worth of light. That is, of course, dependent on whether they are battery powered or crank powered.

Battery powered flashlights may lose charge if kept unused for too long, and they tend to last the least. LEDs over filament bulbs will also impact longevity. LEDS will use less energy to shine as their filament counterparts. They provide more light for less energy.

Some LED flashlights are now crank powered which means they generate a charge through someone cranking a handle. The charge is saved then used when turned on. This will obviously extend the lifetime of your light source, however, it depends on whether you’ll have someone capable to continuously recharge the light source. If elderly or incapacitated individuals are relying on the kit, this may not be the option.

Another source of light that also doubles as a source of heat are candles. Candles are inexpensive, yet do not emit very much light. You will require multiple candles to light a room sufficiently to complete a task. In times of emergencies you may not require a full room with light, but even then candlelight is limited.

Another danger to candles is the fire risk. The potential of falling asleep or having the candle fall to the ground and start a fire is high. This doesn’t suggest candles are a bad alternative for light, but they must be used with caution. Candles typically also last much longer.

Exposed candles are also at the mercy of their elements. If the area you require light is damp, wet, or the candle wick itself is wet, then you’re without a light source. Also, being outside may present a wind problem and an inability to keep your candle alight.

Another source of light is a glow stick. Glow sticks range in brightness and longevity. Typically green colored glow sticks last he longest, some as long as 14 hours, whereas colors like orange and red last much less. There are a number of benefits to having large glow sticks as part of your emergency preparedness kit. For starters, the glow stick does not pose a fire hazard, and because it is a chemical reaction, their reliability to produce light is very high.

Not only do glow sticks emit a large amount of light (more than a candle, broad than a flashlight), but they are not susceptible to the elements other than extreme cold. You can use a glow stick in a damp location and even underwater if necessary. Cold weather will in fact extend the longevity of the glow as the chemical reaction will be slower (but slightly dimmer).

The only con of glow sticks are their inability to produce any heat that you might get from a candle.

One single green glow stick could last an entire evening and into the morning. Candles usually last a couple of hours, and flashlights generally less depending on the size of the candle. That one single glow stick will cost you around 1 dollar. That’s 3 dollars over 72 hours. Flashlights will expire without batteries and candles can burn out, plus you require an initial source like a match to get a candle working.

So what should you use in your 72 hour emergency preparedness kit? I would recommend all three. They all have their pros and cons and most families actually have all three kicking around the home. All are generally inexpensive to keep tucked away in a kit.

So prepare yourself for the ‘just in case scenario’. Who knows, you may never need to crack open your kit, but you’re going to be prepared with a sufficient and reliable source of light if you take the simple and inexpensive steps to acquire the right resources.

Can You Stop Glow Sticks Once Activated?

Thursday, May 22nd, 2008

Some customers have inquired if it is possible to stop a glow stick from activating once part of it has been cracked/activated. The short answer is no. Unless you want to snip off the ends that were cracked and have a safe way to plug the open ends–there is not way to stop a glow stick once it has been activated.

However, you can slow the chemical reaction by placing the glow stick in the freezer. If you have received dead glow products from the store then you should return them immediately for a refund.
