I upgraded my ZY-T08 MT-G2 dual switch modded light (Mod/Driver: ZY-T08 series conversion, MT-G2.) with a new custom 1634 based driver with FET and 8 x A705s (instead of 7135s), and a new lighted momentary side switch to replace the old boring black one.
I’ve seen a few lighted momentary switches, but this is the only one I’ve come across where the actual button protrudes the switch casing. I don’t like the ones with the button level to the casing, very unnatural pressing action on those. This one is sweet.
This is one of my work horses down in mines and caves, it usually gets pretty dirty and beat up so I’ll have to see how the new switch holds up. It’s pleasing for the eye though.
Looks real nice Mike C. Love your lighted switch mod.
I’m not sure what the o’ring seal on your battery tube to head is like but I’ve been using C8 bezel orings on mine for a far better seal.
Thanks. It’s an interesting LED. How is the size compared to XM-L2? I have TIR optics that fit XM-L2 perfectly, would these fit without modding the optics?
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.
