operated marker light for under $20 and save the waste of money. Do yourself
and your environment a favor, avoid these things and get a marker light. As an
added benefit, many marker lights can be converted to a backup light in an
emergency (the Princeton Tec is a 2-AA cell light with a transluscent colored
plastic cone that fits over the flashlight part. Pull off the cone and you
have a nominal emergency light).

Unless they've changed since my chemistry days, it is a complex luminous
solution which, upon contact with an alkali, gives off light. The solution
is in the tube inside; the "jacket" contains a relatively strong alkali.
As for batteries not being "eco-friendly" either, true; but for the record I
use rechargeables. And lightsticks are more prone to be "tossed overboard"
than a dead battery.

Would anyone know what these light sticks are made of??
Also batteries are not eco-friendly.

Couldn't agree more, Jeff. These sticks are like the disposable diapers
of the underwater world. The fewer we see, the better. I own a
Mark-Lite from Princeton Tec, BTW, & by using rechargeable batteries I
avoid any muss & fuss about throwing batteries away. Sorry, guys, but
cyalume sticks are not the best thing to use for recreational scuba.

I'm not trying to argue here.... I actually don't know.... Why are
Cyalumes bad for the underwater realm? They're sealed, and (I think)
that the stuff inside isn't toxic. (Not like I'd want to drink it :) )
What's up?

Look at it this way, the more Nickel and Cadmium you keep in a
waterproof container (light) the less Nickel and Cadmium there
will at large to pollute our environment.
Now if people just would use the same technology to power their
gas guzzlers we would be getting somewhere.

Here's my $0.25, John:
These glow sticks probably were created for military use, as a
self-powered light source. Divers noticed that they could use these
things as extra lights on night dives (& instructors probably loved the
idea of keeping track of their students on these dives!). A few were
probably tied to some tanks during a night dive, & word spread.
Ultimately, they became almost "de rigeur" for the well-equiped night diver.
However, people started to notice that these things are one-use-only.
What happens to them after a dive? They get tossed in the garbage, or
more likely over the side of the boat. If Jeff is correct about his
analysis of the chemicals inside, & they do incorporate an alkali as a
major ingredient, then it would follow that these chemicals are harmful
to animals & plants underwater. A light source underwater might
attract predators, who may swallow & bite the sticks. Pop, the chemicals
are released, & the predator gets terminal indigestion. If only on
general principles, these sticks just pile up & never degrade. A
battery-powered light is a more sensible option, especially if you use
rechargeables (like I do).
Anyway, this has turned out to be $0.75 worth, so enough.

You know, I suspect that we are straining at gnats and swallowing
camels here. Compare the cost to the ecology of a cyalume vs. say,
flushing the head in the liveaboard, or eating a meal at your hotel.
What is the cost to the ecology of importing all of that food, flying
to the island, (or driving to the shore) desalinating your shower
water, disposing of the packaging for food, sanitary supplies,
cleaning materials, laundry soap, and all of the other things it takes
to make western tourists happy? For that matter, how about generating
the electricity to recharge the batteries? Or the fact that ni-cads
do wear out.
For that matter, as a safety thing, what is the relative failure rate
of one of the battery operated marker lights vs. the cyalume? I
expect that if the cyalume activates at all, it will glow for its
allotted time. But dive lights flood, bulbs burn out, if you don't
have a light at night you just might be hard to find if you end up
well away from the boat and unable to return, say, because of current.
Save them, bring them home, and toss them in the trash, or the
plastics recycling bin.

Here Here..... I agree, and I(for one) have found a way to dispose of the
light sticks. We have rather acid soil and I use the alkali (highly diluted)
to change the Ph of my front yard so the grass grows better and throw the
plastci tube in with the recycle bin.
I think that the row over these little things is much overshadowed by the
ecological cost of the average dive trip and I agree that the chem lites
either work or not, if they are gonna fail, they fail at first and don't wait
until you are 10 mins into the cave to short out and cook. Not only that
they are not, as sold, a toxic problem. They only become a problem
when someone pitches them off the boat with the sandwich wrappers and
milk catrons from lunch.
Just my humble opinion.....:

Hmm, maybe I'm missing the point here. I always thought that cyalumes were
preferred as a locator for night dives because they are more reliable than a
flashight. That is, they only way they can fail is if they fail to light in
the first place (in which case you get another one) or if the container is
somehow ruptured (and if that happens chances are you're in pretty deep doo-doo
already). Flashlights on the other hand are prone to all sorts of failure
modes. It seems to me that it is a lot safer using a cyalume as a locator
than a flashlight.

Dive shops and charter operators discovered that they could make profits
by not allowing people to do night dives without them, and selling them at
outlandishly high prices.

As a Dive Group Leader specializing in Cozumel, I require divers who travel with me to attach a green chemical light stick (Cyalume)
to their first stage yokes on every night dive. Dive masters/ Instructors use red light sticks, and the primary dive master attaches a
strobe to his ankle.
Why? Several reasons.
- All Cozumel Diving is, to a greater or lesser extent, drift diving, and it is quite easy for groups to get strung out along the
reef during the course of a dive particularly if there are several photographers. The cyalumes are reference points for the members of
the group and the leaders. Group leaders/Dive Masters are are easy to spot in case of problems, and it helps keep the group
together.
- In the event of a light failure (although we preach fresh batteries and secondary light sources) the affected diver has only
to reach around to his tank valve and jerk off the light stick, Sufficient light is then available to see gauges to make an ascent and
safety stop. The cyalume is a reference point for the pick-up boat if the lightless diver has become separated from his buddy.
- As all Cozumel divers know there are favorite reefs for night dives and they look like the fourth of July on busy nights.
Since all divers look alike, we put a couple of wraps of electrical tape on the barrels of our divers' light sticks light sticks The
resulting striped lights allow us to sort each other out when the occasional group merges occur.
All responsible divers are concerned about the ecological impact and general trash posed by carelessly discarded light sticks. We
stress in every pre dive briefing that the light sticks are to be retained and deposited in a trash recepticle when we get back to the
dock. This is reinforced when we are back on the boat after the dive. This is a part of diver responsibility that must be stressed
during open water training the same as other reef protection considerations.

I'd like to know _how_ this practise came into being.
