The driver hardware is the same and the default ramp settings are the same between the A1/A2 versions. Newer A2 versions have dynamic PWM to slow down the ramp speed at lower levels but you still need to manually set the ramp floor to level 1.
For anyone wanting to update or modify the firmware on a light they have… read the README file to figure out which flavor to use. It’s not very long. Here’s a copy of what it says:
|How to figure out which .hex file to use
|----------------------------------------
|
|1. Use the version check function to find out which flavor of the
| firmware the light shipped with. It should blink out a date and maybe
| a 4-digit number after the date -- YYYYMMDDNNNN. Write this down.
| Version check is 15 or more clicks from off.
|
|2. Match up the 4-digit NNNN number in the MODELS file.
|
|3. Find the newest firmware for that model. You may need to scroll down
| to reach the newest files.
|
|If the version doesn't include a model number, it's older, but you could
|still look up the model in the PRODUCTS file to see which version it
|probably uses:

The full list is in the MODELS file. Here’s a quick summary of a few…
Regular single-color lights:
0113 emisar-d4v2: D4v2 with a FET+1 driver (DD FET + 350mA linear)
0114 emisar-d4v2-219: Same, but with DD FET power reduced.
0115 emisar-d4v2-nofet: Same, but with DD FET disabled completely.
0133 emisar-d4sv2: D4Sv2 with a FET+3+1 driver (DD FET + 1.05A + 350mA linear)
0134 emisar-d4sv2-219: Same, but with DD FET power reduced
0211 noctigon-kr4: 5A (or 7.5A or 9A) linear channel plus DD FET
0212 noctigon-kr4-nofet: Same, but no DD FET
0213 noctigon-kr4-219: Reduced DD FET power (Nichia 219C)
0214 noctigon-kr4-219b: Reduced DD FET power (Nichia 219B)
Two-color tint-ramping or tint-toggle lights:
0135 emisar-d4sv2-tintramp: D4Sv2 and D4v2 two-color driver with two independent linear channels (9A+9A or 5A+5A or 9A+5A or whatever is appropriate for the LEDs)
0136 emisar-d4sv2-tintramp-fet: Same, but with a DD FET added to channel 1. Not usually necessary.
0215 noctigon-kr4-tintramp: Like the D4/D4S tint-ramp build, but modified for KR4 hardware. Not compatible because switch is on a different pin.
K9.3 is still being sorted out. It currently uses a tint-toggle-only build which uses some weird custom code, so I need to integrate it into the main tint-ramp code for future maintainability.
Tint toggle only:
0261 noctigon-k9.3
0262 noctigon-k9.3-nofet
0263 noctigon-k9.3-219
Tint ramp (can also toggle, but doesn’t have single-channel turbo):
0265 noctigon-k9.3-tintramp-nofet
0266 noctigon-k9.3-tintramp-fet
0267 noctigon-k9.3-tintramp
Those last 3 need to be merged into the 3 before them, instead of having 2 complete sets.
Any plan for stepped tint-ramp? Smooth tint-ramp is interesting, but to more easily reproduce a preferred tint, a stepped tint-ramp mode will be pretty useful too.
Dumb question: is this the same optic used in the manker MC13? I love the beam profile but the output feels weak with the W1 when using outdoors. I’d rather sacrifice some throw for double the lumens, SFT40 would be perfect.
Somewhere between 2mm² and 4mm² is the Goldilocks zone for this sized optic for use as a mid range thrower imo. I swapped a boost HX into my X1L and its a great ‘scanning’ pocket thrower. The loss in throw I would exchange any day for the lumens / beam angle. If the Yinding round 5050 didn’t have terrible tint, that would be the undisputed winner for nearly all throwers between 25 and 50mm bezel. The W1 for me drops out of favor right around 38-40mm, unless an aspheric/fresnel is being used with zero spill.
great info! Thanks for that, as I have been eyeing the X1L for about a month now, wondering how it'd be with a CULPM1 in it. I'm also thinking about putting a CULPM1 in my mc13
