OMFG YES! francis just confirmed that's possible to have the 1x18650 configuration if you want to that means 2 x 18350 batteries will also work with the size of 1 x 18650 for no power loss making the full power of the striker series into a somewhat handheld challenger 2 size - THANK YOU SANWU...

ok i think it's decided it's going to be the striker series (even though im leaning towards the challenger 2) i just tested out the one minute on / one minute off with my other lasers and that is just a no go and extremely annoying because im used to let the laser on the tripod and gazing at...

Thank you

is there something wrong with the sanwu website? it seems like the website is totally different

yes im buying the 3x expander for the 470nm since that one has somewhat a bigger divergence the 520nm should be fine i think im going to buy the challenger 2 the challenger 2 is fully made of copper so that should be a better heat conductor as well while the striker is made out of stainless steel

Really leaning towards the Challenger 2 Because if you put the 3x beam expander on the striker series it will be massive overkill

Yes i Mean 470nm Typing error, my bad

is 4w and 5w 570nm a big difference? because im leaning towards the challenger 2

Hello i wanted to ask you guys your opinion on the sanwu challenger 2 and striker series because i can't decide i want to buy the 1W 520nm , 4 or 5W 470nm and 1W 635nm the challenger 2 and striker series cost approx. the same the striker series is bigger but is it very very big? i know that...

thank you all for the great help i appreciate it !

it's going to be 1W 520nm, 4W 470nm and 1W 635nm it's all above 1W so i hope the beam will still be "very" visible or at least i hope the 520nm will be thank you

Hi So the beam expander Will not decrease beam visibility? I thought by expanding your beam it gets watered down because your beam is not as focused anymore without the beam expander

Hello i wanted to ask if some of you guys have experience with the sanwu laser expander https://www.sanwulasers.org/product/x3beamexpander it expands the beam 3 times with it but does this also mean that the beam will be watered down (more transparent) ? so when looking at the side of the beam...

thanks for all the good info guys i don't know what driver it's going to be because im going to buy them from sanwu 1W 520nm - 4W 470nm - 1W 635nm anyone have these sanwu lasers with more info on the driver?

Hey Alaskan i have no idea but it doesn't matter Thanks you are a great help

im sorry i've been here since 2012 (buying groupbuys from laserbtb/skylasers) but i forgot my account information i didn't really wanted to make a welcome post since i did that over 6 years ago thank you

hi thanks for quick response what will twice the voltage do? (sorry for dumb question) so after reading your post i think 1 x 18650 battery will be the better option?

Hi i wanted to ask what is the best and what advantages/disadvantages is for a laser with the option for having: 2 x 18350 batteries or 1 x 18650 battery will the 2x18350 batteries will give me more power? the lasers are 1W 520nm and 4W 470nm if that would make a difference thank you in advance

wow 1988 that is ancient i did not know people were already buying lasers back then :wtf:

Hey Yeah i bought couple aw 16340 almost 9 years ago for my laserbtb lasers I'm surprised, i didnt knew they still existed as long they won't explode or anything I'm good I guess using a nitecore i4 charger so that system should prevent me from overcharging Catching a fire?
