Talk:Glow stick

message: The article mentions a shift in emission spectrum over time and refers to the following:
Spectral shift with time
Prior to this investigation, it was thought that the
chemsticks had fairly stable spectral distributions.
However, spectral distribution measurements of fourteen
lightsticks showed that there was a greater than expected
variance. In an effort to track down the source of this
variance, several lightsticks were measured at different
times after activation. Figure 3 shows the results of these
measurements. The spectral distribution of the lightstick
output shifts toward the red as a function of time after
activation.
However, looking over the internet for other sources to this claim I can find none. Can anyone confirm this and does anyone know why the shift happens?
PS. CPPO which is used in comercial glowsticks does not form phenol, it forms a phenol molecule with a chain of carbons attached to it which is conciderably less toxic. The hydrogen peroxide can however be an irritant.

message: Light stick and Glow stick. Both terms are used depending on the quality of the stick. The light stick in a dark room you can see objects around you for a longer period than a glow stick. The glow stick is not made for lighting it is more of a party or toy item, not as bright and cheaper to manufacture.
I have seen both. I have Cyalume "Safety Lightsticks" made by Omniglow. I understand both terms to be perfectly acceptable, wher I live, Edmonton, Canada.  —Preceding unsigned comment added by Magu2k (talk • contribs) 06:38, 16 February 2008 (UTC)

message: While this article is short, to the point, and very well written, the chemistry behind it is incredibly detailed. At first glance, it almost looks like something most readers wouldn't be able to understand. There are a lot of chemical names and a few conversions. The page is also littered with links to articles that don't exist (or need to exist). The first paragraph is good, but the rest is just mind-blowing. Much of this information can be labeled as "jargon", that is, information and terms that common readers probably do not understand without a field of expertise. Is it possible to describe the chemistry on more simplified terms? Colonel Marksman 15:47, 22 May 2006 (UTC)
replies: text: I've had a look at the chemistry section, and unfortunately it's already about as simple as it can be without making it trivial ("A chemical reaction happens and then it glows."). Ignore the specific chemical names, because they aren't secret chemistry jargon for something you know by another name, they're weird specialty chemicals you've never heard of before unless you work in the dye industry or something. (You probably have heard of hydrogen peroxide, but if so you already knew that, because in that case the chemical name and the common name are the same.) 68.105.71.75 (talk) 10:43, 29 April 2010 (UTC)

thread_title:  Electroluminescent lightstick 

message: Could someone include information about Luminol based sticks containing different chemicals?
(A spam-banned glowsticks website I can't post here) lists alternate ingredients not including Cyalume or anthracene which are not mentioned in this entry (unless I misunderstood a chemical formula). These ingredients included luminol, ammonium & sodium carbonate, and copper sulfate pentahydrate.  I'm curious as to how these sticks are different from cyalume sticks and how/if they're less toxic.  (I have a suspicion a lot of people probably find this article looking directly for qualified information on how non-toxic glowstuff really is or isn't.)

thread_title:  Luminol sticks & Toxicity 

message: In the "Usage" section of the article there is a line which reads:
When punctured, glowsticks can also be used as pens to write messages that can only be seen in the dark. This is not recommended as the chemicals in the sticks can be dangerous.
Then in the "Toxicity" section, it says:
Glow sticks are not toxic. They can however be mildly irritating to the skin.
So are they dangerous or not? --Candy-Panda 14:11, 31 March 2007 (UTC)

I haven't done any true testing, but I left one in the glove box of my car while it was -40 Celsius outside, the liquid still worked, but seemed to be a little thicker than normal. It breaked n shaked jsut fine and stayed lit well. I didn't measure teh actual temperature of teh stick though, so it may not have been -40c. Does anyone have any more specific information on the temperature range and variation? IE storing in a vehicle and taking it to extremely hot and cold places?  —Preceding unsigned comment added by Magu2k (talk • contribs) 06:41, 16 February 2008 (UTC)

thread_title: World's Biggest Glow Stick

message: The article contained an unsourced claim that freezing glow sticks will not work for more than a few days, and that after this time they would cease glowing entirely.
This is false. As a child, I routinely froze glow sticks and played with them weeks or months after the initial activation. One time, I left a glow stick in the freezer for an entire year: I cracked it on Halloween, and took it out again the next Halloween.  I remember being very impressed that it still had a significant (though diminished) glow left. I used the regular fat green glow sticks for this; I found that the thin bracelet-type glow sticks had a *much* shorter lifespan in the freezer.
I know this is original research, but I do not require a source to remove an unsourced (and clearly false) claim. Therefore, I have removed the relevant lines. 68.59.52.128 (talk) 17:24, 1 May 2010 (UTC)

message: There's one detail I would like to see added: what is the form of energy that is released by the chemical reaction that is responsible for triggering the dye? Currently, the article simply says: "energy" but not what form of energy. Is it UV or some other high-energy light? (This is how florescent dyes typically work.) Even if this "energy" is too complicated for this article, at least something that could point the reader to additional sources would be a great addition. 206.83.48.110 (talk) 07:50, 21 January 2012 (UTC)
