What did you mod today?

Yeah well, I’ve been trying to get the thread title changed to “What did you mod or build today” :smiley:

I know you have your own thread for CRX builds but you ‘could’ start a ’ what did CRX do today ’ thread :laughing: :laughing: :heart_eyes:

Nice colour mod CK :+1:

Some major modifications going on there kawiboy, nice :+1:

That could be interesting… :smiley:

+1, some nice mods going on here.

Nice!
Are XT-E colors different?

Thanks for the suggestions guys.
I ended up swapping the driver with a 12x7135 nanjg, which resulted in 4.35A

I guess you didn’t lose any intensity :slight_smile:
The 2mm² variant has more current capability, mine is fed by a Liitkala 26650 through a TA FET driver.

Nice mods/builds KB. :beer:

Thanks Steve! :beer:

My first mod! I know its baby stuff compared to what most people are doing around here, but it’s my first and I’m proud of it. :slight_smile: Thanks to this thread by NeutralFan Convoy C8 Mod - The WOW Factor I gathered the courage to finally try an LED and Driver swap.

You should be! It’s not the destination that counts, but the journey.
And you just have taken the first step(s).

Swapped the original LED from the Fomolov 18650s for an XP-L HI NW.
I have no hot air station available, so I reflowed with my usual method - PCB placed above a candle's flame.

Thank you! Yes, I’ve gained some much needed confidence too. I’m planning my next mod that will be a Convoy S2+ build for practice before I attempt to mod my Thrunite TN31.

A bit yesterday and a bit today, I modded my old Romisen RC-G2 flashlight, which for me is the mother of pocket throwers. At the time everyone needed to have at least one. It has a really nice and modest size-to-throw ratio and used to come with and XR-E led and its deep light-OP reflector made for a very nice throwy spot.

It received an overhaul now but I did not make pictures of the mod this time :frowning: .

*the tail clicky asembly was replaced by a standard Omten 1288 switch. For that a retaining ring was sawn off an old alu pill that happened to have the same threads. Because I ran out of length (a familiar issue among modders) the switch itself had to be postioned completely inside the switch cover with the switchboard doubling as retaining ring for the switch cover.

*the driver was replaced by a 15mm diameter bistro driver (components of the BG bistro driver were transferred to a 15mm Oshpark board made by Warhawk, except the FET that needed to be the smaller LFPAK33 type)

*the led was a 3000K 90CRI XP-L HI, as sold by Kaidomain, this was the reason for this mod, to check this led out. It is on a 16mm Noctigon board.

*a led gasket was reshaped a bit (top sanded off because it blocked too much light, reamed and bevelled the hole a bit).

*a thin 1mm thick ring was added under the pill as a spacer because the XP-L Hi is thinner than the old XR-E, the pill had to move up towards the reflector a bit.

I first had only the 7135 working and found that the gate of the FET was shorting with the source (=ground) so the FET was always closed. Removed the FET and soldered it back in, now all works.

The beam is nice and throwy, just as expected, with a bit over 500 lumen at highest mode (could be increased with tailspring bypass, but it is ok for a high CRI 14500 light).

Now for the XP-L HI 3000K 90CRI, it is listed at KD for a while now but no one reported on it yet. I hoped of course for a surprise by Cree but it did not turn out to be one. The CRI at lowest levels is 92 with a R9 of 60, not bad, at highest level the CRI is 89.7 with R9 of 50. But alas the tint (of the hotpot) is above the BBL at all levels, and also the perception follows the measurement: compared to my high CRI SST-20 EDC the tint is more yellow/green. Very ok, as many high CRI tints are ok, but it does not make this XPL HI the jewel I hoped it to be.

I think this light will be waiting for a next best throwy high CRI led. I may add a lighted switch as well then.

Isn’t the SST-20 actually throwier than the XP-L HI?

Well, that is according to the D4S SST-20 listing anyway.

I think it is throwier too. I hoped the XPL-HI would be more efficient so if the tint would have been perfect this was a good idea. I may go for the SST-20 as next led in this light but perfect would be a led with 1x1mm die just as the original XR-E.

I have JM70 II, I have 1mm² whitey with no host for it, I wonder what would it do….but probably nothing special.

You modded some tubes into a flashlight. :slight_smile:

I bought a JM70 recently to put a White Flat in it. I couldn’t find any info on a JM70 II. What is the difference?

I just put a Black Flat in a little Utorch UT01, pretty cool, intense little light! :smiley:
