Post Sanwu Guardian 520nm 50mw Laser Review

Completed my third and final Sanwu Guardian video review, this time with the 50mw 520nm version of the laser. I was sent this review unit, along with the 445nm and 405nm versions for the purpose of honest reviews and a giveaway. My review for this one can be found here:



The video contains my detailed thoughts and testing, but here are some brief summarizing points:
-Diode used is an Osram PL520
-Host is very solid and well-built, takes one 18350 flat top battery
-Advertised duty cycle of 60 seconds was more than sufficient; never noticed any significant heat in the host when operating with this duty cycle
-Measured in at 46mw on my Laserbee A LPM, pretty much on spec with advertised 50mw (3 element lens)
-At this power, no burning was really possible outside slight etch marks on black plastic
-Small 1 second startup when switching the laser on. Enough of a delay that it was noticeable, but not an issue for me
-Price is $150. Found this to be quite steep for only 50mw, compared to cheaper Chinese competitors and DIY builds

Pleasant review, very informative. Really like your beam shots in the video. They were just plum nice to watch.

Tried to rep you, but it was no joy.

Got it now. It was a pretty good review. Please feep in mind that these steel hosts transfer poorly, so you won't feel much heat in the host itself.
