Laser Lights???

[Sam]

I have seen these around for between 30 to 40 bucks and wanted to know if
any one has tried them. If they do every thing that they say they do they
would be worth the money.
if you have not seen this yet here is a link to one I found.

I too have seem them, at a PetCo in Northern Virginia.

The box claims they are safe for fish, will not harm their sight, and
actually claims to help improve the fishes colouring.

I'm highly dubious myself.

You can get them at Walmart for around $25.00 for the Kit and about
$8.00 for each additional light. The kit usually comes with 2 lights
included.

Note: The blue looks nice for a few weeks and then fades to the point
that it is almost invisible unless it is the only light lit in the
tank and the room is dark.

The green lights tend to stay bright for as long as I have had mine
(about 15 months).

The red lights only work for a short period of time as well.

I have not tried the orange color yet, since $8 is a bit much to try
out a bulb that may or may not stay lighted for any length of time.

Also note: the wires for these lights are VERY Thin. I had attempted
to wrap the wires around the center support secction in my tank, so
that I could place the bulbs in the front and aimed towards the back
(better lighting that way, more visible). Anyway, that worked just
fine, except that the next week when I went to remove the hood I cut
the wire by placing the hood back to harshly. These wires are soo
thin that I was not able to re-attach it since I couldn't get the
plastic off of the inner conducter so I could solder it back together.

DON'T pay $40 for the kit as it can be purchased much cheaper.

As for how they look... well, I don't really notice them during the
day, but at night, they add a 'dim' light to the tank that enables me
to watch my night-feeders at work. You know, those fish you bought
that promptly disappeared under a rock and you thought were now dead?
Cat fishes, or pl*cos' come to mind.

Study on Effects of Laser on Tropical Ornamental FishStudy on Effects of
Laser on Tropical Ornamental Fish From The China Academy of Sciences 1998.

The results of many studies have proven that laser can increase the growth
of an organism, but it an also restrain its development. Depending on the
wavelength, power, and time of laser radiation, the results can vary because
of the conditions. The results of our experiments in the past few years have
proven that the incubation rate of eggs from map fish, five-colored immortal
fish, and immortal fish has all increased. Laser radiation on gold fish and
Mary fish can help their growth. Laser radiation on peacock fish and sword
tail fish can increase their colors while the quality of gold fish take on
variation after radiation. Our experiments also proven that fish and eggs
that have receive laser radiation have increased their disease resistance
and experienced lower mortality. 1. Increase in Incubation Rate of Eggs We
took the eggs from the same litter by the same parent fish and divided them
into two groups for a comparison experiment: a laser group and its
comparison group. The experiment is on the effects of different power during
the same radiation period and the effects of different radiation periods
under the same power. The results proved that, under the best radiation
power and conditions, the incubation rate for the eggs in the laser group
has increased 20% higher than the other group. The experiments during the
periods of cell division and nerve embryo have shown even more obvious
results: not only has the incubation rate increased, but the fry are much
stronger. 2. Increase in the Growth of the Fry We conducted experiments by
dividing into groups with the same radiation periods but different power,
under the same power according to different power, and under the same power
but different radiation periods. The radiation was on the fish one by one
and then on the fish and water together with the fish segregated in a small
area. Under the best power and radiation time, the fry with laser radiation
increased their growth speed by 30-40%, some even 104%, more than twice
faster. They could also breed ahead of time. 3. Effects of Laser Radiation
on Raising Fish We conducted experiments on peacock fish from the same
litter and divided them into laser radiation group and its comparison group.
The results proved that the female fish, after laser radiation, not only
increased their growth but also prevented the deterioration of colors. Our
experiments with gold fish from the same litter by dividing them into laser
group and its comparison group proved that the tail fins of gold fish, after
laser radiation, became long and big with bright and beautiful colors.
Therefore, laser can be used to increase the colors of ornamental fish and
create variation, enhancing the sense of beauty in ornamental fish. 4.
Effects of Laser Radiation on Raising Fish Because laser has good focusing,
high brightness, and good monochromaticity, the water used for raising fish,
after receiving radiation, demonstrated effective disinfection. The fish
raised in such water have strong disease resistance and lower mortality.

This all sounds great, but they don't give any real details. IE: what
power laser, what color laser, and how long duration of light and
intensity

It sounds like lasers are the answer for a lot of potential problems,
but I bet that these scientists used laser lights that are not
available now, and are unlikely to be available in the near future to
the hobbyist.

I think that the 'laser' lights the original poster was inquiring
about are not truely lasers. At least, they are not 'focused' lasers
and their intensity is VERY low.

However, for 'ornamental' purposes, they are good, at least the green
'laser' is bright enough to actually see in a tank, even with the
normal output florescent hood is turned on. Problem of course is that
green light does not a pretty fish make... The blues look good for a
short period of time, as in about 3 - 4 weeks, then fade.. same with
the red.

I took a good look at them when I was at PetCo. They appear to be a
"laser-pointer" style key-chain laser device, and from the one tank
setup with a demo, the intensity was very low indeed.

These are just led lights behind small lenses. laser light is not visible
till it bounces off something. Get a laser pointer and try it out in your
tank. For a cool effect bounce the beam off the surface of the water close
to where it is turbulent, so it shines on the wall off the water. It will
look like fire dancing on the wall. Have fun :)

Wouldn't this be unsafe for fish? Especially when it comes to their vision?
Last time I played with a laser pointer it had a warning about not shining
it into peoples eyes. If you shone it into a tank and a fish swam into the
beam, it's reasonable to conclude that it could cause damage.

I agree with that. I was making the point that the aquarium "so called
laser lights" were not really lasers.
The pointer I mentioned was for them to see the difference and with it you
are there and in control of it, as to not shine it into a fish's eye. It
would also be usefull to tell just how cloudy your tank is by shining it end
to end and seeing how well you can see the beam through the water, (
carefull to not hit your fish with it ). Fish also chase the beam on the
rock bottom like a cat would, proving they see colors ( since laser is
monochromic ).
