Hahah I also have that one too. I don't think you can get that emitter seperately, at least not on DX.

Sweet glad they do have a bare emitter. Those lights are certainly bright. I would compare it to the Dorcy Jr in brightness. but of course since it's UV you don't get to see the true power of it. I walk into my childrens room with all thier flourescent toys and it blows my mind!

Heh I have that light too  :)
It's bright for a violet light, little brighter than a PHR on a 18650 cell. I believe it can be much brighter two cr123a cells tho.

Here's the bare emitter:

Hey I finally slapped one of these UV emitters into a (new style) 4171 host and it is awesome! :cool:

It was so simple to just exchage the bare emitters! I used a little thermal adhesive and then just soldered the tabs....

I checked voltage to the emitter using 2 X 3.0 volt Lithium primaries, and it was 3.6 volts at the emitter. Very bright, and makes things glow just like a blu-ray laser! :D

Thanks!
Jay

It was a good idea to drill out the tailcap to get a longer battery in, eh, Jay? :angel:
I came up with it when a machinist Teenie buyer showed me the host for the first time, and i asked if it's possible to do, and he did it perfectly on his lathe!

Your idea to undress the battery from below allowed the 10280 in in the end!

My laser in this micro-badboy now does 240mW with the medium custom lens!!


I need two more Jay, machined for an AixiZ press fit! The first was a Sure press-fit, not that i mind, but then i can't get your lens in...

Sounds like you like my 'thicker' Key Chain host huh Igor? :)

But do you have the 10280 batteries for them?

I love it! It's mass is amazing, and it can keep a diode from overheating for up to 10 minutes!

My host has a slightly more massive head, but the body is thinner. And shorter...

The result is a thermal blockade, i'll explain with some drawings...


With yours, the heat just flows down from the head into the body, and i love this about it, must make a GREAT CREE Flashight as well, especially with your little heatsink!

Yes, I have about 4 of them in Flashlight mods! :)

I'm in the middle of a Q5 flashlight mod with the Key Chain CR2 host as we type. I'm waiting for my thermal adhesive to cure right now...

I will show it later tonight in a different thread...

Hi,
I saw above you had looked at Mouser,and possibly Newark for switches.Other companies I have used in the past for non-laser projects,that carry obscure parts are Digikey,Jameco,and Alltronics.Check them out.Hope to build some lasers of my own in the future!

Wow. Good job! I DIY seldom. But i think a DIY keychain is a good souvenir item for friends, of course, it is also a novel decoration.
