1W handheld $170 - 445nm diode $20

[jieff111]

------------------------------------------------------ Hi there, I´m interested in purchasing your 445nm. I´m a laser enthusiast since 8 years know and a reputable member of laserpointerforums.com. I´ve written laser reviews like this one --> http://laserpointerforums.com/f52/cni-1w-447nm-pgl-iii-c-53473.html#post750871 If you´re able to give me a half price discount on your 445nm unit, I would love to do a review like mine one above with a lil bit promotion. I have a laserpowermeter, spectrometer, would measure divergence, beam diameter etc. + taking some spectacular pics. If you´re interested, just write me.

 

[jieff111]

Thank you,

I really appreciate your step. Sorry for the late reply, I was on holidays.
I´m sure my REVIEW is going to boost your sells a lot!
I have to wait till the money transaction from my bank account to my PAYPAL account is done, but it is going to happen in about 2-3 days for sure.

If you have any questions or if you want me to add anything special to the review, just tell me and I´ll do my best to fullfill your wishes! Hope you can send me a good review unit with an output around 1W.

livylaser = cheap Chinese crap, plain and simple. Nothing on that laser is likely worth $170. You could build a better waterproof laser for a lot less that will actually hit 1W. You might as well just go that route since apparently it is perfectly fine to have to open a brand new laser and adjust it

Rayfoss waterproof host - $18 shipped
A140 diode - $42 shipped
Microboost - $26 shipped
Glass Aixiz - $12 shipped

Than $30-40 for a battery charger, batteries, and saftey glasses and you're only at $140ish.

I would avoid this lvilaser like the plauge, it's not worth it if you have to spend hours "fixing" a new laser to make it work right.

It is rather bad form to disclose others name and address in a post.
Reported.

 

[DJNY]

I told you that I WAS the one writing you, what´s the problem??

There is no secret that I wanted this laser. I rethink the whole case, but in the end you show us your bad customer "support" very well. The $85 for the review unit would be a fair deal, both sides would have benefited. As mentioned, I would have to spend a lot of time on such a review, also English isn´t my motherlanguage.

That you mentioned my name in the post before shows again that you give a f*** about your potentially customers.

I waited 2 hours while my batteries charged before I did a power test. I also used 2 seperate sets of batteries (I have over 70 CR123A right now) I would love to "adjust the current" but I see no potentiometer on the driver. Is there one? Has anyone else seen one? Should I start removing resistors? As for your tail switch. Nothing is wrong with the clicky. That is true the problem is the small cylindrical piece that goes right on top of it. It was machined a couple mm too short. If you replace these with a slightly longer one you won't have a problem. You're a very funny "foreigner" thanks for the laughs.

DJNY,
You made a very generous offer.
Paying a $85 discount for a review by someone qualified and respected here is a good deal for a new company.

Hi, foreign friend, there is no potentiometer, we have adjusted the current to around 1A, you don’t have to adjust it. This current design is good, it will not have any heating, and if the voltage is not enough, the blue will flash, it means the voltage is insufficient, it needs to be charged. Regarding the switch, you can loose it a little bit, you should not screw it tight.

you told him to adjust the current on post #216, and now you are saying there is no potentiometer on the laser driver to adjust the current :thinking:

I am that yobresal will not be used in foreign counties, because every 1w blue laesr pointer of us can at least guarantee the power is over 800mW-1100mW. As for blue laser tube, it is different from the laser of 532nm and 473nm, the power is uncertain. As it lighting power needs the combination between 808nm and crystal, the light power will not increased by increasing the current. However, 445nm,405nm,650nm single laser tube can reach the rated power by adjusting the current, so it is very easy to make these single tubes have lights, you just need to adjust the current. We can increase its power to 1200mW. Therefore, it may be your own reason for only having 600mW light, whether the battery has enough electricity? I have learned from a friend that the power is only 735 under insufficient battery, so I said my product meets the standard. For many things, you should check whether it is your own reason.

Here the user should just adjust the current.

I don’t understand some of the foreigners, but please correct your attitude first, we are talking about the principles of the optical wavelength 532nm, 650nm, 473nm.405.445nm. Since we are using the same Japan 445nm laser tube, it is very easy to make the hand-held laser with the laser tube, as long as the circuit is added, its power lies in the current. It is no problem if we do 1200mW, we just tune up the current, coupled with its heat dissipation. If it is what as you say, why we want to make 600mW with the same tube, I am not sick, I would waste no resources. Only adjusting the current, the power can be up. Why not do it, I do not know how some foreigners are thinking.

Again user should adjust current.

Regarding the switch, you can loose it a little bit, you should not screw it tight.

Now there is no potmeter to adjust, and that is a feature as a lower powered laser will not heat up as much.

I really don't hope your company is paying you for this kind of customer contact.

 

[jieff111]

So this is what I am going to say, why the rated power of Japan 445nm tube can reach 1200mW, we just increase the current, it can achieve the 1200mW, why not do it? Why not make every 445nm blue laser achieve 1200mW. Here is the reason, which is to protect the tube. Coupled with the heating of the shell, the collaboration between two, you can not do this, we have conducted many research and tests, the best collaboration is achieved. It not only needs to make the power in the rated range, but also ensure the collaboration of the body, finally we fix the whole current, it ensures the power 800-1100W, the heating of the body, the service life of the tube. You should consider many aspects. Not just tune up the current. Do u understand, my foreign friend

 

[jieff111]

It seems some foreigners are directed against us. My explanation is over, I will not reply to anyone. I don’t like here, thanks you. We still alive without you, but some laser sellers will die without you. Because they almost have no orders in China, but we take up the largest market share. Even I do not have foreign markets, I still got the domestic market.

 

[yobresal]

.......it ensures the power 800-1100W......

The power output of the laser you sent me does not exceed 600mW. Your drivers are mass produced. They are not individually soldered with seperate value resistors to adjust the current. There are slight variations between diode efficiency and actual current output of your drivers but this should only give you a 100mW swing in either direction at most. Let us assume I am on the bottom of that swing. It would then be a good assumption that 0 of your lasers will hit the 1 watt mark. Instead of trying to defend your product from scrutiny perhaps you should open your mind to what you are receiving. We are experts here and are providing you with valuable information as to how to better your sales/product. We want you to succeed. We want you to make great lasers at cheap cost. What have you learned so far?
1. Machine the small cylyindrical brass piece in the tail cap 1mm longer.
2. Use a box not a bag to ship the products or the glasses will break.
3. Re-design the driver to reach a regulated 1-1.2AMP output.
4. Use an insulating buffer (black circular foam) around the contact spring.
5. Use smaller o-rings
6. Buy compressed air and clean the metal shaving out of the threading.

These are all valuable tips that you should be happy to receive. We are not perfect. Neither are most lasers. Please do not get so upset with us here. We want to help you. I build lasers. I found out that I did not tighten the set screw enough on a couple of my lasers. I received a complaint and now I fixed the problem and apologized for the inconvenience. Please humble yourself. If you do not want to make your lasers better than please do leave. If you want to be better than stay and learn.

Also please stop referring to people as foreigners. We are a collective of members from all over the world. That would make this a global community. The only foreigners would be from another planet.

Why the power of other can be 742 Current Draw at batteries ------- 570mA
Power Output ---------------------- 742mW，without electricity, and yours is under 600 with electricity, why the glasses of other are not broken, and yours are broken, why the switch of others are good, and yours is broken. WHY?? I don’t want to say much. Thanks for your good intention, I hope you are doing this for our good, not saying rubbish.

 

[yobresal]

These are good questions. These are the things you should be asking yourself. Luckily for you I have already provided you with the answers in the post in which I was quoted. Perhaps now that you have the answers you will work toward the solutions.
1. Broken glasses:
A: plastic shipping bag with no bubble wrap or protection. (some glasses make the trip others do not)
2. Switch broken
A: It isn't broken. It is a flawed design. ALL others have same problem. There are work arounds however that we are all using.
3. Low Output power:
A: low current because of driver.

The only rubbish here is not being spoken by me or your other paying customers. It is being sent out.... by you. You have the choice as to whether or not that is acceptable to you. It would appear to me that you have already made that choice. If I were you I would quitly leave the forum before you start getting paypal disputes. Your attitude and business ethics are equally as poor as the quality of your product.

It sound to me like you are questioning the integrity of a highly trusted member of our community. It is unfortunate that you cant see that he is trying to help you. But you have come here representing a company and have stated you don't like this place and that you don't care if we buy your lasers. That is not the attitude of a company I or any member of this community would do business with. As I said when I neg reped you if you don't like this place or care if we buy your products then GTFO!!!.

Also if you plan to do any more non domestic business I would suggest getting a better translator or better yet an employee that speaks non domestic languages that can help you convey information in a more diplomatic way.
