Re: Moddoo Customs: Triple CREE XP-E (reservations open)

This is so cool! 24+ hours of use on low! And a really good 5 1/2 on med! Can't wait to see an XP-G, that will be even better!



:huh:😱oo::bow::bow::bow::bow:

Low mode runtime test update.

It's now been about 30 hours.

Battery is at 3.61V
Current draw is about 60mA

I can still easily read a book from the ceiling bounce illumination.

Re: Moddoo Customs: Triple CREE XP-E (reservations open)

I think I am more excited about the XP-E than I am about the XP-G.
Maybe it's because I don't know how long out the XP-G one will end up being and I need a steady inflow of new stuff.

Re: Moddoo Customs: Triple CREE XP-E (reservations open)

Quick question. I see that you have the switch components for clicky switch lights. Would a twisty light work with this drop in, and still let it change modes, etc?

 

[Linger]

Re: Moddoo Customs: Triple CREE XP-E (reservations open)

yes, just twist off, twist on quickly to change modes. Very simple.

Re: Moddoo Customs: Triple CREE XP-E (reservations open)

I noticed the reservation list in the first post has been updated and that a few people have multiple optic types listed. I remember reading in the first batch thread that there was an option to ship with the optic "loose" and to order additional optics for $8... is that being offered again (I hope?) If so, please update my entry to reflect that I'd like both a narrow clear and a medium frosted optic. :naughty:

Like Sgt. LED, I am really excited about this drop-in! :twothumbs

Yes.

The first batch was built to use glue and so was not tight enough in most applications to not have it. This second batch includes a redesign with closer tolerances with the lens. Having tested enough to be sure, Tom is now building them without glue, permitting lens swaps.

I'm still working to update the OP, but we expect to offer $8 lens options for all future Triples, starting with these.

Woo-hoo! Great news. 🙂

I noticed quite a few people have said they've PayPal'd already; should I do that now, or should I expect to receive a request to pay?

My two-stage, 60 ohm McC2S switch works well with the Moddoo triple XP-E R2 using a 6xAMC7135 driver (~700mA drive current per LED). At full power, I get Vf~3.2V. In low, I get Vf~2.6V and about 10mA drive current per LED.

Thanks JC, it just what i have been looking for!, Do you think you lose too much runtime on low with it?, im not sure if i would buy the 3 mode driver or the single mode, i assume the experience you just shared is with a single mode one?

if i had more money i would buy a single mode XP-E and wait for a 3 mode XP-G that way i could swap the emitter disc to my liking, problem is if i decide to sell one i dont have the means to safely receive payment as paypal (which is what i use) doesnt let my Peruvian account receive money, i can only pay with it.

JC do you have both drivers?, it would be great if you could share your experience with both models, will probably make my decision much easier.

Re: Moddoo Customs: Triple CREE XP-E (reservations open)

Sorry, no data to compare single mode vs 3-mode. I built only single mode drivers for my triples, using two 3xAMC7135 boards wired in parallel. The McC2S low mode should increase run time greatly. I also have a 22 ohm board to get more output for the low mode, if desired (haven't tried it out yet though). Note, if you don't already have the parts to build a McC2S or McE2S, you are out of luck unless you find someone selling the switch on CPFMP. The Shoppe looks to be sold out of McC2S and McE2S switches and kits and no more will be made.

IIRC, the 3-mode has a memory, so whatever mode the light is in when you turn off the power is the mode that the light will start up in the next time. That's not bad. But I'm very picky and even that simple UI isn't quite good enough for my requirements. I need a positive method to verify the mode (e.g., visual or tactile indicator) and an immediate (i.e., non-sequential access) method to get into the right mode ASAP. Hence, I've stuck with single mode drivers.

I don't know what the internal dimensions are for the new heat sink design, but assuming that the driver cavity is the same as for the Version 1.0 heat sink (that's the big question), you could order a 3-mode triple. If you don't like the 3-mode driver, then just build your own single mode driver out of the usual single mode AMC7135 boards from DX or KD. If you don't feel up to building such a sandwich driver, I probably can help you out.

Re: Moddoo Customs: Triple CREE XP-E (reservations open)

Same thoughts about the UI here, i already have a McE2S switch and parts to convert it to a McE2C, i use it with my Malkoff M60 setup, and i love it.

Thing is with this level of output and efficiency i think will be better taken advantage with 3 levels (a lot more versatility), but since the day i used an L1 it spoiled me.

would be great to know the difference in efficiency with the McE2C and the 60Ohm resistor and the low on the 3 mode driver.

JC have you measured the runtime on low with the McE2C?

 

[Justin Case]

Re: Moddoo Customs: Triple CREE XP-E (reservations open)

I haven't measured run time using my 60 ohm McC2S. But if the triple is getting 30mA from the driver, then the tail current draw should also be 30mA. Assuming that my AW17670 cell (the host is a SureFire 6P) really has the advertised 1600mAh capacity, that would give a calculated run time of 53 hours.

I wish I had my OpticsHQ reverse multifunction tailcap to test with my triple. That UI is quite good, except for the small size of the side button. The tailcap also has a relatively high parasitic current drain (about 1mA). That's less of a concern if you have a relatively high capacity cell like an 18650. For a low cap 16340, the parasitic current can drain the cell in about a month.

Edit: I started a run time test using my 60 ohm McC2S on low. At the 2 hr mark, the AW17670 cell has dropped from 4.20V to 4.16V. If we assume that 3.60V is 0% remaining capacity, then linear extrapolation gives a run time of 30 hrs. I'll keep going to see how this initial estimate holds up.

Re: Moddoo Customs: Triple CREE XP-E (reservations open)

Thanks a lot Justin Case for taking time to do this,

The results are what i imagined, a lot of loss from the resistors, and is one of the reasons i favored the 3 mode driver, with it it would be possible to carry it in a 1xIMR16340 configuration, that way i have a great running low-mid for most uses, a bright mid that will be enough for almost all the rest of uses, and a total blast of light for emergencies or when needed that would be used for seconds, or a couple of minutes tops; it would be a very useable pocket rocket.

But even with that i would still miss the 2 stage momentary UI... its a hard decision for me, but im definitely inclining towards the 3 mode.

once again, thanks, runtime tests are not very fun to perform until the final data comes in, i really appreciate it.

Re: Moddoo Customs: Triple CREE XP-E (reservations open)

Yeah, there is an I*R loss. But does it really matter if you still get 30 hrs (or longer) run time on a 17670 cell?

I'm now at 7 hrs and counting. Cell OCV is 4.09V. Extrapolation gives 38 hrs run time, assuming that 3.60V is 0% capacity remaining. That is a semi-arbitrary end point. If I change it to a lower voltage value, I can get a longer calculated run time.

Also, remember that Moddoo is using a 2600mAh 18650 cell in his low mode run time test. I'm using a 1600mAh 17670 cell. Scale the run time by the capacity difference and the current 38 hr estimate becomes 62 hr.

I don't know what situation you envision when you mention emergencies. But one type of emergency might demand max mode immediately, as in right now. Not 1 sec from now. IMO, you just can't get there from here reliably with a sequential access UI. Ever miss a photo or fumble the shot because of your digital camera's shutter delay? You are talking about fractions of a second in those cases.

Completely agree, and thats even if you CAN get to the desired option, because in a moment of stress, or when you are alredy in precarius balance or making strenght with the rest of your body while you do other stuff at the same time, it is very possible to missfire a sequence, or in the hurry, go past the desired mode, i totally agree with you.

you are right about the battery difference, thats a lot of runtime for the output, and that 3.6V bottom you are using is very conservative, if you got the light down to 3V it would be a lot more.

to make matters worse i just saw Electron Guru´s post here and on the hosts thread, he is got that awesome setup for moddoo triples, i wish i had the money for the complete setup, but for now i have this host that i really like to waiting for it, and its compatible with e-series bodies, i can use a 1x123 config or a 2x123/1x17670 one (my Malkoff M60 is keeping it warm), if FM comes back with his e-series 18650 body with clickie i will be all over it in a nanosecond (i wonder if i that clickie can be easily swapped with a McE2S.


btw, i have been misnaming the McC2S as if the name were McE2C, sorry for the confusion.

thanks for keeping the light running so much time JC.
