I placed my order for a 30 mw laser and some lights, leds from dx when this thread started and today, almost half the things I ordered shipped!

I just wanted to let you know rob, I have a pointer from Atlasnova (~27.5) and I can see the beam on even a barely dark night outside. I can see the beam inside the house, I can see the dot on a sunny day outside from a balcony, and it is very easy to see the beam indoors without smoke/fog. I also have another leadlight 110 (LED version) and you can see the beam at 5mW pretty easily. It's not a solid beam, but you can see it. You can see the beam indoors without fog/smoke, but it's not as bright.
I also wanted to point out that this is exactly as it says it on the DX website:
"As discussed at our forums, this laser does not come with an IR filter. So for safety you should wear protective glasses when using the pointer."
In the case of a LASER as such, most of the power is IR, about 75% or so of it. So be very careful and make sure you wear eye protection. Damage could be happening to your eyes and you wouldn't be aware of it. With a 30mW greenie you get the reflection off white or shiny surfaces and it makes you close your eyes. With this one, you are only aware of the green part, and the vast (and usually less focused) IR is completely invisible but still very harmful.
Good luck;

Well, I've tried every battery in existence and my DX 30mw peaks at 17mw. I'm very dissapointed with the output power of this compared to my modified leadlight. Now My green led power meter may not be very accurate but I'd have to say that it's pretty close. still half the advertised power is not impressive. of course for the money spent on it it's still a very bright laser. I paid $250 two years ago for a 15mw laser and it certainly beats the $99.99 sticker price for the WL Exec 15mw. Laser weighs a ton compared to my leadlight.
Anyone tried pulling one of these apart?

Oh and mine does have an IR filter.

Kenom,
That Green LED meter method has been shown to be VERY unreliable
You could be getting almost any reading on it - and none of it accurate. I have a power meter, as do some others on this forum - and I would be happy to test it out for you. Just let me know, I can test it, and send back to you when finished.

I haven't been able to get that site to come up all day.

Hi Kenom,
Thanks for reporting back. I guess I am still on the fence, but the price isn't bad. I am happy to hear it does have an IR filter. If you send it to Senkat, I will wait for his measurements. Thanks again.
P.S. I really like the nerf gun. Sorry the laser burnt out.

Woohoo! Since my thread about getting my 30mW DX green laser through customs got closed, I figured I should post here about it. Got it today along with my Ultrafire C2 replacement part, and boy is it awesome. It's got a nice bright beam, doesn't take long to warm up, and likes NiMH and alkalines just the same. The only problem is that the beam comes out of the end of the pointer slightly crooked, perhaps 5 degrees off the axis of the pointer. It's been a long time waiting, but I am glad it made it! The package had a green piece of tape on it indicating that the Dept. of Homeland Security scanned it, but no FDA labels. I am soooo happy that it made it through the 5 day stint at customs.

Hoooray glad you got it. I am going to be shipping my dx 30 to SenKat for testing on a real power meter. It saddens me to hear the led power meter is so ineffective as I bought a new multimeter with a ammeter in it so I could test the power output on my nerfaser. Man was that thing bright. Cut black tape, popped rubber gloves, sting greasy hands. (wipes tear from eyes) I realize now how truly pathetic I am that I lament the loss of a laser so much.
Has anyone taken apart one of these badboys? I've tried to pull off the top to clean the optics but can't twist it off. Would like to know if it's potted. Not that I would modify this (at least until I get another high power greenie mwahaha)
Why can't I resist the temptation to modify???

I don't know why you can't resist your temptation, but I know that if it can't be modified, you don't want it.
Or at least that is what I heard anyway...

My 30mw laser (not from dealextreme) can pop a black balloon. It's got an IR filter.

my 30 mw dx greenie finally arrived today.
tomorrow I will measure the output with a spectrometer (hom much ir is in there anyway?) and of course the power.

No ir. it's filtered.

Can you take day and night shots as well? I'm almost ready to buy one, but am dieing to see more beamshots.flashlightpoor said:

30 mW DX laser MEASURED!
I finally received my dx laser. I don't think I have read a single post on this forum of someone who measured their laser with an actual laser power meter. There's speculation of the power, the IR, etc. I was so excited!
How much power?
I just finished measuring mine. Using a Coherent power meter I measured 24 mW with the included batteries. With fresh alk. batteries I measured 32mW. After 5-7 seconds the power declined as the batteries were likely sagging.
How much IR?
First I used an ocean optics spectrometer and measured only a single line, centered at 532 nm and about 10 nm at full width half max. There was no IR, but the ocean optics' range ends around a micron, so I wondered if it just wasn't detecting it. I decided to try filters.
First I used a long pass filter and using the power meter found no energy above 700 nm. Next I used a very good bandpass filter centered at 532. I measured the un-filtered power and then the filtered. If there were IR the readings would be different.
What this means is this laser has a very good IR filter. the resolution of the power meter is .1 mW so I can confidentrly say there's no appreciable IR coming out of this laser. Of course yours could be different, different parts, assembly etc.
next I am going to take it apart and build a better power supply so the batteries don't tach out after 5 seconds.

Flashlight poor - that is an excellent series of test there ! Thanks for posting all that info - that is great to have !!! I am jealous...I wanna get a spectrometer !
I got my DX this week and I am very pleased with it. Pops balloons at 36" easily with included batteries.
However, has anyone looked at current draw on these?
On a fresh set of batteries 3.2V it's drawing 370mA. Does this sound right? Seems excessive for AAA batteries. But, since it's an extemely lossy conversion for green, and it is a 30mW laser for $30. I can understand why.
How does this laser fare with other battery chemistries (NiMH, Lithium, ect.)? I'm hesitant to go to a higher capacity in case internal battery resistance was a factor for regulation. I'd hate to break a new toy that took a month to get.
I can see DX will become my new favorite hot spot for bright and blinky things.
