    Default Fyrstormer's Evil Labs present: Lunasol Centauri

    ...the LunaSol Centauri.









    ...no really, it is special, keep scrolling...









    ...why yes, I did give my LS27 a GDuP brain transplant. The new name is a reference to the Centauri solar system, which is comprised of three stars of varying brightness, much like the three brightness levels my LS-C is now equipped with. Now it's not only a flooder and a thrower in one package, but I can also choose how much throw I want to have. The man behind the curtains is Wayne Yamaguchi, who graciously agreed to accept money in exchange for a pair of custom-programmed GDuP drivers, one of which has replaced my LS27's high-mode driver board. Levels are set to 90mA, 300mA, and 1000mA. I tell you what, this thing is cookin' with gas on the brightest setting.

    IT'S ALIIIVE!!!

    Bravo, Bravo! Did you swap out to cooler Nichias also? Nice work.

    Nice mod! I think you chose the right power pack for it too. They are too finicky with the PD pack I think.

    Well done! I wish I could mod anything.

    No, the emitters are all stock, my camera is just really really really sensitive to the blue spike in LEDs' emission spectrum.

    Ah, so you did build the 4-speed Lunasol you mused about months ago. Never did hear anything back about that one. Well, thanks for the idea.

    I've gotten a couple of requests to mod other people's Lunasols, and rather than copying/pasting the same response, I'll address it here:

    - I can do this GDuP upgrade on LS27s, now that I know what I'm doing, but I'd need to get more driver boards first. I have one on-hand at the moment, basically as an emergency backup in case the one I'm using bites the big one due to some as-yet-undiscovered flaw or soldering error. If anyone wants this done to their LS27, post here so I can get a feel for how much (if any) demand there is.

    - In theory I can also do this GDuP upgrade on LS20s, but I want to mod my LS20 first so if something is slightly different and things go horribly wrong, at least I will not have destroyed someone else's property. I also need to figure out what current levels are appropriate for the LS20, given its reduced heatsink mass, its more efficient emitter, and the lower level of background light coming from its Nichia emitters.

    - Replacing emitters is not something I feel comfortable doing on this light. It's one thing to do an emitter swap on a PD-S, which has easily-removable (and replaceable) parts, but the Lunasols' construction is pretty unique and if (when) I were to put a nice big gouge in a reflector, I wouldn't be able to replace it. I've asked the modding heavyweights around here about working on Lunasols and they've all said it's just too hard and they don't do that work anymore, which pretty much means it's impossible to do at my skill level.

    I've got a moderate level of interest - however I have a coated LS27 and have the clicky pack I believe (I'm not at my apt where my lights are) out for coating and want to see how good a match it is.

    Actually I did LunaSol 27 with GDuP proto back when the LunaSol 27 was in "production" but never went further due to the availability of the GDuP and the consideration that the PD pak made the selection and certainty of Cree level problematic. At the time I wished I had one of the original Clickie paks I had done for the "x2" lights on hand to see how much better it eould presumably behave but I had let them all go...

    I did do a LS20 last year with a 3S converter driving the Dragon and this time I had the clickie pak so I could see how the UI worked and behaved. It works. At the time, the LunaSol series was already "history" and I felt that posting the mod would only open a can of worms for me so put the light on the shelf and moved on...

    So how do the modes work now? Screw the head partway down for the outer leds, and all the way down to cycle through the modes of the Gdup with the clicky?

    Ahhh, a can of McGizmo worms!! I think I'll order some! We now have the option of a warm LED..., the McGizmo worms are loose....

    Yep -- or as I use it, tighten it all the way and cycle through the modes, or loosen the head a bit if I need even, hotspot-less lighting.

    Wow, great work! I was gonna ask a modder to up the drive current on my LS27 but this seems like a better option. I'm interested to hear how much you'd charge for such a swap.

    Edit: I remember Don alluding to a similar mod in the past. I think he called it the LunaSol Eclipse.

    UPDATE: Well, I've been using the LSC27 for a week or so, and it continues to work just fine, though it gets a mite toasty when left alone on the brightest setting for a few minutes. That's not surprising, though, and as long as I'm holding onto it, it doesn't get any warmer than any of my other 1-amp lights. I'm confident at this point that it will hold up to long-term use, at least as long as the highest setting isn't used willy-nilly; and really, there would be little point in having three settings if I were only going to use the brightest one anyway.

    One interesting thing about the GDuP driver I used is the calibration routine runs on each setting separately, and it re-runs whenever the microprocessor detects that the current going to the emitter is out-of-spec -- no need to click the light on/off/on 15 times or whatever the older GDuP driver required. (this happened when I ran the heat test, because of course LEDs lose electrical resistance as they heat up.) I think this is a fantastic idea, and because of it I don't mind at all the occasional flicker that the microprocessor causes to let me know when the calibration routine starts and finishes.

    Also, the reduced-power driver I ordered for my LS20 came in a couple of days ago, and I promptly built an LSC20 with it. Here are the comparison shots:









    Good stuff. And now the LSC20 will be in EDC rotation for a week or so, to make sure it can handle 750mA, though I've noticed no problem thus far.

    Fyrstormer- I see the 750ma. drive level for high, if you don't mind sharing, what are the other two levels? Looks awesome, can't wait for a long term report...

    The LSC27's modes are 90, 300, and 1000mA. The LSC20's modes are 68, 225, and 750mA.

    Am I correct in assuming that you are using R123 Li-Ion batteries to achieve these drive levels?
