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 with the striker series the duty cycle is unlimited
and with the challenger 2 the only disadvantege with the 4W 470nm is the one minute on and off (the rest is unlimited)

for you guys who also have lasers that also needs to rest after a minute, is this bothersome and annoying?
or is it something you get used to?

love to hear your opinions
thanks in advance

Whay do you need 3 at the same time--maybe get one and go from there.
It only depends on what you intend to do with it---is 100% up to you- if 1 minutes is good for your purpose than it is is fine.

You can always get both 1 Striker 470nm and 2 of the smaller ones for the other wavelengths and outputs.
is it big? The web site gives the dimensions---get a ruler or measuring tape and figure it out.

Why would it matter what anyone else thinks, wants, or does?

Something you might want to keep in mind is the Challenger2 you can carry most anywhere in your pocket, while the Striker is like a 2-D or C cell mag lite. Hard to carry in your pocket. I have both, they are top notch. You’ll be very happy. The duty cycle you do get use to. Best wishes and enjoy and be safe. :)

Sanwu makes great quality lasers, you can't go wrong with either. But, if you want one that you can easily carry around with you, go with the challenger.

Do you mean 470nm? and no not that much difference at that very high power level..

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

Please combine those 2 posts as double posting is frowned upon here

I’d recommend a beam expander on those higher power diodes as it’ll reduce the high divergence typical with them.

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

:crackup: Nothng to say and just posting the above as a joke?

Do you even bother to read the Sanwu web site product descriptions?
From the Sanwu web site Striker page--
"Ultimate heat sinking -- Starting with a substantial 40mm copper heatsink within inside which surrounded by another huge aluminium heatsink, together the Striker maximizes the heat-dissipation-efficiency a handheld laser could possibly achieve without active cooling." "Duty Cycle - Unlimited"
From the Challenger II page : "Duty cycle 405nm, 470nm (60 seconds on & off), Other wavelengths (Unlimited)"

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 it from a distance into the sky
one minute is just too short for me

edit: omfg i just noticed the striker saber series
is it possible to have it adjusted to 1x18650 battery instead of 2?
if so then it's 100% going to be the striker saber series



1x18650 battery configuration?

No because the voltage will simply not be enough to power it properly. In the smaller configuration you will need to use 2x16340 or 2x18350 which will come to the same size as 1x18650 but have the same voltage as 2x18650's. (Obviously capacity will be smaller than 2x18650s)

I would recommend the 18350's over 16340's as there will be less rattling.

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 FOR MAKING THE PERFECT LASER -

Glad you’re happy with sanwus selection, I guess they have a boost driver and a buck for their saber series.

But please combine some of your posts, you have double posted multiple times.

Make sure you get safety glasses as well.

Thanks
