I added a search page to the list yesterday but it's too unwieldy so I'm adding filtering options to the table header instead. Suggestions, anyone?

Edit: Done.

Hello all,

I am trying to figure out some options on how to power a light. I am thinking of 5-6 Q3s and I would like to use a 2d mag so 2xD li-ion will probly be my power source. If possible I would like to have 3 modes or so. And I would prefer not to spend a huge amount of money for the driver part of this project (unless I have to).

Thanks

That certainly sounds easier.

You are evil. Don't forget to take photos. :devil:

Sorry, these don't belong here, but you asked for a photo. It worked out great, just need the high power strobes for the eyes next year!

Dual Trumpet Air Horns and wireless remote. I got a few scares!


I love the new search-able LED Driver List. I found exactly the right driver I needed for another project. Too bad the hyperlinks for KD always change, but the search function found them anyway.

Man that site is annoying, and now it seems even when I'm not actually trying to use it or buy stuff from it! But the only non-working KD link I could find was my fault, where I had doubled up on the "http://" in the link.

Anyway, I'm glad the list was some help.

That looks like one formidable pumpkin. I'd be afraid to approach your door if I realised what was in its mouth.

Isn't Rule #1 about the KD site that you can trust almost nothing it says? For example, how big is it? Most AMC7135 boards are 17 mm diameter, but the (probably wrong) information given says it's 30 mm. What are its 5 modes? I can't see anything about that. Why do you want to buy it without knowing what it is? Do you like lucky dips?

You can get five 5 mode 3xAMC7135 boards from DX for $14.55, and know what you'll be getting. (Although I personally think the 16 mode boards are the best because there's a group with no flash or strobe modes.)

Some efficiency results for the 500mA SHO Micropuck driving an XPG R4 from nailbender. I love these things for simple, bulletproof 2 cell Maglite builds.

Code:
     Vin    Iin    Vout    Iout    Eff

      3.000   861   3.106   645   77.6%

      2.900   839   3.095   605   77.0%

      2.800   829   3.086   575   76.4%

      2.700   810   3.075   540   75.9%

      2.600   791   3.064   508   75.7%

      2.500   774   3.054   479   75.6%

      2.350   751   3.037   436   75.0%

      2.200   727   3.020   395   74.6%

      2.000   700   2.995   344   73.6%

      1.750   657   2.961   284   73.1%

      1.500   625   2.922   228   71.1%

      1.000   464   2.798   106   63.9%
Looks like maybe the low Vf of the XPG helps keep Iout higher than 500mA, or else a component in the Micropuck itself isn't properly limiting current to 500mA. Either way, I'll take the extra lumens.

Once I get my 350mA Micropucks from a recent ebay auction win, I'll add that data as well.

Thanks for posting that data. Is the Micropuck in the boost configuration or buck/boost?

I'd go with your first theory, especially if you're trying to boost the battery voltage to drive the LED. I don't think their output is well regulated, and 500 mA is probably just a nominal figure for the sake of calling it something. :shrug:

It's in boost config.

indeed but I ma searching for a 1400mA 5-mode board, or one that has spece to add a 4th chip...

Hey kosPap if you are looking for a buck board to do this you can also just wire in an additional AMC7135 for an additional 330-350 mA. You do not really need the space on the board to accomplish this. I have changed a 2-mode 150mA -1050mA board into a 2-mode 500mA - 1400mA buck board and just last night I added an additional AMC7135 chip to a 3-mode shining beam driver to crank its max output from about 2800mA to 3100mA. It works like a charm. You just have to have a steady hand with your soldering pencil. I got the spare chips from a defective 4xAMC7135 board I had. I also make sure to use AA epoxy to glue the free floating AMC7135 to the heatsink.

indeed! I have seen epople do it with Sandiwch shoppe boards...I think it was dark zero that showed a threesometriple stacking of chips...

Kinda scary though of pulliing it through though

The AMC7135 is a very simple and straightforward driver to play with, and as Fulgeo showed they don't all have to be switched by the mode controller (if you're using one). I don't know why more people haven't done that.

Linear Regulator
ShiningBeam.com SKU:1217
3-Mode Regulated Circuit Board for Cree MC-E and SSC P7 (Not in Stock today, check often)
Based on the AMC7135 X 8 with 3-Mode Low-Med-High with memory

I've had very good luck with this one so far. I remove the preinstalled LED leads and give it some nice 22ga teflon jacket wire to the P7 emitter and I read 2.78A at the emitter from a IMR 26650 cell fully charged. There is a slight ringing in the Mid mode. No problems with heat when run on high.

I grabbed 4 of these, and am using 2 now with no problems. I see they go out of stock all the time, but appear once more come in. Download also has these once in a while in his multisink thread.

I know I've seen more info here somewhere, but didn't see it on the list. Here are some closeup pictures.
