You really don't know what you're going to get with the no name cells and with the Ultrafire or xxxxFire cells. In my particular case, I have 4 no-name cells that outperform the 4 particular Ultrafires that I have. Not to say that any particular cell will always outperform another. As has been proven on CPF, some of the Chinese xxxFire cells from one batch will be very good performers. The same part number, same wrapper etc. ordered 2 weeks later could be a lame batch. (CPF has tons of good 18650 comparisons btw)

The cheapest way to get them is just to order a few from DX and wait. If you just pick something that has a huge number of positive reviews, chances are you're going to get good cells. Free shipping and cheap price. :) Even if you get some that aren't the best performers, it won't matter since most of our lasers are not very current hungry anyway. The performance of the cell matters a lot in high current draw flashlights but not so much in these relatively low draw lasers.

What I like to suggest (if you enjoy tinkering with electronics) is just ask everybody you know if they have any old laptop batteries that they aren't using. You will most likely find some, and inside of each pack will most likely be some good cells waiting to be harvested. It's kinda interesting if you have the time to waste taking them apart and testing the cells.

EDIT: I am very sorry OP to hijack the hell out of your thread. :( I hope that your battery and charger comes in soon, and I look forward to hearing about the performance of your new laser!

Not a problem. Learned a few things. When and if I get the battery Monday I'll let you guys know. Once played with for awhile I'll post on the forums a review.

Ok thanks. I've ordered 8 of the Ultrafires, 7 of which worked. DX replaced the other one. I might check out CPF, but I really can't stand the forum and I left a while ago... Plus it seems like they don't recommend anything but AW's. Also, doesn't the light control the current flow, with it's driver? I would think if a light is regulated, it could pull as much from the battery as it wants to.

Well, I'll post a review later, but i did get them today (didnt test yet) I just wanted to shout out some answers i got from an email.

1. The laser does have protection, so you cant put one in backwards and kill it
2. The charger is a smart charger, it automatically will fully STOP charging when full charge.

What should i really put in a review? Do people usually do beam shots and stuff? Will say so far im loving it..My room has natural sunlight and all 8 lights on (CFLS) and I can see the beam faded...I compared to my 10mw green, which you cant even see 50ft outside, this shines as bright as my 10mw at night, outside in the day. :) Loving it :D

A review would be great. Just put in a lot of information about the different parts of the laser, with pictures throughout. And yeah, people love beamshots.

What specs did you get for it? And how does it burn?

yeah i can do specs and all.. i cant do a true power mW test sadly. I havnt got much to messsing with burning yet, I got my bluray module from someone on the forums today also! So I put my flex drive to use, I got a 2AA maglite, hacked it out, and now i got a 2AA maglite bluray laser :D The only bads about this one is no heatsink. sticks out 1cm almost. I may leave it as is, I'm fine with 60 sec duty lasers..i dont NEED it to be a constant...So i think it will be fine running it as is.

As far as burning, I have so far done plastic etching as my first fun test :p I'll post a thread tomorrow.

What's the blu-ray diode? You could probably super glue washers together, and fix the module in the middle (that's what I do).

I only know its a PHR diode running at 120mA inside a focusable Axiz module, which i got from daguin. I can do washers..But dont you have to have a prity good tight fit on the module to transfer heat? I do have tons of heatsink paste...When you need to apply paste to IGBT bricks, you learn you need to stock a lot of grease.

I'd like to get beam pics before making my review...Can someone give me tips? I set my camera to manual but im having issues capturing the beam...in a dark room its really hard to see. To the human eye, its solid bright. To the cam, it was very faded..So can someone give me some settings? ISO? F-Stop? Shutterspeed time...etc

For the beam pics change your shutter speed on your camera so there is longer exposure and you can also change your ISO settings and see which setting works best.

My Aixiz module fits perfectly in the washers, probably about 1/2mm of space if that. I just glue 4 washers together, and the Aixiz head inside of that. I'll post pictures if I can find them.

What camera setting are you using? Try to take the picture in as dark environment as you can, so that you can make the exposure higher without the background being to bright. If you are using SLR or manual settings, put the f/stop as low as it can go, the shutter speed as slow as it can get. The higher ISO you have, the brighter the picture will be, but you will get more grains. I wouldn't go past ISO 300, unless you have a good low-light SLR. If you are using automatic settings, put the exposure comp. as high as it can go (usually +2.0). These were both taken at midnight, and it was almost pitch black:


f/5.6, 13 sec, ISO-1600

IMG_4193.jpg


f/3.5, 30 sec, ISO-1600

IMG_4194.jpg


You can see what I meant about the grain...

Ya..It's harder to do such long times when your laser is a 60 sec duty. So the switch is momentary, not toggle. That being said, if you move it even a little, you'll have a blur :p Else I guess I can rubber band it...

True but my laser again is a 60sec duty...so i couldnt have it run toooo long...

About my blue pen mod....I decided id risk the cost of the flashlight..and really hack this up for a button and large heatsink...Was 12 dollars so, risky but too late I already started :D Will post it on a separate thread when i see progress.

By the way, I'm going to the park friday maybe (woods) for laser shots...

Think this random metal bushing i have will do for a PHR heatsink?

Picture 2 shows how close of a fit it is.. ill cut it to size to fit inside.

It depends on the material. If it's Aluminum, it looks pretty good. But it also looks a bit big for whatever you want to put it in. So you're buying another flashlight for it?

Plus, if there is a sticker saying <5mW, they will never test it. And likewise if the sticker indicates >5mW, it will immediately be confiscated. The funny thing is, my sticker said "<5mW Laser; Class IIIB". Apparently the FDA isn't too educated about lasers. :D

It probably depend also from the "honesty" of your custom officers .....

As example, here in Italy is prohibited to import anything from class 3 or over ..... few months ago, i had ordered 6 "gift type" pen pointers from HK (not o-like) that was clearly stated on the labels being LESS than 5mW and class 2B ..... after 143 days without notices nor communications, i got a mail from our custom office saying that they "sent back" to the seller the pens, cause they was "class 3 lasers" and the law prohibit the import of them ..... only insignificant detail, the seller never got any communication about that, nor, ofcourse, the lasers .....

Perhaps that, in some countries, associate the words "custom office" and "honesty" is a big mistake ..... :p

I made a mistake, actually. The 5mW sticker did not say that, but the round sticker that's on the aperture (that was there the whole time), says "<100mW class IIIB". Maybe they can't confiscate it if it just says "less than"?
