What did you mod today?

I know, but i measure the Voltage when open circuit, it’s almost same as Vcc(about 7. Volt), so i guess it will adjust the volt so that current is stable

I have EC4 with XHP70 and stock driver and it works well. You need to use thermal resistor.

I lost the thermal res when reflow the led(damm, that little thing), i dont know the value, so i just solder 10k resistor

So, i reflow the xpl-hi led, change mcpcb to cooper, now it works, so i guess my driver wont work with xhp50 led
I’m sad:(

This is bad news, I want to swap to XHP50.2 too in my EC4…

I dont know will it work, because kiriba said that he modded ec4 with xhp70, and it works, so… i dont know
Maybe difference in Vf


This is maybe my last pic of xhp50.2, before i lost it in my drawer
God, i always love seeing led under UV light

I have the same driver in a Eagle Eye X7 with a XHP50.2, even if it’s on time memory it will start on the same mode if the flashlight is turned on for more than 3 seconds, less than that and it will go to the next mode. Does your driver also have a pre-flash in the low mode ?

Yes, there is a pre-flash on the lowest mode.

Quick Mod on 1508 75mm:

- XHP35HI on16mm copper from Kaidomain

- 1 Mode Buck Driver from DX: http://www.dx.com/de/p/18v-5w-cree-circuit-board-for-flashlights-16-8mm-5-5mm-26110#.WO56sqKJI-U

- Modded with R100 instead of R200 for 2,5A, like wrote on Aqualab: LED Driver List - LED Drivers and Regulator Boards (database driven) (search for “TR-0021b”)

- At tailcap 2,33A

- with 4x 18350er Batteries

At 5m I have measured 372kcd, thats aproximately 1220m distance.

Propably next steps:

- soldering MCPCB to the pill

  • using thicker wires and bridging springs.

I repaired a S2 triple’s LEDs (purchased a prepopulated noctigon and one LED was dim from the getgo).
Replaced them with Nichia 219b-V1 5000k emitters and a BLF a6 driver. Pulling close to 12 amps from an LG D1 at 4.33V. Beautiful smooth beam.

Voltage Meters

I added a removable voltage meter to the magnetic TP4056 Charger unit and potted the components side

.

Also some refinements to the charger tin

.

And a voltage meter on one of my battery drill packs

.

Just finished a Night Piercer mod of an Astrolux SC for a customer. LED swap, driver reprogram, bypassed springs, refocused reflector, upgraded wires, potted driver. Had to re-machine the LED shelf since it was bulged pretty badly in the middle but she’s nice and flat now. Came out at a cool 83Kcd (~575m).

You should post more details of that Eye of Sekhmet light if you haven’t already?
Looks really nice, interesting.

Wow…very nice…it’ll hurt my wallet though :person_facepalming:

I would like to know what led you used … Not the first time i ask , but it seems i may have to ask more times :blush:

Prolly the Super XP-E2 U5 high performance 3 amper de-domed! Been waiting for the smooth reflectors to finish the Jaxman M2!!! :rage: Just a wild guess!

I don’t have any to test … Edit : And they are only available at mtn or mouser :person_facepalming:

Anyone tried them @ 3 amps & dedomed ?

“G” you excited or what? :smiley: :+1:

Haha :innocent:
