You'll need to make something yourself for that non standard lens. I recall way back in the day when 405's first appeared someone made a custom lens holder for one of those lenses, the beam was pencil thin and great for burning up close but the divergence was horrid and the projected spot had...

The variety of high-powered blues is staggering. Do you have plans to run the same comparative test with greens?

This is gold! Amazing data, thank you!

Im interested to hear more on this

https://www.ebay.com/itm/116107201461 Thats one pretty tube

NEED! Can owners of the current Valkyrie 573 trade up for the new one? Paying price difference and shipping of course

I'm loving all these power tests!

Shoot dang she’s an angry little diode. Off all the high powered diodes we’ve had over the years the NUBM0G is still the most impressive in my book. Crazy power and a beautiful color

Nice! Those attachments came out fairly recently, this is the first time I've seen one in the wild.

980nm is an odd wavelength that I haven't seen very often in handhelds (most folks around here like pretty colors). Here are a couple modules in 3W, 2W and 1W as well as a bare 500mW diode that could be made into a pointer if you desired. https://www.ebay.com/itm/334926470537...

I don't recognize that host, is it handmade/custom?

Big Lasers is scam site, they use stock photos from other sellers and don't deliver what is advertised

Yup I think those have one extra diode per string compared to the 125W model

What diode are you using, most diodes are case neutral or positive with only a handful that I know of being case negative.

For replacement you'll need something like this. https://www.ebay.com/itm/363223371935 I don't know your laser so I don't know what diameter and what focal length you'll need but this is the type of part you'll be looking for. It expands the 532nm light fresh out of the crystals to then be...

Oh wow that's no longer a good deal, sounds perfectly plausible that they would pull the listing just to crank the prices. What a shame.

Nothing yet unfortunately but I'm keeping a look out for it.

I'm running 4.2V rechargeables in it so its no problem to just pop them back on the charger. Normal CR2's are way too expensive to keep buying. If it were still in a mount I could get the diode quite hot but as its already in a pointer I was only willing to let it warm up to what I would...

Holy crap thats insane
