What did you mod today?

Modded a Jetbeam DDC20.

This is an old 500 lumen XML light that I picked up on clearance. I swapped out the emitter and star for a 4000K XPL HI 5A2 tint. I also swapped the battery tube for an 18350-sized tube from a Jetbeam DDC10.

It’s not the brightest light around and the UI isn’t fantastic. It’s also quite large. Running on a single 18350, the light is bigger than my Zebralight SC63w and DQG Tiny III and IV.

It has one unique and sorta gimmicky (but cool) feature: A 7-segment digital red LED display that shows the mode and battery level. The battery meter seems to work pretty well.

This isn’t as good as the display in the Imalent lights, but on the other hand, the Jetbeam is smaller than the Imalents and the button is easier to use.

Built 6 FET+1 Drivers with A6 firmware, then assembled 3 Convoy S2+ hosts and potted the drivers, assembled 3 more Eagle Eye X6 Triples and again potted the drivers. XP-L V2 3A HI used throughout. A friend rides mountain trails in Cali and his friends have inferior lighting, he says when they lead he can’t see squat! We should be fixing that little problem…

X6 triples are for the bike’s bar, S2+ for the helmet.

6 Lights in a day, got kinda rough on the old back!

The black X2R receives the typical XP-L HI & FET+1 treatment.

15mm FET+1 with bistro FW from RMM: in the charging PCB the first two pin are removed, the second one replaced by 22awg teflon wire and connects to the positive side of the driver, third pin is shortened and soldered to the ( - ) ring. Two extra solder points secures the microUSB connector housing (connected to ground) with the new driver. It is very firmly secured and won’t require potting.

The XP-L HI V1 1A on 16mm noctigon sits perfectly on the shelf. The centering ring is made by Hoop, XP to 7mm size. The new convoy 7mm centering also works but this one is black and looks better.

Now it is much brighter and has better UI. The beam although being tighter is still the floody type, as it seems very difficult to achieve any throw with this small OP reflector, even smaller than the S2+ reflector.

The integrated charging system remains untouched but with a caveat: the light has to be ON for charging. There is nearly no impact on the charge rate if I leave it in moonlight:

On the other hand, it now works as an usb powered light. Drawing up to 1A it provides decent lighting in an emergency situation.

Nice! I’m working on mine right now. Does hoop just sell those or did you custom order?

He already had those designed originally for the S2+ reflector, but they also fit the X2R nicely.

Hey, you should start an X2R mod thread. I was planning to, but you finished your mod before me.

PD I think you should! My mod was too minor for a mod thread, plus you did the teardown first and have the driver project going! Besides I’m not really good at keeping threads updated… :smiley:

finally i reflowed my M43 with Nichia 219C D320 5000K from RMM
(had dedeomed green XP-G2 in it...)

near8k Lumens and a nice tint :)

Made today a Convoy C8 with :
-Fet driver using sir800dp fet , with tk’s biscotti firmware
-Old production xp-g2 S4 2B
-AR glass

Also i did :
-through pcb switch bypass
-modified led centering gasket a little .

And the results … 176kcd !
A great little thrower … or a beast ?!

Nice mod, George. To get 176kcd you must have done everything right, including a well focused led !

Put a XP-L V6 1A into an EE X6. With dome on, I measured 1690 lumens (semi-calibrated ceiling bounce test) and 49.4 Kcd. Dedomed, I measured 1547 lumens and 93.7 Kcd. Significantly brighter than the XPL HI V2 3B at 70 Kcd. All with fresh 30Q at 20-30sec.

I had trouble dedoming this particular XPL V6 1A. I have dedomed 6 others and the dome came off easily after 30-60 minutes of soaking in warm gas. With this one an “outer dome” came off easily but there was a large piece of silicone stuck to the die that would not separate easily. I ended up taking it out of the gas and carefully scraping the silicone off with a blade. Has anyone experienced this behavior with dedoming XPLs?

Fandyfire Warrior got new emitters today. XM-L2 U2 4C 4500K

And the S2+ “Color” triple got a face lift and a magnet


Yes, me, but not with 1A:

Are all your 1A from the same shipment? I ordered new ones and hope I will still be able to dedome them in aceton. I’m not good in scraping at all.

vwpieces, that is a very thorough polishing job you did on the S2+. I never had the patience to take it to that level!

Vwpieces what did you use for the final polish ?

A mod long overdue: replacing the ugly cool white XM-L2 of my copper Olight S1 by a XM-L2 T4 7A led (from Simon’s Aliexpress store). The bezel was removed using the by others described method: first carefully hammer a thin utility knife in the groove, working my way around the bezel, then a thicker pen knife, then a flat drill bit and after that the bezel popped out with a light twist. Thanks X3 and others for working out the method.

Now it has the proper led colour that the copper S1’s are supposed to have:

Finally :smiley:
You did a good choice with that warm tint, that was my first choice for my Ti version !
But after a while, I finally found that it’s too brownish for my taste and swapped it for a 5D1 80+ CRI from IO

EDIT :

For the Ti version, I understand the cooler tint.

(is it flashoholism in an advanced detoriated stage to match the led tint to the flashlight instead of the owner’s preference?)

Thanks,
That was second round. Took pics the first time and it showed all the flaws under light.

This one in Stainless tool a bit longer to get the machine parks out before polishing.

Wet sanded up to 2000 grit and Mothers mag aluminum polish on a paper towel.
