That laser-thingy sounds like something I’d try building…

This is one of the mosquito laser projects, the original I believe

en.wikipedia.org

Mosquito laser

A mosquito laser is a proposed device that would use lasers to kill mosquitoes. The primary goal would be to reduce malaria infection rates. In 2007, the Bill & Melinda Gates Foundation asked Intellectual Ventures to find a way to fight and eventually end malaria. There, astrophysicist Lowell Wood had the idea to use lasers. Their project received considerable media attention around 2010, but the device was still under development as of 2017. At a brainstorming session in 2007, to think of solu...

but I just read about a new project (oops. same group, more advanced detection, tracking & striking)

That’s so cool. I can tell you it doesn’t take long to kill a mosquito with a 6 watt blue laser. If one of those little guys is zooming around my room I put on good safety goggles and blast it

Lightbringer · 2020-10-22T21:50:05.000Z

Hmm, if they’re “good safety goggles”, how do you see the beam to target the little f’ers? Use The Force™?

Photon_Master · 2020-10-23T17:36:20.000Z

Haha well you can see a very dim dot. I turn the lights off in the room and then crank my Nitecore headlamp to turbo. I can’t imagine how ridiculous it looks

Photon_Master · 2020-10-23T17:39:32.000Z

I like to think it’s a fairly humane way of ending the mosquito’s existence.

Just received my RoxyVon Aurora A9 Copper w/ the Nichia 219C LED with 4500K neutral white tint and 90+ CRI. When I fired it up in the basement, it was “whiter” than I expected until I compared it side-by-side with a 6500K light. Looking forward to trying it outside tonight to see what the high CRI thing is all about!

Now that it’s 2021, what are the options for a 2000K flashlight?

With all of the options Convoy makes available, have they ever offered it? Lately, I’ve been using an S2+ with SST-20 at 2700K with a 45-degree optic. It’s wonderful. It leaves me wanting to try a warmer light. I’d love to get a pretty 2000K light in something like the S21A with an orange peel reflector.

Hank offers the D4v2, KR4 and K9.3 with 2000K E21A.

Simon doesn’t offer it but I have an orange S2+ with 7135*1 driver and E21A 2200k single and 85 degree optic. It’s a really great bedtime light. In a few weeks I’ll be upgrading that to a 2000k and it will then be perfect!

Also have the Emisar D4V2 in 2000k, and awaiting a Noctigon KR4 in 2000k.

I absolutely love my Fireflies NOV-MU with 2000K E21A especially with the 22430 short body.

Photon_Master · 2021-05-11T13:41:33.000Z

Man I’d love for Hank to offer a 2000K headlamp for walking around my house at night. I have the 2000K in a 9.3 and a Noctigon KR4 Ti+Copper

Howbow a necklight? I got one of these

https://www.amazon.com/dp/B08JLFJM5T/

and find myself “wearing” it more’n any headlamp anymore.

Amber/NW/CW selectable, as well as brightness, L/R channels work independently, so you can have amber/brightest on the left, and NW middle brightness on the right, left/right/both as you want.

Pretty nifty.

Photon_Master · 2021-05-12T00:35:04.000Z

Wow dude that looks sweet! Couldn’t resist ordering one, especially with an $8 off coupon

Thanks!

Photon_Master · 2021-05-13T17:34:18.000Z

Man this neck light is sweet. I didn’t expect such great build quality. Not sure I agree with the business practice but it included a coupon to get a $10 amazon gift card if I post a 5 star review.

Photon_Master · 2021-05-13T22:47:32.000Z

Only thing is it’s a little uncomfortable on the back of my neck when I’m sitting on the couch. I might add some foam where it hits my neck. Tried flipping it upside down

Lightbringer · 2021-05-14T03:39:29.000Z

Yeh, even going down the basement, I can just grab it and go, hands-free.

Aussiemandias · 2021-05-14T03:43:35.000Z

Here’s my 2000k desk lamp

Photon_Master · 2021-05-14T03:47:42.000Z

How do you wear yours? The plastic ridge kind of digs into the back of my neck. I like flipping it so the lights point slightly down but that’s worse than when they point slightly up, if that makes any sense

Lightbringer · 2021-05-14T04:09:30.000Z

Got it on now, dunno what “plastic ridge” you mean. Mine’s all smooth and round, nothing digging in.

I plan on building a Convoy S6 with quad Nichia E17A 2000K LEDs from Eurekatronix = Virence . If you have some soldering skills, this is not that hard to do.
