Driver diam is 28 mm. No glue accept a dab under the driver - probably to get the switch aligned to the button, but driver still came out easy. Has a thin brass retaining ring on the driver. Very moddable.
The driver does not act like a buck or boost. Output decreases as the cell drops. My first test was with an LK cell at about 4.05V or so, and got 870 lumens, 188 kcd (2.55A tail). On a full LK cell @4.21V, got 950 lumens, 205 kcd (2.84A tail)
Then made a few mods:
20 AWG bypass wires on both springs
20 AWG LED wires (stock were ~26 AWG)
bypassed sense resistor with a jumper
sanded down centering piece a little
swapped stock XPL HI with a XPL HI V3 2B from MtnE, sanded MCPCB smooth, MX-4 thermal grease
Stock:
stock MCPCB is a good one: 32 mm DTP MaxToch, screwed down by 2 screws - excellent
Reflector I.D. is 61.5 mm - outstanding
Weight: 305g - fairly light for it's size
nice solid shelf
the blue bezel is not SS unfortunately, it's aluminum
the switch looks like a heavy duty one. There's 2 slots next to the rubber switch boot to unscrew the tail - the removable tail/switch housing is plastic though
This got:
1240 lumens at 30 secs, 266 kcd (3.74A)
This is slightly better now than the specs posted. Really needs a FET driver though. Because the switch is driver mounted, I'd probably go with a piggyback driver mount.
Was working on the Clone M3 again. Final revision. It charges!
Specs: Ultimate EDC Light.
MtnE 15mm Fet+1 with D4 v.2 style rampingIOS,
XM-L2 T6 4C on 14mm SinkPad,
ME4056 charger circuit lowered to 550mA
relocated Red LED from ME4056 to the SW board
Green LED always lit except when charging
Hacked a magnetic charge port adapter and mounted where the micro USB used to be.
By far the most complicated mods I have done to a light. Definitely worth ALL the aggravation.
Wasn’t easy stuffing all that into a small light. Used the tiny ME4056 charge board.
Used a completely waterproof magnetic connector, no more Micro USB.
Green LED is lit all the time but green goes out and red turns on while charging. When Charge completes, no LEDs are lit.
Really cool. Do you have more details? I’ve googled the charger circuit, but what magnetic port charger adapter and so on? I’m interested in replicating this in one of my lights.
There aren’t many that use the round end. I suppose the flack given by dumb buyers saying my PC it doesn’t see my phone… It is Charge only.
I searched hard, ask CRX PMs were flying for a couple days.
That one was the best deal for getting 3 connectors to hack up. Depending on the light I guess you could just insert the adapter and seal around it to get same result. I wanted a close fit so I tore into it, removing the connector from the back and soldering wires direct.
There is a company selling Patented “breakaway” connectors for laptops. I think this is making various adapters scarce and expensive. I would like some 5.5mmX2.1mm magnetic power connector adapters.
But doesn’t seem to have affected the phone market for such things. I tried the round to Micro USB on my phone but I could see it causing more stress on the connector in my pocket than using the micro port only. Huge benefit is the super fast and easy connection while driving. But newer connector types that are reversible are already much easier than dealing with micro USB. Hard to say that the 5pin oval types are going to be better or not. Definitely need a flush fit.
The OD on the adapters and wire connector are 8mm, for some perspective.
CRX, are you using GITD powder + resin or the GITD tape on the K03?
Nice one! I’ve been thinking to grab one of these small lights (Sofirn or not). Does it take 18350 batteries?
Thanks in advance! :+1:
