What did you mod today?

I will cut you some slack. In 17 years your retirement will be an extra 3 years away.

Had that covered, I’m 51 now :party:

Such a shame :stuck_out_tongue: Both my mh20 and my mh20gt is glued . These are my favourite stock lights , modding them would complete the deal …

What do you want to do with those lights? Now you got my attention.

Got the TA driver for MF-01 from Lexel last night. WOW!



Worked on the UT02 6500K today.
20AWG wires and bypassed springs. R100 resistor mod and polished the SW cover after it got scratched taking it apart. SW also wasn’t very smooth but it is now.
Impressive light for $30. I liked seeing the Genuine TP5000 chip on the charge board. Nicely made over all too. Killer pencil beam and I am pretty happy with what they call 6500K, no blue IMO. I got 3.78A at the tail on DMM.

Zero back feed to the charge port so I am going to integrate a magnetic port adapter like my M3 Clone.


Mh20 : emitter swap to dedomed sst-40 , or xp-g2 dedomed if i can resistor mod the driver .

Mh20gt : emitter swap to xp-l hi nw and resistor mod if possible .

The EC21 that I got open yesterday, tonight has received a Nichia 219C R9050 sm4070e led. The output did not even really suffer from it, measured at 30 seconds, the output went from 445 lumen to 375 lumen. So just a 15% loss for a dramatic tint and colour rendering improvement. (But the EC21 was never about output anyway, but about usefulness and runtime).

This is my first mod with this exclusive led (just a handful 219C’s in this specific tint area were obtained and sold by clemence) and it is different than I expected. I expected a quite rosy tint on top of the slight yellow-ness that 4000K leds have, instead it is less yellow than my 4000K R9080 E2L mod, and not rosy at all, it looks very neutral white to me.

(it may be this particular led, the sm4070e tint covers a fairly large area , although it is all under the BBL, but this led may just be close to it)

All in all, a super nice neutral tint :slight_smile:


( ^ this pic suggests a load of red but the camera did not pick up the real tint very well. Btw, even the camera sees absolutely no PWM)

Got the New Convoy S9 today.
Just had to take it apart. Didn’t even turn it on before hand.
Aluminum MCPCB so it got an XM Noctigon. And had cheesy wires that melted while desoldering so it got 22AWG silicone from the scrap pile.
I measured 1.9A at the tail, higher than rated.

Here is a pic of the driver. Could it be resistor modded?

Very nice polished the SW cover.

May i ask where did you get the polished the SW cover ? i need to make mine look sexy too

That SW cover had a nasty coating on it. Not just the Anno. Stripped the anno in Lye. Tried sanding it with 400 and gave up. Started lightly filing it down to raw metal and continued sanding getting up to 2000 grit. Used Mothers aluminum polish on a paper towel.

Originally the button had a nasty chrunch while pushing and felt bad. Its nice and smooth now.

the 0R050 resistor may be the current limiter, making it smaller increases output
not sure depending on board layout it may be for the charge circuit

Yeah I was thinking that but I do not know enough. It is 0805 size and the pads and easily do 1206. I had not measured it before taking apart so I didn’t want to add another before knowing. I have some 1206 R050 on the way and have 1206 R100 on hand. Will wait for the other R050 to arrive for easier stack.

Didn’t separate the boards either. Will try on the next go and get some pics. I kinda think all charge is below.

Looks like the S9 was in a giving mood.
Put an R100 on top of the R050 and I get 2.7A at the tail on my DMM.
At 2.7A the light now get s hot with the Noctigon MCPCB. No step down. Holding it in bare hand seems to sink enough heat but standing alone it will get hot and the heat will travel down the tube heating the battery.

It appears to me the charge is all on the lower board with the E-SW.
I separated the two and there is another pair of indicator LEDs under the top driver board that turn on blue with light and the second red LED shows low voltage.
The three pins are, Pin closest to SW (Left) is the SW signal, Middle is Pos and the Right would be Neg.
With the boards separated and a 5V power to the micro USB the blue lights and there is a faint flash of the red as it hunts for something to charge.

Best I can explain it….

Lower Charge board

Top driver board and resistor mod. Also Bottom of the driver board with indicator pair of LEDs.

All my gear is put up for family visiting during Christmas, but I still managed to fit an UCLp lens to a new Red Sofirn SP10B with side switch. Very neat little 14500 light with 4 modes, gained 68 lumens for a simple lens fitment. Took it from 590 lumens to 659. :smiley:

Amazon delivered it overnight, on Sunday, even Christmas Eve! Sweet work on Amazon’s part and whoever delivered it…. :+1:

Sofirn is doing some excellent work these days, loving their offerings…

Will be doing a review on their new SP32A tomorrow… (big brother to this little 14500 light)

Had time for a wee cracker mod before starting the Christmas dinner today :slight_smile:
Yeah, we just don’t stop :smiley:

The DQG Hobi ti dual, with an XP-L HI emitter on one end and an Amber XP-E2 on the other, powered by two 10250 MBI Nukes. Thanks to kiriba-ru for the optics :beer:

CRX is just incredible guy…

Merry Christmas to whole BLF!

I dimmed down my Q8 side button leds by swapping resistors from 33k to a 100k. I only had 0805 size resistors to play with, so I had myself a challenge :person_facepalming:

But all ended well!

Looks good zipelgas. Solder can be very flexible when you need it to be.

The little Sofirn SP10B was making 590 lumens on a 14500 Li-ion cell, really quite good. And 270 lumens on an NiMH AA. I got some new XP-L2’s in today and wanted to see what the tint is, so I put one in this small light. :slight_smile:

Now the NiMH makes 496 lumens and the 14500 does 1070 lumens, pretty much doubling output across the board (Turbo, anyway) Tail amperage shows 2.10A on the little light. Pretty neat getting 1,000 lumens from a small 14500 side clicky light! :smiley:

By the way, it’s big brother (SP32A) also a side clicky, makes almost 1900 lumens from it’s factory XP-L2. :wink:
