Enlightened
I picked up a handful of the newly released Steve Ku Veleno Designs Quantum DD flashlights recently. I was eager to get home and take a photograph and write up a 'first light' review. I hope you enjoy this and find it useful. I'll be updating this thread with beamshots and a video tomorrow evening in part 2 and later in the week I hope to add part 3 with tritium installation video and photographs. I'll be happy to incorporate and suggestions you may have as well. Thanks for reading!
These lights are available now from Illumination Supply. Here is the sales link. Here is the teaser thread.
With the XP-G R5 LED and a 10180 LiON battery (included) the light will make up to ~100 OTF lumens for up to 8 minutes. Adjusting the light to a lower output level will dramatically increase run times. This is a lot of light to have on your keychain. The light is about 40mm long (just over 1.5") when the threads are closed just to the point the light comes on. And boy does it come on, through a highly efficient 34 degree TIR flood optic
I personally feel this offering as a whole surpasses its inspiration, the custom 40DD of which I had eight. The packaging is top rate, right down to the brief instructions on the package. You get the Quantum DD flashlight, battery, charger and a split ring. IMO, a great value for the MSRP of $60.
I have some 1.5x6mm Tritium vials (Optional and purchased separately in pairs for ~$20) on the way. They are terribly easy to install. You just drop them in the two holes on the end and dab on a bit of Norland or Silicon and you're good to go! Silicon is easier to obtain, cure and remove, but Norland cures clear and reveals the end of the trit better. In either case the sides of the trit show identically though the fins and create a sort of 'dot matrix' effect. I'll have pictures of that in part 3 of this review along with a brief 'how to' video.
Shown for size comparison. The Quantum has the same exact size, quality materials and build as it's custom parent the 40DD. It also comes with a unique USB charger. How cool is that?

The light comes with simple and effective packaging. Minimal, attractive with clearly written instructions and a diagram.

The Quantum is 40mm (1.5") long, infinitely variable from 0 to 100 Lumens OTF output through a TIR (Total Internal Reflection) lens. It comes with a convenient and safe USB Charger, 10180 LiON battery, spare o-ring and a split ring. The included charger is tidy and securely houses the LiON battery with no issues shorting out leads or dealing with magnets not adhering to non ferrous battery cases.

Quantum DD shown sitting atop a Kevin King Leather Sharkskin Attaboy minimalist front pocket wallet. In this shot you can clearly see the holes on one side where you can slip in a 1.5x6mm tritium vial! Just top it off with a tiny spot of NOA61 or common Silicon adhesive to set it in place.

Smooth threads make it easy to adjust the light output infinitely by compressing the QTC (Quantum Tunneling Composite) pill at the base of the light. More compression causes more current to flow and drives the light to higher output. The Quantum DD produces ~100 lumens OTF using stock XP-G R5 LED for up to ~8 minutes and the included 10180 LiON battery. If you fiddle with it, the output can be adjusted so low as to be almost on par with a Tritium marker! Lower levels will yield much longer runtime of course. If you need a few moments of room or street filling light or a low light to read with, this will do it!

Each Quantum DD is individually serialized, 1 through ???. Random numbers are shipped though we've all got our favorites. Who will get lucky 888?

For fun, 5 of my Quantums were modified today with a Nichia 219, Cree XP-G G2, and Red, Green & Blue LEDs. The modification is extremely easy, but will definitely void your warranty. Just carefully reflow a new LED to the mount plate. These are 'Direct Drive' flashlights, so there's no electronics to cope with.
