WTS: P60 drop-in with XP-G2 R5 3D, programmable

I'll be making some XP-G2 drop-ins for another forum (no, not THAT other forum) and maybe someone here wants one, too.

This starts as a feeler post to find out how many components I need to order. Post if you want one. It'll take a few weeks till I have everything and am ready to ship.

Specs:

LED: Cree XP-G2 R5 3D neutral white (~5000k) (optionally R5 1D cool white 6300K, please specify iff you want that)
Driver: 1.4A NANJG101AK1 with custom firmware (lupodrv)
Voltage: 3V-5V (not full brightness at 3V of course)
Reflector: SMO (OPtionally OP, please specify iff you want that)

I'll also include a small piece of d-c-fix adhesive diffuser film, removable and reusable.

The UI is special, it's highly configurable ('programmable'). You can change any mode, the number of modes, and the memory type (no-memory, normal memory, short-cycle memory). It comes with 5 modes predefined (Moon - Low - Med - High - Strobe), but you can easily delete and add modes.

The price is 25 USD; international shipping is 6 USD.

lupodrv user interface:
Just like normal drivers it has some modes and memory, but it has two additional features:

Mode locking: Select any mode and use it for a second, then quite quickly tap (halfpress) the button 5 times (so it's on for only <0.2s each time), then the mode you started with is locked; it won't change to next mode any more. Good for tacticool or signaling purpose. Return to normal operation by quickly tapping 5 times again.

Programming: You can change any mode to a different brightness, strobe or beacon; you can change the number of modes (1-7), and you can change the memory type (no-memory, classic memory, short-cycle memory).
Select a mode (use for a second) and enter programming mode by 8 rapid taps (<0.2s on each time); then the driver goes through all options (see below), just tap again at the right moment to choose the one you want.
* Programming mode signal, also serves as battery indicator (number of blinks indicates battery voltage)
* Ramps through 16 visually linear levels of brightness up and down two times; just tap to reprogram the above selected mode with that new brightness
* blinks 4 times (* * * *) and repeats that once: strobe (tap to select strobe as new mode)
* blinks 4 times in a bigger interval (*___*___*___*): beacon
* Morse signals "a" (* ---) twice: add a mode; the new mode is inserted before the above selected mode. Tapping here automatically starts programming mode again for that new mode.
* Morse signals "d" (--- * *) twice: delete the selected mode
* Morse signals "n" (--- *) twice: Set to no-memory
* Morse signals "m" (--- ---) twice: Set to normal memory
* Morse signals "s" (* * *) twice: Set to short-cycle memory (see below).
* Then the light exits programming mode without any changes and returns to normal operation, 1st mode.

Short-cycle memory combines the advantages of lights with memory and those with no-memory: Usually with memory you have a few modes, but if you want to go back to the first mode, you have to cycle through the remaining modes. With no memory, you always start at the 1st mode and don't always have to click through all the modes, but you have no memory.
With short-cycle memory, a mode is memorized after 1s, but if you when you change modes again, it will restart in the first mode instead of the next mode, so you don't have to cycle through all the modes. It actually was sixty545's idea. You can have memory, lots of modes, but no need to cycle through all of them. It effectively hides every mode behind all it's predecessors and is very effective if you have your favourite modes in front and blinkies or other rarely used modes at the end.

Very interesting. Thanks for offering.

I’m going to think about this. When do you plan on placing the order?

I’m going to order within the next few days.

I’m on the edge. Can anyone tell me the benifits of p60s? Just seems like I’d be better off with a screw in pill.

They’re just fun to LEGO or at least have the option to do so if you ever feel like it. Plus, you have guys like DrJones making ready to use drop-ins more readily available compared to specific pills.

Even if you don’t improve heat management you’re not going to suffer much drop off or failure if operating at moderate intervals.

How many lumens will moonlight be?

Lowest mode is about 1-2 lm.

Any chances to have it driven harder? 1,4A isn't that much, I'd be much more happy with at least 2A.

The XP-G2 in my LP D-MiniVX is happily driven at 2,5A (was an XM-L driver) without any problem. Bright, throwy, and not overheating. I was really surprised as I was expecting the light to run hotter, but it really runs cooler than the XM-L, just slightly warm.

I don't understand why you would want to drive your XP-G2 that hard considering that the rough equivalent efficacy point between XP-G2 and XM-L is down at about 1.5A, and then the lumens per additional watt reduces significantly for the XP-G2, meaning you could almost get 200lms more when driven at 2.5A using an XM-L T6 die compared to a XP-G2 R4/R5 die.

But heck, what would I know? I'm new. Maybe you want a different throw.

DrJones, I would like one.

Neutral White with an OP reflector.

Any specific way you would like to have the money transferred?

I'm on the fence too, but would want it driven harder (2A to 2.5A). Privably OP too.

Hm, I might try making a harder driven version, I’ll tell you when I have all the components and tried that.

Ramblings: noted :slight_smile: I’ll message you later with my PayPal info.

Any chance of selling the driver only? Thanks

Well I never got that message, haha.

Oh well, that's ok. I'll actually wait for that higher driven one.

eebowler: Yes, I sell drivers, too. —> Custom Driver thread

If you use and LEGO with P60 format lights, You really should get at least the driver.

When you solder it to your desired LED and pill, you have pretty much the mode configuration you have always wished for - in a blink!
After, you can swap the dropin to different style of host, then adapt the modes according to Your use again without having to solder stars / change driver 8)
