Re: Custom built triple CREE XP-E <> P-60 drop-ins. PRE-PAY SALE

It's funny how most everything looks gross when you get REALLY close!:sick2:

The material for the heat sinks is here.

We will cut them tonight.

maybe a few custom deep for MC_E + BoomSS:devil:

Hey! I'm up for the deep heat sinks for an MC-E and a BoomSS.

Good point about the magnification. I put the driver board under a magnifying glass when I snapped the photo. On my screen, the board is 140mm diam. That's a magnification of 8X.

We got about half of the heat sinks cut tonight.

here's a little teaser pic.

I added the 3 circles in a pattern like my clips, and 3 cuts to allow easier optic replacement for you fellow modders out there.:twothumbs


SALE ENDS TOMORROW AT MIDNIGHT

Damn, I'm really excited. I'm really greatful you're taking the time and effort to offer your unique drop-in to the rest of the CPF community. Can't wait to try it out!

If I get mine first I promise to have MrGman test it for us. I will ask him to do the usuall 1~3 minutes w/ readings done every 15 seconds.:twothumbs

Even though the updates and pics take much time, it is greatly appreciated to watch the progress. I applaud you on what I fail to do when I build and wish I later had done 🙂

I am about as excited as the rest of you.
Happy to share the fun🙂

Moddo did you get my PM?

Got it, been working on answers for you today.
Pm on the way my man.

C,
I will send one to G asap.
I will publish the results when I get them.

All of the drop ins will be built at once, so they should all go out at the same time.
Thanks for the offer.

Cool, thank you sir.:thumbsup:

BTW, I have some MC-E and boomSS on the way for testing.
but that's another thread...

Hi,

I already paid, but I wanted to know if I can still pay the extra $40 dollars for"
DOUBLE SOB1100 DRIVERS CAN BE USED TO ALLOW INPUT VOLTAGE OF 3V-16V
ADD $40 FOR THIS OPTION

From testing a P7 P60 by Nailbender at 2.8A at the tail with IMR 18650, the IMR cell sags too much. I was thinking if I upgrade I can use 2 or 3 IMR 18650's, which will allow the cells in series to sag less.:thumbsup:


Please let me know if I can still upgrade and forward another $40 dollars.

Thank you,
bigchelis

Edit: I just realized that in series; all the cells get the same current. So, due to the added voltage of 2 or 3 cells what is the current with 2 and 3 cells (I expect 1.5A or less)? If you don't know yet what do you expect it to be?

I am no electronics expert.
another member may be able to help you more with those calculations.

I can build it how you like it. Let me know.

Thank You sir,
there is no such thing as an R2 7A warm available.
please specify the R2 emitters or the Warm emitters.

Moddoo,

Please build mine with the 2 or 3 li-on option for $40 dollars more. I will forward the extra money shortly.:thumbsup:

For 3 Cree R2s in parallel for the load, 3x18650s in series for the power source, and a 2xSOB1100 sandwich for the driver:

- Assume 80% driver efficiency
- Assume Vbatt under load of 3*3.7V = 11.1V
- Assume forward current of 2200mA/3 = 733mA per R2
- Assume R2 Vf=3.4V @ 733mA forward current

0.80 * 11.1V * Ibatt ~ 7.5W

Thus, Ibatt ~ 0.8A.

For 2x18650s in series, Ibatt ~ 1.3A.

If your cells can hold a higher voltage under load and-or the driver has greater efficiency, then Ibatt will be lower than these figures.

Good stuff.
If I use 2 IMR 18650's it could be around 1.3A at the tail.

If I use 3 IMR 18650's it could be up to .8A at the tail.

I definitely; will be running mine with only 2 IMR 18650 cells. The current would be so low that the IMR 18650 should have minimal sag and I would get optimun out the front lumens (hopefully).

Hi,


Just sent $40 dollars more to get the driver that allows me to use 2 or 3 li-in cells😀


Thanks,
