SSC P4 in a Fenix L1P with a Flupic

I've been holding on to a Fenix Flupic for several months now. When I first got it Seouls and Crees weren't even out. My original plan was to pair the Flupic with a UXOJ. But several projects kept me from making it happen. I've been very busy modding light for other people lately so I wanted to do a little project for myself today. :)

Anyway, with the emergence of the Seoul LED the orignal plan for the LuxIII was 86'd. I figured the Seoul would make a great candidate for the mod. So I decided I'd give it a go.

First I removed the stock emitter and driver. No problems here, just de-soldered at took them out. The emitter popped right out after the added heat of removing the wires and leads.

Next with the lower die height of the Seoul I had to make a .030" disc to raise the emitter for proper focus in the reflector. More on the reflector modification in a mintue.. So I turned a .030 disc from aluminum on the lathe. I made it just under the diameter of the pocket in which it now resides. It was anchored in place with Arctic Alumina epoxy.

After the disc was set I installed the Flupic..

Then I AA epoxied the Seoul P4 emitter to the disc being very careful to maintain a layer of epoxy between the slug and aluminum disc. Once the epoxy set I soldered the leads to the board.

On to the reflector. I popped it in the lathe and turned a pocket in the underside to allow the LED to move up into the reflector for proper focus. This made the hole slightly larger but really doesn't matter.

As you can see I got it centered pretty nicely. :)

I have the reflector and LE installed in the head. However the best test I can do at the moment is to hold a 14670 in it and make the - contact with a wire between the battery and body. I've got a 14500 on order from David at the Fenix store so hopefully I can post some beamshots in a couple days.

Depending on what the beam looks like I may experiment with a McR reflector and maybe even make a custom heat sink too.

More to come...

Well done MM :goodjob:

I swapped the Led to an Edixeon with the stock circuit, huge improvement about brightness, besides the ugly tint of these Led's.

Best regards

Well I got the 14500 today. I charged it up and dropped it in. WOW! This is amazing. I'm really digg'in this light.

I will try to take some beamshots later. Unfortunately I didn't take any before shots to compare them to though.

Great job.....I have a Fenix that is all taken apart...Im just waiting for some parts...hopefully I will be successful...

Thanks for the pictures....

I carry my L1P in my coat but now that I have modded two of my lights with SSC P4s, I want to mod my L1P too. Can you give me any advice for getting the pill out of the head? This seems like it will be the hardest part. I have everything else but the flupic. I'm reluctant to run a light that I edc on lithium rechargeables. Am I wrong about this? Are these batteries as safe as Nimh?

Marcus, I just did this yesterday, only the P4 swap part. Heat is the key to getting the light engine out. I used a heat gun, hobby type, and a couple of rubber bands around the head for traction, since it slipped on my leather work gloves, needed to keep from burning my hands. I bought a fresh pair of long needle nose pliers at Sears with nice square tips just for the job of engaging the notches in the back of the LE. I had to find a rythm of getting it hot enough with the heat gun to have it start turning smoothly, but after a half turn, it would cool enough to get sticky. Don't get greedy and force it, go back for more heat and get another half turn. Getting it hotter to turn more is not a good plan either, as you could reach a point where you start melting the insulation from the wires inside. Just back and forth between heat and turning with the pliers worked for me. Takes a while. Anyone got a faster method?

Cooking the head in a Ziploc-bag for about 15min should work too.
Sometimes it will work using a hair dryer. I opened mine without any heat. Only a secure grip, needle nose pliers and force.

Good luck and best regards

I like the rubber band around the head tip.

I've always used a hairdryer to loosen my L1P heads, just undone my final one, (5th one) the rubber band, around the top of the head, just allows enough grip, without being too hot on hands.

One twist and it was done..

Excellent tip.

PS: If anyone needs a L1P to perform the above mod, see...

Thanks to Hondo and Long John for the pointers. I don't relish the thought of damaging the light engine by trying to wrestle with it too much, so I will try to be patient and use a judicious amount of heat. I like the form factor of the L1P so much, I really hope I can get it out without too much trouble. Of course, I don't have a lathe to open the reflector head, so who knows what the beam will look like.

I can't get the engine out of my L1P head, but the L1 opened fine today when I wrapped the head/body in heater hose and used to wrenches. The engine turned right out smoothly without any resistance.
The engine in the L1P turns a few times, then just gets stuck, I don't know from what. I've tryed greasing the threads up with RS's lube and forcing it, but I gouged the circuit a little, and I don't don't think it's worth damaging the light.
I want to put a SSC star in it, but there' no star to swap! I'm not confident enought to mess with removing and installing the emitters, so what now? IS that my only choice, to just change the emitter?

Very nice mod, Mirage_Man. Looking forward to seeing the final pics.

I'm very good at soldering, but I don't have access to a mill or a lathe, so this mod is too much work for me to be worthwhile. Too bad since I have a L1T and SSC P4 just begging to be merged together.

The Loctite in these heads can be a real PITA. Try using the heating method described in several of the above posts.

Any yes only an emitter can be used. Keep in mind you will need to enlarge the hole to allow the larger led to focus properly. IMHO if you can't get the focus right it may not be worth doing the mod.

Good luck!

:lolsign:

Nice mod !

2 questions:
1) How is the heatsinking (at the higher and max levels)
and 2) how does it affect the tint-shift ?

Cheers ! :grin2:

Hey folks.
Solving reflector problem in my Fenix L2P, I installed Khatod 17mm Reflectors from PhotonFanatic. Perfect fit, Very nice light beam. I also replaced stock board with MM Plus, but this is another story. :)

It get's fairly warm on burst if I leave it on more than 5 mins. The other two levels aren't a problem at all. There is some tint shift at the various drive levels but that's to be expected.

Great work!
came very close to doing this one, but don't need to add yet another exotic battery only light to my collection.
