This guy has some nice looking lasers with impressive specs and prices.
8w 470nm US$195 with shipping.
Does anybody have recent experience? I only found some old posts.
The red dot did not make a new appearance with almost discharged batteries. If I were you I wouldn't believe me, but I swear I wasn't using any hallucinogenic drugs. I have seen it before. If it makes a reappearance, I will grab a photo.
The lasers are Sanwu Challenger II 445 nm 3 W and Sanwu...
I went to get a photo and the red dot did not appear. Both lasers were running on low battery when I saw the dot. I didn't know this at the time. I just put in fully charged cells and there is no more dot. I'll discharge them and then get a photo.
I was making a list of the parts I would need to make a laser. DTR's Laser Shop has a 4W 465nm Diode in 12mm Module for $65. The No-Diode Host bundle at Survival Laser, capable of driving this diode, costs $240. Jayrob's NUBM07E 465 DMag Shorty costs $307. Total cost is $305 - $372. The Sanwu...
I have seen mixed reviews for Laser Pointer Store here on LPF. Their prices are 30% or 40% lower after shipping compared with buying from Sanwu lasers. Sanwu charges $40 just for shipping. The only negative I've seen is Laser Pointer Store does not have the newest Sanwu products. I bought a...
If I only need 10% accuracy, will it do the job. I'm new here so I'm not sure of my accuracy requirement. There is a new 20 W LPM on Laser Pointer Store. $145. Is it also a toy?
I looked for reviews on YouTube but could not find any. It is new at Laser Pointer Store. Price is $145. The reviews for the Pocket Laser Power meter are not great. Accuracy is about 7%, and it can't truly measure up to 10 W. Does anybody know if this new LPM is good? Accuracy, fast response ec.
I did, and they just gave me the spec from their web page. Like I said in the OP something is not right. A 5 W 445nm would have much more heat to dissipate than a 50 mW 505nm. Also, Laser Pointer Store has different specs for the same product.
I did find a good answer in one of the Official...
I ordered the Sanwu Challenger II 445nm 3W from Laser Pointer Store. It should arrive tomorrow. The Sanwu web page says duty cycle is 60 s on, 80 s off for all Challenger II lasers regardless of power and wavelength. The Laser Pointer Store web page says 405nm (60 s on & off), other Challenger...
