1. When a manufacturer says that the battery size 14500 needs to have a minimum of 6A continuous, what would happen if a 3A battery was used instead? Would it just be dimmer, or would it not work at all, or would the drain on the battery from the laser actually be dangerous and cause the...

Not even sure if that's what it's called, but I think you get the idea. When I use my laser and am near a wall, I notice a splattering of light that emits directly to the side (and slightly in front) of the host. There is also such light on the opposite side but nowhere else. I just wanted to...

I had a 1.5 watt blue laser about 6 years ago and it was my first high-powered laser. It only lasted for 9 days, so videos I made are all I have left of it. I heard that green lasers are much brighter due to our eyes being more sensitive to that color. I just bought one of those and got it...

I know a 14500 battery is 3.7volts while a AA is 1.2volts, but would it still be safe to charge a 14500 battery in a charger designed for AA batteries? The size is the same. I figure it would just take maybe 3 times as long to complete the charge, but maybe there's more to it than that. I'm...

After getting advice on which companies to deal with, I checked out Sanwu and was drawn to this one: https://www.sanwulasers.com/product/304 Green, 80mw, and only $20. Not bad! So I selected it and went to check out and saw this: https://www.sanwulasers.com/checkout/wrii351xexpxdixa3rdllpif...

I've read the many postings where it is said that laser goggles are mandatory if you don't want to suffer any damage. But then I always read posts where people say something like, "Wow, this laser's beam is so incredibly bright!" But if the safety goggles filter out the laser's light, then they...

After hearing so much about how lasers sold through Amazon are very overpowered (or at least some of them are), I was hoping to get suggestions as to which of these would be a good deal. What I would like is one where the beam is clearly visible. The "legal" ones people use as cat toys don't...

I posted an ad back on Friday and now 2 more days have gone by and it has been neither accepted or rejected. The rules say that it has to be approved before it becomes visible. I assumed I'd be notified if it didn't get approved. Does anyone know if that section is still operating normally...

Selling my SF501b 455nm blue laser, which was originally a 1.5—1.8W. It no longer outputs the way it used to, which means the diode may be fried, or something else is wrong that needs fixing. It only puts out a very weak beam that can only be seen in a very dark room. I’ve already charged up...

I just received my SF501b 1.5--1.8W laser from Scifi lasers and now the focusing ring came off and when I put it back on, the only light that comes out is similar to a flashlight. I only had it for 6 days and now it's not shining like a laser anymore. FWIW, that focusing ring needs to be...

Here’s my review of the Sci Fi Lasers SF501B 445nm blue 1.5—1.8W laser. It’s my first review so I hope I end up doing a good job of it. I ordered it on Feb. 27th and it was shipped on March 9th and I received it on April 1st. So, a month and 3 days. Placing the order was pretty simple and...

I noticed something that is common in all the videos I've seen where burning things, lighting matches, popping balloons, etc. is done to show the power of the laser. At the beginning, we see the laser being turned on, then a match or whatever is placed in front of the beam. One thing that...

I understand that tests would have to be done in order to know exactly how good they are. But judging by the color alone, would these be good for at least a majority of needed protection for a 445nm laser? I've heard red is the color to have for a blue laser, but I've also heard orange and...

I noticed that when lasers are battery powered (and batteries and a charger aren't already possessed), the batteries and charger add a lot to the cost. So I was wondering about getting something that plugs into a wall outlet. Makes sense if going outdoors with it is something that would only...

I've noticed that all the talk about blue lasers are all about their burning power. When the talk is concerning green lasers, then it's about using them to point to things. But if the power level of a green laser was increased enough, they burn things as well. Also, I noticed blue lasers...

I've been looking at the idea of buying a higher powered laser (between 1W and 2W) and I live in the USA where such items are apparently legal to own, but not to manufacturer or sell. So the only option is to either buy one overseas and hope it doesn't get seized by Customs, or build one...
