    Good afternoon everyone, I'd like to share a project I've been chipping away at behind the scenes for a while now.

    This is the "Corvus" project, a conceptual successor to the Hyperion, intended to eventually be made as a AA/14500 compatible light once a driver is available to use. Overall light design is shorter at ~100mm OAL and a bit skinnier than the Hyperion with a smaller 20mm diameter head. As usual for me, this is a manually machined custom light.


    Intended design elements are a smoother and more compact variant of the titanium piston setup with a larger 11mm diameter piston, and a captive titanium deep carry clip. The assembly is powered by a compact wave spring which provides a smooth firm resistance with a crisp "break" at actuation. The whole switching assembly while a bit more complex in machining terms due to the brass spring cup and acetal isolator around the switch being threaded and slotted, is more consistent and stable in assembly with the switch forming a nice assembly with the isolator and spring plate.


    The head and tailcaps interlock with the body where they mate up to distribute force and enforce consistent rigid lockup.
    The reflector continues to be the excellent McR-16S which provides a punchy beam with a wide spill that makes good use of even moderate output levels.


    Grip-wise I've wanted to try something a little different from my usual "Acme" grip pattern and plan to use what I refer to as a "Wave" grip. This uses a bit wider of a ring with shallower chamfers, the result is a less abrasive grip which still provides a solid tactile grip.

    Well hot damn I cannot wait for this! Any price estimate/ emitter possibilities?

    I know this is very early, still can't help from dreaming though!

    Perhaps the ultimate custom light!

    Looking to keep it the same as the Hyperion, so around $525 USA.
    Emitter wise I stock some R9080 219Bs in SW35-45, 5D XP-L HIs, and SST-20s in 3000-4000K. Could use any 3V XP footprint LED I can get ahold of, but practically speaking emitters with good throw performance like the 3 main ones I stock are ideal for a McR-16S reflector IMO.

    Thanks guys!

    I'm hoping to use calipsoii's newest driver project which is supposed to be AA/14500 capable and programmable. He has documented progress in his FB group Copper and Current Designs. Outside of that, scrapping a production light with a suitable driver is the next most likely option.

    I definitely hope it doesnít have to come down to that. Most likely this wonít be the case, Iím thinking. A lot of progress has been made on the 15vp driver and should be near completion.
    Who needs to see the light at the end of the tunnel when you have friends on CPF?

    I think that would be appropriate, the Corvus is the successor to the Hyperion in my mind, it takes the concepts and improves or fixes all the things that bugged me with the Hyperion. Reduced diameter and length, smoothest piston actuated switch I've done yet, simplified tailcap geometry, easier to service mail seals for the piston, easier to control seal pressure, better supported and more consistent switch/piston assembly, easier switch replacement routine, and a deeper clip arrangement.
    The new seal arrangement also got rid of the "lock-stick" like effect where the x-ring would lock the piston in place in some of the tighter sealed Hyperions and require a firm push to release it.

    A sneak peak at the wizardry of design that calipsoii has employed in his latest driver design. All of this stuff is on a 15mm OD board.

    I havenít purchased a Sigma before, so pardon my ignorance.
    How does the drop/release/reservation process for these lights work? Is it announced here on CPF or elsewhere? I donít have social media, but I may have to sign up to reserve one of these sweet lights

    Thanks sir! These days most sales are in my Facebook group as that is where the most interest is typically. For the Corvus I think the sales in my FB group will be released first-come first serve, and I will keep a reservation list here on CPF for members who don't use FB.

    A mechanical update on the Corvus design. Piston design is holding up very well, minimal wear on the sliding surfaces of the piston setup, with grease still well-retained. Roughly 5 months and at least 2000 piston cycles, sliding surfaces are still polished and greased for an action as smooth as the day it was made.

    Added to the top of thread, please state the LED you would like. I will be using 219Bs in SW35, SW40, or SW45 color temps, and XP-L HIs in 5D tint 4000K color temp.

    Thanks guy, for the moment I will limit the list here to 10 entries. My goal is between this list and my FB group to clear these builds by the end of the year.

    I don't think I have any D200 left, they are all D180 I believe. Added

    calipsoii has done a superb job on the driver, it is constant current 500/900mA high on AA/14500 respectively, 1-4 modes fully programmable with 24 brightness steps, LVP, configurable step-down, switching speed, debounce, memory none/classic/hybrid, and thermal protection.
    It also has an entire separate UI that is fairly easy to switch between (20-29 clicks), a sensibly designed ramping UI for a mechanical switch. Starts at a brightness, depending on memory setup, then a click will ramp up, stopping and starting again will toggle down and so on. Ceiling/floor blink indicators, double tap for moonlight and short-long tap for turbo.
