Did you ask for it to be that long? Just curious, I feel like a build using only a single 10440 would be small like a sanwu pocket unless you just wanted more length. Looks great though

If you put it in your pocket with nothing protecting the lens dust can easily get on the lens and you will notice. It's not hard to clean with a q tip. I just use a tiny bit of water on the tip and then use a dry one to wipe it clean.

Wow wow wow. Sensory overload. You have blown my mind-balls.

Well, ultra fires arent know for quality. I dont believe 7800mAh. I'm not sure plugging the unit in is a good way to charge them. I recomend a separate charger like a nitecore. The laser sounds and looks very much like a jetlasers clone. You can have one made by members here for a pretty...

The laser on that site looks more legit than others I have seen. Not 100% though. Traverse mode TEM00 on a 5W blue? Um no. 2mrad divergence on a 5W? No. Try again. Also not the most powerful one you can get but a lot of places say that dumb crap, at least it doesnt call it "military". Also...

It's hard to tell from your pics and description. If I had to guess, I would say you need to adjust the lens in the focus knob. I used to have a laser like this, they're pretty common and not super well made. The lens should have slots for a screwdriver of the correct width. If the laser never...

Judging by the stated divergence I would say its a multimode diode. If it's the same type as the one i got put in mine a while back, 1W is not really pushing it hard, as they can be pushed to 1.8W(ish). Dang...$350 for that. If it were me I'd get one elsewhere or make one/ have one made. Unless...

I agree with what others wrote and I would add that most of us probably arent too keen on this "for pointing at $@!t" concept, it's kinda vague and gives an impression of carelessness. When I let others see mine, i tell them it has the same rules as a firearm; be sure of your target, make sure...

IR light from unfiltered dpss lasers applies mostly to 532nm lasers. 520nm indicates to me that it is a diode laser, not a dpss, which is a good thing.

Yeah dtr has the mm 405s

I cant tell you which to get because my two favorite lasers are my 1.6W 405nm and my 5W 445nm. (My 5W is kinda old so it's not as powerful as it used to be and the driver was never turned as high as it can go, but it is the type of diode that produces 7W) I can say that I do love the powerful...

Should be visible but not too bright. Depends on the angle it is viewed from too. 90° is least visible and the closer to 0° or 180° you get, the brighter it will appear. Also, laser beams appear brighter when pointed toward you than away. The lasers on such harps terminate on a sensor right? I...

Works better eh? So more output, or the same? And gets rid of artifact?

It's fine, I'll keep it. I would recommend checking the output of other lasers you meter against the pics on DTR's site, whenever you're using the same diode. If your numbers consistently show higher mW output than his pics at the same current, and with the same lens type, there's a good chance...

I have never calibrated it but it seems to work well enough for my purposes. I think it is still pretty accurate. Like I said it matches what rich had sent me, and every now and then, I shine a 5mW on it to make sure it's still sensitive enough to measure low power. Not even sure how to...

Well the sensor surface is recessed on mine, so I'll place it as close as I can, with the head in the opening... Didnt make a difference.

I assume it's a ugm02, it is a 525nm, and I see a clear difference in color between it and my 520nm. Also it is decanned. You're right, dtr's page does show I'm within the normal range for that current. But part of why I got it was I thought it was a freak diode, super efficient. Oh well. Guess...

It was decreased to 1.8A, but he had sent this pic to me. Yes batteries were charged. My LPM may not be in PERFECT calibration, but I recently metered a build from rich which showed a very similar number to the one he sent me a pic of

Well, the good news is I got it. The bad news...
