It appears you edited your reply. To be clear, I am perfectly fine with the divergence on the multimode diode. It's just that the fast axis becoming the slow axis after passing through the lens is mind-boggling to me. The second article also talks only about the raw diode output.

Thanks, but my question is about the fast axis turning into the slow axis after passing through the lens. This article talks about the raw diode output. I measured it, at point-blank the spot is about 2x4mm, and at about 7m it's about 17x7mm (the 2mm axis expands to 17mm, and the 4mm axis to...

Hello, so, I was finetuning the infinity focus of my Gatling, and I noticed that the axis that starts out wider is actually the less divergent axis, and the initially smaller axis is actually the more divergent axis. Is this normal? I can't wrap my head around why this would happen, I believed...

According to the article I linked it actually takes 8X the power to double the brightness for the average person. Pretty sure I'll go JetLasers. I like Sanwu, but their lasers are more on the artistic side, while JetLasers is more on the functional side.

If the difference isn't huge, then I think I'll go for JetLasers. Also just remembered the PL-E Mini has a protective outer lens, which is another plus. Depends on what you mean by huge, of course.

I've been thinking a bit more about it, I believe the difference between wavelengths is directly proportional. I found this article about how percieved brightness scales with power, and turns out it is proportional, on average, to the cube root of the power difference. I also used this table to...

It's a 40% power difference, it will obviously be noticeable side to side. But just how big is the difference? I'm not sure if percieved brightness is proportional to the power or to the square root of it. I personally belive it's the square root, as in my experience the difference in brightness...

He said the bare diode can output 1.2-1.3W but they keep it at around 1W due to lens power losses. That would be around 80% efficiency, somewhere in between a 3-element and a G7/G8. It would cost me around 50€ extra (333€ vs 280€), I prefer the Jetlasers host due to the higher heat capacity...

I emailed Gray asking if they could sell me the laser at 1.2-1.3W, even if it costs a bit extra. Waiting for his response.

I sort of figured that out meanwhile. I just wanted to know people's experiences to see how likely it is for customs to seize the laser or charge fees. Your last paragraph is the answer to my question. If that's how it is, I'll probably get it. Also, do they declare it as costing 20$, like they...

Hello, I am planning to buy a JetLasers PL-E Mini 520nm 1W, but I'm afraid of it getting stuck in customs, and having to pay fees. I live in Portugal. How often does that happen? On the JetLasers website it says "There always no extra customs fees.", but then they say the customer is fully...

Thanks, I was hoping it would be overspec, meanwhile I found a review claiming they got 1200mW. Thanks, I'll probably try that. They are a lot more expensive though, and I prefer the functionality of the PL-E over the looks of Sanwu stuff.

Hello, I am thinking of buying a 1W 520nm PL-E Mini, but I'm not sure about the power level. I know it won't be underspec, but I want to know if they are usually overspec (something like 1200mW). Has anyone tested it?

Sorry for the necropost, I bought 6 of those 16340s and the difference is incredible. They last FOREVER in comparison.

As I said, I live in Europe so the shipping costs as much as the lens itself.

I know it has the correct threading. What I'm scared of is the fact that the G7 appears to not have the ridges to screw it in, therefore if I need to screw it in too much I won't be able to.

Hello, would a G7 lens from Sanwu in a 9mm holder work with a blue Gatling laser? I am thinking of buying one as the stock lens is getting dirty and I can't get rid of some of it. Would there be any problems due to it not having holes for a screwdriver, therefore being unable to screw it into...

I don't have the equipment to measure that. They are LC brand, rated for 1300mAh (obviously not true), weigh only 13g compared to 18g for quality batteries, and charge fully in only half an hour. The ones I linked are truly 850mAh up to 1A, from HKJ's test over on BudgetLightForum. Thanks for...

So, I have a blue gatling laser. The included batteries are really bad, and I am thinking of buying quality ones. Just how much of an upgrade would this be, considering that the power output starts to decrease after less than a minute of continuous usage with the included batteries? Could they...

Are the AW 18350 900mAh batteries sold by Sanwu Lasers good quality? Because I remember reading that the 900mAh ones are fake.
