It arrived today! So in went an Orbitronic 18650 Protected battery. It started in 1 mW mode. I was able to switch it to half and full power easily with tail switch half presses. This switching requires a protected 18650 within a certain range of length. I've written elsewhere about that- so I...
A great product indeed! Working nicely.
This is really a heads up for anyone having issues with switching modes on the Challenger 2. Luckily SanWu has excellent Customer service.
Li ion batteries- no prior exposure.
I learned that the Lithium ion batteries are named by...
Just for fun. My Sanwu Challenger 2 (sharp 490 nm) pointed into an Ultrasabers light saber blade.
Not attached -just pointing in. With a ring adapter and a set screw it could be attached.
What would be better would be to take a replica LED lightsaber-with motion sensing and sound-and swap out...
I wanted to get the waterproof 505 nm reviewed by LED_museum.
I can't find it anywhere on EBAY-although there are many offerings of the 488 nm version.
I only found it at the "Laserpoints.com" store.
Any experience with them?
I now get Spam adds from them. Just in 50 W hand held gatling Laser.
Do they have no upper limit to their absurd claims?
If you drove a 1.4 Watt capable 445 nm LED with enough current-would it output 50W for some fraction of a second before failing? Resistance generates heat-so maybe...
I am in no way challenging Sanwu. It was marked 492 on the wrapping. Paul was thinking it looked more like 488 and I know he has compared many of these diodes.
But perception and photography are both fickle! I'd call this aquamarine.
So I set my Canon 5D MKIV on RAW, took the laser lens off and...
I was excited after weeks to get my Sanwu 1 Watt module back-multimode was stuck on 1 mW. Looking good- 5 half presses-bright beam- then POP! Smoke out the back. Now it's dead altogether.
This is frustrating with a new laser. I think they should send a replacement module.
Does that seem reasonable?
a friend sent me this link. Looks cool. A 405 nm Cube with USB-fun for kids.
I don't see anything about eye protection-which is a concern. The video makes it look fun and safe. Not good!
After some reading-I noticed that Ultrafire Batteries have a BAD rep.
I have two that I got with a "Gattling Laser" within the last month. One is officially DEAD already.
I'm glad I followed advice on the forum about battery chargers-I have a Nitecore D4. I was able to recharge...
I took the plunge and bought a quality laser from Sanwu. The 1 watt Challenger 2, 520 nm 1 Watt Multi-functional version.
Initially, I ordered a 150 mW 525 nm-but changed my mind. I must say it was very easy emailing Francis-and changing my order. Then it was time to wait.
Total? About 7...
I have one of those common 445 nm "Gatling lasers"- and I ordered a Sanwu 3X Beam Expander for it-which works perfectly. The only issue is that the host starts to get warm after a minute-or less. (I shut it off for awhile-having read the forum on the subject)
I am focusing it on a...
I am new to the hobby-I've been reading about DPSS vs direct diodes and if I read correctly, the 532 nm are DPSS and get to 532 nm via 1064 nm infrared (which is also why cheap 532 nm put out an invisible infrared beam-no filter).
I have a 520 nm 1 Watt (Challenger 2( being built by...
Recent owner of lasers wanting to learn-and have fun (safely!). Reading the post before posting-is always a good idea. :-) I have Goggles (Eagle from Survival Lasers)-they don't seem to have GOOGLES in their catalog.
I own 3 currently. A Green (532 nm) pointer "Rapidly Cat Toy" from...
