Another one completed and listed on the first page. I only got one done for now but I am planning several more within a week or so.

I would like to add my story too. One of my geens just died and I thought of how tough yours are...

Alright so I have had my 1.9w for almost 7 months now, and can't resist looking at it least once or every other week. Any ways I have got to know how it acts and pushed the duty cycle almost 4-5 mins sometimes and it does get uncomfortably hot. Its great to zap pesky bugs too.

Anyways aside from me over heating too often I was using it at night as a beacon to signal for my dog to start searching. (much cooler than a walki-talkie) anyways after all that, it was in my hand I did not realize a 7 ft drop to cement was below me. Well I fought reflexes and held all the way to the ground with my hands out, and it slapped the cement so hard I thought it was done for. NOPE clicked it and it still runs like a champ 3 weeks later. :bowdown:

GREAT JOB ON THESE!

Lol, sorry somehow I missed your post. Sounds like your laser has taken quite a beating but I am very happy to hear its still working great. Those aluminum hosts can sure take a serious beating. They do a good job of protecting whats inside that's for sure.

Careful with those overheats though, it might not show it right away but that can and will reduce the diode's total life. That being said these diodes have so many freaking hours of life that you might not even notice a difference anyway lol.

I'm Curious to see the damage to the host from that fall XD.

People always ask about waterproof laser and I'm sure its all about cleaning tanks but people don't realize how hard it is to make a true waterproof laser

How about a waterproof version?

Sorry, with this host it is not possible.

I assume like what LL said that people desire waterproof for use in marine tanks but its impractical. The host would have to quite different from how these are built and the build would also cost more. The laser would have to be sealed which is more dangerous with lithium cells. With the ease of using the laser outside the tank its just not practical. Also, if the intent is to actually use the laser in, say a lake or the ocean, such a thing would be very dangerous and not what I would condone. Too many things could go wrong and result in injury.

Actually I am aware of enough of the construction issues and is WHY I would even bother asking if anyone else is into this type of construction. Yes. This is for aquarium maintenance. The 445 nm e/w G2 lens unit I have is sometimes used several times a day. Focus to within a foot inside the aquarium gives very good results. Killing critters reflecting off a large dental-like mirror 18" into the tanks leaves something to be desired. It does work but takes much longer and both sets of batteries when they fully charged.

Active marine aquarium owners with large systems have enough invested in their systems that there is little room for screwing around. People with smaller systems, not so much. Now that I have several weeks experience with this handheld laser, I now consider it a start. Definitely not a final solution. Considering that this device is dangerous in its own right, alternatives solutions are less power but water proof in some way (fiber optic??) or more power and external.

I have not researched this at all of recent, but I had development experience long ago with fiber optics for local area networks. All about wavelength compatibility, but in my minds eye at the moment would be a wall plug in air cooled laser module with a fiber cable coming off. Close in focus, a couple of inches or so, should allow for lower power lasers to be used. I don't really need to write my name in card board a foot away ... just sayin'

It always cracks me up that with all the other ways to clean tanks people still insist lasers are the way to go. Lasers are and never were intended for tank cleaning. There are products designed to clean tanks yet people still want to use lasers. Not a good idea, IMO, no matter what anyone says.

You know what they say about opinions.

I am not in love with the laser method, but using ... a litany of possible solutions I have/used ... the laser I have is much simple. But needs improvement.

" Lasers are and never were intended for tank cleaning. " given this forum ... is laughable.

And when botox was being developed for war it was never intended to be willingly injected into peoples faces. Sometimes using a laser is a good idea.

Lasers + fish = good how? I know lasers are adapted and were never meant for what we use them for but I just cant see how lasers and fish tanks is ever a good idea. We don't use lasers without protecting our eyes so did someone come up with fish glasses and I just missed that memo?

Unless you are there, no amount of explanation will probably have your approval.

These aquarium systems are to *fish* tanks as these laser pointers are to cat toys.

This concept of what certain things are meant for is starting to stymie me. Before you write the words "... not/never meant for ...", ask yourself why you even have a laser pointer over 1mW.

Whoa guys, no need to argue about this. It isn't that big of a deal.

While I dislike the particular part about lasers and fish vision, the alternatives I have heard of can be far worse. Flooding the tank with caustic chemicals designed to kill off the pests is hardly any safer for the fish. Also, not everyone has unlimited funding to continually purchase a particular type of worm that eats them but is also a bit like candy to the fish in the tank and are quite pricey.

Anyway, while I see both sides I have to say that the use of lasers seems to win out. I know of people that have built small blue absorbing shields to hold directly around the area being worked on as to prevent as much exposure as possible. Others employ their family members to hold up dividers and blocks to keep the fish to another part of the tank. So, not everyone who does this does so without thinking about the fish's vision. I have also heard from people who employ no such precautions and after months of use their fish are eating and interacting the same as always with no apparent degradation of their vision. I do however think that employing safety precautions for the fish is a much better way to go.

I have seen waterproof lasers but from my experience most are not so much waterproof but rather water resistant. Most of the true waterproof ones I see are overpriced and lack power or have had quality sacrificed due to increased complexity (sometimes both).

If you are using mirrors to bounce the beam further than a foot (or two) you may benefit from a 3-Element lens because those have much improved divergence and will produce a smaller dot at further distances. The drawback is a 20% reduced output power so while they increase the density of power at a range, the beam has less power overall. This means they are only beneficial at the point where they can produce a dot that is more than 20% smaller at a given distance.

Hey guys, I'm adding in a sort of feeler here for 650nm 250-300mW and for 780nm 250-300mW lasers in these hosts. I would like to sell them for $99 each and as addon to an order of a 445nm for $75. The lasers can be in any of the same hosts as the 445s and will run on two 16340s. The laser will look identical in every way externally except that it will be 650nm or 780nm as opposed to 445nm.

EDIT: BTW, 650nm is a deep red and 780nm is infrared. The 650nm is the same color as a typical 5mW cat toy laser but significantly more powerful. The 780nm is almost invisible except for a slight deep red hue though it can be seen decently by most cameras and will show up as a light purple.
