KC1 keychain light is available now

What can you use them for other than finding questionable stains?

They’re fun to shine on stuff in the dark and watch colors fluoresce. I think people use them for exploring caves and looking for scorpions

It gives you the ability to see even more stuff with your lights, so count me in!

If you’re just out for fun, then they are great. I walked around my basement at night when it was pitch dark and watched everything glow in different colors. Super cool… I’ve been wanting to go explore a cave or something and try it out

UV - remember to wear eye protection.

Now that I have a few Uv flashlights, I use them for urine staines, money fun, scorpion location etc. These flashlights will also cause many rocks and minerals to fluoresce. Go to a gravely beach in MI or any river and enjoy the night time show. Sometimes short wave works better, sometimes long wave. Turn one on in the clothes closet and gaze at those whiter whites. Guys: Best not to let significant other use one near the excusado, lest your daily workload increase. I’m hoping Sofirn will build one of their dive lights with a short wave bead in it. Would be interesting under water at night que non? Uv dive lights are expensive and I’d like to see one in the $40 range.

please take a picture!

Here are a few things: https://budgetlightforum.com/t/-/49853/2

Hmm, interesting. While I think corals and other things might fluorescence nicely I would expect that water absorbs UV quite effectively, dimming your light a lot. Anybody know for sure?

I use mine for many of the things scientist linked to as well as charging the lume on my watch and fishing lures. Also it cures special adhesives too.

Cool! I didn’t know one of these was available. No sign of it earlier today when I ordered a D4v2 in a deep red. I’ll shoot Hank an email and find out how to get one. One thing I really like about the D4v2’s is you can pop the optic out and put the lens back in and it doesn’t flop around. With the FW’s, the lens seems to rely on the optic/reflector to stay in place. Geez….the collection is getting a little out of hand……

Good to know about being able to pull out reflector and lense still stays in place. I assume to make a “mule” of sorts? I’m going to try this .Also, maybe an appropriate sized oring would help in case of fw3a, or a light where lense was moving?

Ordered my second k1 yesterday! Only took about a week with my first K1 to start assessing my other throwers and which ones were going to get cut. Pained me to sell my convoy L21a CULPM1, but ordered the k1 with CULPM1. If this K1 W2.2 feels like it’s worth $50 more then the convoy, then up next on the chopping block will be the ft03s…

Can Anyone share a picture of the “dark gray (close to black)” colored K1? Is this the same dark gray Hank still has on the website, that looks brown in some pictures? Or has that color changed since the K1 was released? I know Hank slightly alters the colors sometimes (I.e. the new green d4sv2 vs. the pictures on the website of the green d4sv2).

Yes - I’m doing this with the D4v2 in 3500k - having a wide soft flood is excellent for an indoors / caravan lamp/bedside light. Will try the o-ring trick but I’m thinking there’s nothing to stop the o-ring from falling back to the led once the reflector is removed. An inner sleeve may work - although now I have a few Emisar/Noctigons, I’ll just use these if I want a complete flood. UV mule incoming.

Any idea when the copper d4v2 will be back in stock?

Be careful with this! I believe there’s nothing holding down the mcpcb firmly to the shelf except the stickiness of thermal paste. No additional screws as far as I know so the mcpcb might lose the direct thermal path at some point which could be disastrous.

Yea that is so true. If it’s not screws down that may be a really bad idea

Do the two phillips heads screws in the center not hold it in place?

Yes, if there’s screws they most likely hold it down

Silly me, I forgot the D4 had them. Yeah I just took a look at mine and it looks like they do keep the mcpcb securely in place
