Ok thank you so much. I have loved lasers ever since I have been 9 and seen my first red pointer. I am now 33 and am finally able to get into collecting different lasers. I have just started trying to learn as much as possible about the way they operate, the science behind them, the engineering, as well as how to properly build them myself. As you can imagine I still have a long way to go as there is a lot to learn.18350 is 18mm wide and 35.0mm long
18650 is 18mm wide and 65.0mm long
26650 is 26mm wide and 65.0mm long
14440 is 14mm wide and 44.0mm long
So two 16340 cells add up to 68mm long and two 18350 cells add up to 70mm long so as long as your tube will accept 18mm wide cells it will take two 18350 cells in place of two 16340 cells.
Yeah I havent really been able to use my first high power laser hardly at all yet because I don't have any glasses. I have a 3 watt 445nm striker saber from sanwu and I honestly was shocked at the power of it the first time I turned it on. I have never owned anything above 150 - 200 mW before so when I first turned on my 3 watt 445nm laser it actually frightened me and I knew right away that it is just stupid to even attempt to use it without eye protection. I'm trying to find a fairly good deal on glasses that will protect between 405nm and 680nm and around 5 watts because this is the range of wavelengths that I intend on collecting. I really have no use for lasers in the non visible spectrum unless I plan on buying a laser cnc cutter with a C02 laser
I plan on buying some in the next couple days and dont worry I have made it a point to not even use the lasers until I get some. When i get my 520 I'll probably go outside and point it in an empty area of the sky after making sure no planes are in the area and then put it away until I get some glasses.WHAT.........NO LASER SAFETY GLASSES ????????????????????
GEE WHIZ FELLA
You really need to protect your eyes, one tiny moment's mistake can mean a huge lifelong disability.
Many here who know buy these, they are good quality at an affordable price, you should get some right away. > https://www.survivallaserusa.com/Safety_Goggles/cat1667093_1527285.aspx
Exactly.I understand that we don't always wear them, like pointing a beam at a safe spot in order to observe the beam in the air, but familiarity breeds contempt and you will find yourself working with it on the desktop, setting up mirrors, experiments, displays or servicing/building and I always reach for my safety glasses first thing, it's amazing how easily a mistake can happen ( everyone makes mistakes ) and if you are wearing your safety glasses when it happens you will be glad you had them, if not...............
I understand this very well. I have no plan to even use any of my lasers until I can find a pair that will cover all the wavelengths and power outputs that I own.Exactly.
Xquantumtheory20 - Accidents with laser happen so fast they there is no possibility of making a correction to avoid one once an accident is in progress. Permanent ocular damage and/o blindness from a laser hit to the eye happens in less time than it takes for time for the human blink reflex to kick in of 0.25 seconds so not the kind of thing you can avoid like avoiding a car accident by being a good driver.
Good laser goggles are an absolute necessity if you value your vision.
Get and Eagle Pair they work well and are relatively low cost, all things considered See: https://www.survivallaserusa.com/Safety_Goggles/cat1667093_1527285.aspx
You may need several pairs one to cover each--there are no proper laser goggles or glasses that cover the whole visible spectrum/spectral range.I understand this very well. I have no plan to even use any of my lasers until I can find a pair that will cover all the wavelengths and power outputs that I own.
I finally got a pair that protect against the 405-445s I own very well. Now I just need to get a pair that will cover the 520s and 532s I own and i will be all setYou may need several pairs one to cover each--there are no proper laser goggles or glasses that cover the whole visible spectrum/spectral range.
Have a look at the Survival Laser Eagle Pair page --click on the link I gave you---that is pretty much as good as it gets.
Any laser glasses/goggles that claim wider coverage are are not the right kind for powerful hand held lasers---theu are designed for cosmetology, estheticians, and skin care specialists laser treatments and medical treatments/procedures--so called IPL glasses/goggles ( Intense Pulsed Light) goggles/glasses. They are cosmetic patient protective eye-wear goggles, suitable for Intense pulsed light: IPL, cosmetic laser procedures, led treatments, removing tattoos, teeth whitening, photo-facials and laser hair removal for example.
Don't confuse those with goggles/glasses for high output power hand held lasers .
With a 1 watt 520nm laser on the way, you need to get the right googles now. I have 2 Jetlaser PLE-ProI finally got a pair that protect against the 405-445s I own very well. Now I just need to get a pair that will cover the 520s and 532s I own and i will be all set
A plastic coffe can I can believe but not a metal one. And I have glasses now. I have a 3 watt 445nm striker saber from sanwu a 7 watt custom build from lifetime17 a 1 watt 520nm ple mini and a 500mw 405nm sanwu pocket series so I am well versed with the power these lasers put out the dangers of eye damage without glassesWith a 1 watt 520nm laser on the way, you need to get the right googles now. I have 2 Jetlaser PLE-Pro
520 nm lasers. One measures 995mw and the other is 1200mw++. They are dangerous to your vision
and a fire hazard too. Get proper protection before you energize the laser the first time!
I have drilled holes through folgers coffee cans with mine, and I accidentally burned a spot on the piano...
In about a second!
Be careful! If 18350 cells fit, orbtronic makes a good one. I use 26650's in my PLE Pro lasers. I started with
18650's but I wanted more capacity. My 3.4 watt + 465nm blue PLE-Pro seriously needs 26650 cells. It is a
beast. It burns stuff like mad! It draws plenty of current. I thought the 1200mw green was cool for burning
until I got the bigger power blue. It needs to be reiterated...class 4 lasers are instant blindness if you
make a mistake. Treat them like a loaded gun. Seriously. Class 4 is dangerous. I have burned holes in things
accidentally. Stupid mistake...but I am not blind. Survival Laser sells great goggles. I own 3 pairs.
The extra pair for green and blue lasers is so guests can visit the lab and see the monsters in action.
And I have a pair for reds too.
Get the goggles before you buy cells!!!
Folgers does not sell metal cans where I live. They are all plastic. The lid is easily defeated! Burning all the way through theA plastic coffe can I can believe but not a metal one.

Yeah my 7 watt NUBM44 build literally lit by bed frame on fire. It really dark hard wood and it smoked and then a pink plasma flame lit up and then an orange flame literally started crawling up the side of the headboard until I blew it out. Never seen that happened before. Usually the flame goes out when u shut the laser off.. not this time lolFolgers does not sell metal cans where I live. They are all plastic. The lid is easily defeated! Burning all the way through the
red plastic sides is more difficult. My 3.4w beast did it so fast other stuff in the background got drilled too! OOPS!
