DQG Slim Extension Tube Light Builds

I got to thinking when I saw the DQG Slim 14250 ti flashlight and available titanium extension pieces....

And come up with these little fun builds.

I liked the idea of the DQG Slim flashlight with it's form factor, tail switch and ability to use different cells with the optional extension pieces but figured it would be a little slippery in it's 14250 configuration which I would mostly use plus I have always liked lights with knurling over the whole body of the light so these builds seemed sensible -ish to me :D

Put simply, amazing. :beer:


Efficient Magnificent !

Yes amazing, is there anything sir CRX can not do! 8^)

Thanks mate :THUMBS-UP:

I hope not :wink: :THUMBS-UP:

Detailed and simply awesome build. :beer: :THUMBS-UP:

:slight_smile: :beer:

As always CRX, your builds are over the top :beer: .

Love the build quality, but I’m not so fond of the most striking element….optics.
Have you considered adding some reflectivity to the optics sides? Not it looks like you have light running out and banging on the body sides…maybe even a white paint would help? The way it is, is it really any brighter than a single LED?


Thanks mate.Yeah I knew this before I made it, not the best use of the triple setup like I said in the OP.
Maybe even a straight mule would output more light but I wanted a triple and a bit of a focused beam from this.
I did polish the optic sides back up, paint or mirror tape would not really be possible here but I’ll have a think about it.
Like many of my builds I’m not always looking for maximum efficiency, just seeing if it can be done :THUMBS-UP:

Another sweet build :THUMBS-UP: I like the look of this one even with the odd looking optic :beer:


You never cease to amaze , CRX .
Great build and thread .

NIIIICCCEE———- I always enjoy your builds —- learn little tricks—— now to go build something

Superb :LOVE: True scratch-built EDC 8^)

Any beamshots? :slight_smile:


Thanks Jack :beer:

That’s the spirit :THUMBS-UP:

Cheers mate :beer:

Ive been thinking of a build i wanted but wasnt 100% on sanding optics down, your beamshot seemes quite good. What was the original diameter and how much did you take off?
