I swapped the emitter in my D4 few weeks ago for the KD 4000K ones, and today I decided to slice the domes for a little more throw :
Before and after :
As expected, the throw is improved and the tint has changed for a more rosy beam, nothing bad at all 
Unfortunately, the beam is now more square-ish, as in the XP-L HI version I would guess.
Made a metal switch for the Noctigon M43
And did the D4 too
With 2 LEDs in diagonale, when seing this some people with OCD are going to be pissed. 
That is the way they are set out with the three different colours, just more noticeable now, but you’re right, I prefer it when the green ones are lit 
This is the third iteration of this mod
I’d wish i had your skills and creativity.
Thanks mate, but I wasn’t born with them, it’s more of a perseverance thing
Got a Jaxman X1S XHP35 HI C4
Stock was pulling 1050lm and 110.000cd
swapped the emiter with a XHP35 E2 3C and added a R100 resistor to the driver
now it blasts 1650lm and 181.000cd.
It’s surprising how good is this flashlight with two inexpensive mods.
Did my very first de-dome.
As it was my very first time doing this. I first tested the method on my “beater” light, an old “UltraFire XML-L2 U2 800lm 7000K”.
Got the sinkpad out, and left it in a sealed container with gasoline over night.
12 hours later the dome came off with no force at all, in one big piece. That was surprisingly easy
Throw is better, more focused beam, and the color is warmer. But i do have to get used to the green’ish tint it has now.
I did a similar thing, putting Nichia 219C (4000K, 90+ CRI) LEDs into a Vollsion SP11-S and Fenix E99Ti.
Left to right in these pictures: Vollsion SP11-S, Fenix E99Ti, BLF-348. Before and after.
I have a Solarforce L2P with an M3 head on it, modified it several years ago with a de-domed XM-L2 and Wights Rev 1 MOSFET driver, it had the big Vishay 07N02 on it. Already had a McClicky switch from the previous mod session.
Set out today to bring it up to date with an SST-40 emitter. Went fine til I put a fresh charged Sony VTC5A in it, at a bit over 9.7A the emitter balked, it’d light and show 5 modes but was very dim. So. I took it back apart and went a different direction using LED4Power’s LD2 driver and a new XM-L2 U4 1A emitter. Making a nice beam, pulling 4A at the tail on a VTC5 for 1090.2 lumens. Moon or the lowest setting is 4.5195 lumens, with a 61.41 lumen Low and 522.33 lumen High. I didn’t do any spring bypasses, figured to leave it in an eco mode set so it lasts longer. 
The SST40 showed me about 1600 lumens before it quit, using a VTC4 down to 3.78V.
Still, this old light now has a new modern driver and emitter, pretty nice light even by today’s standards. Seemed odd, going back to a P-60 style light. This one has a bigger reflector screwed onto the brass pill, but still. Oh well, it was something to do for a little while anyway. lol
I modded the moon today.
Well, maybe not *the* moon, but moon levels, at least.
I added dynamic CPU underclocking and some idle modes to make low levels more efficient. The result is that moon mode runtime went up by about 3X or 4X.
Love the warm colors :heart_eyes:
l42dk, I need some of your gas! That’s a VERY clean de-dome! Nice work!
I change the led of my manker e14 to xp-e2 to amber red, change the driver to amc7135*8 for safety
Now it looks very “red” and quite scary to me 
(The wire on TIR is temporary, i removed it)
ehm, my E14 has 4 leds 
USB rechargeable Emisar D4 with red locator light
Edit:
The heatshrink was keeping in too much heat so I removed it and tidied the tail up a bit
thumbs up for u CRX :+1:
oops, i forgot to say i also change the mcpcb to fit the tir len, bought from kaidomain
I’ve been reading this and similar threads on here on a regular basis for the last year, but have not got involved despite doing lots of little projects and mods myself.
So to start off, I’d like to mention my recent DQG Tiny 18650 mod, which I documented here:
