Mag-2C P7 DSVNI build

[Ajay]

Here is my second Mag build the first was a 2D mag this one is a 2C.
2C form factor is easier to grip IMO.

Parts/mods:

1. Mag 2c black
2. Seoul P7 DSVNI (5350K?) from LiteMania
3. Anodized MagC heatsink from LiteMania
4. 17mm 1000mAh 5-Mode with Mode-Memory Circuit Board for Cree XR-E Emitters (0.9~4.5V Input) from DX
5. Cut down stock reflector
6. Stock switch
7. Cut down spring a few mm, stock sprint too stiff.

Wicked HS color eh?:p

Not my best soldering job and I cut the reflector with a hacksaw!!:thumbsdow

Used some AA NIMH for testing with make shift paper battery holder:ohgeez:

Spring is too large for the AA cells so used a quarter as a washer.


Beamshots to come later....:duh2:


Pros:

• Runs great on Alkaline 2C cells draws 1.5amp at tail and gives about 1.2 at LED. Not sure how since this is supposed to be a 1amp board.

• Can be upgraded in the future for more amps (brightness) easily.:xyxgun:

• Underdriven P7 runs cool, had to use some aluminum foil to make heatsink fit nice and tight in the mag body.

• Nice neutral/warm beam color.

• Circuit capable of running on just one cell...I checked(0.9v)

• Can run on 2 AA cells with a paper battery sleeve in a pinch.

Cons:

• The heatsink pedestal is too long (high) so the mag head must be screwed out far for it to focus for maximum throw. I had to add another o-ring to the head to make turning the head harder....I don't want the head to unscrew too easily over time.

• The circuit board inductor runs really hot and another IC on the board runs pretty hot too. I did test 30 minute run times and the board did not burn out....at least for now:eek:
• Too many modes, 5 in all. High, med, low, strobe & SOS

thanks for sharing! interesting you chose to under-drive the SSC P7... seems like most people go the other way :devil:...

nice light! :thumbsup:

Since your underdriving it, have you considered grinding down the heatsink some to make it shorter?

You don't need all of that if it is running cool anyway.

Also I am not an expert but due to the layering effect that using aluminum foil to fill a space I don't think it will conduct heat well, but I may be wrong. I know aluminum itself is a good conducter of heat , I'm just worried about the layers effect as wadding. I believe this can much reduce efficiency of your heatsink to body connection.
There are products that can do the same job that will be more efficient (thermal paste which you can use under your board as well), but as you said it is running cool anyway at the current you are using so probably no biggy.

Even if its too loose for thermal paste to do the job you might consider putting the paste also between the layers of foil to reduce the insulative properties of layering.

Nice light!.

damn, that pedestal cant be too high are you crazy? you had to cut the reflector WHAT! sorry that is sarcasm, thats the same heatsink i used on my p4 mod and everyone gave me hell about it. looks good.

Yeah the folks at CPF like to go big or go home.:poke:
This build is not for me so I wanted to keep things simple. Good runtimes, brightness and easy to get cells. I hope the C alkalines hold up to the moderately high drain without leaking.
Still should be 300+ lumens right?

Thanks for the comments Databyter. I am not worried about the heatsink temps because the aluminum foil is really tight between the HS and the body. Plus it barely gets warm.
I considered cutting the pedestal yes but that was AFTER I had already cemented the LED on there:ohgeez:

HEHE, yeah I mentioned this to LiteMania, I hope he makes the pedestal shorter on his future heatsinks.:whistle:
