FREEME ✌ ASTROLUX EA01 SST40 (2300lm)/ XHP50.2 (3500lm) TIR 26650/ 26350 Flashlight Group Buy - ALIVE!

I would like to ask a question to the owners of Astrolux EA01 (or Mateminco MT01), who have a blue flashlight. I see that the TIR optics are transparent and have the ability to see anodizing from the inside of the head. Does this affect the light? Perhaps it was from these considerations that I ordered myself a gray one … It seems to me that some spectrum drift into a colder one is possible. Interesting in the SST-40 5000K version…

I just got in a blue EA01 XHP50.2 5700K, already had a grey MT01 SST-40 5000K. I don't think the color of the anodizing effects the beam/tint, but someone who better understands the optics would know better. The blue shell sure looks blue. I got a FT03 in blue and think they match up pretty well. I do know they use something like plumbers putty to cover up the switch hole and it's wires - not sure what that's about, but it's in both my EA01 and MT01.

Are there any differences besides the LED and the inscriptions on the case? :slight_smile:

No. There were some QC issues with the EA01:

  • SS head had some sharp edges, actually burrs - used a rounded file to file them down, all good now. Probably would have torn up a pocket pretty good.
  • noticeable fibers and specks in the optics. Not sure where, either on the optic or MCPCB or both
  • some small amounts of what appears to be a clear glue on the outside of the tailcap. Didn't remove them yet, but not a significant issue.

Noe of those issues, or anything else noticeable was with the MT01, though it's probably just luck of the draw, doubt it's because one is Mateminco and the other Astrolux.

Благодарить. Потенциально с облегчением, потому что ко мне едет именно MT01 … :+1:

Thanks Freeme. My EA01 50.2 arrived yesterday and I couldn’t be more pleased with it. Took about 3 weeks. Does anyone see a violet colored center dot when white wall hunting from about 10 feet away?

I don’t see that in my xhp50

Huh. I only see it inside so no biggie. Was just wondering. I have been using mine at top of ramp mostly (default). 5500 Shockli goes down fast at that setting. Care to guess what lumen level 120/150 is? I don’t think you can just multiply .8 x 3500 to get a ball park and I don’t have any way to measure lumens.

That’s funny, bc I would just multiply (.8) x 3500l, it makes sense to me but I know with the driver it probably doesn’t work like that like you said.

I may be wrong but I thought I remember TK saying something to the effect that it is not the case.

Gray tube is apparently tight for some 26650.

Well, these are indexes in to the ramping table. The ramping table is logarithmic, not linear. So, 120 of 150 is programmed at about 1/2 the max amps (I think, at least from memory). So I believe in theory, you should be at about 50% of max lumens. PWM'ing a FET at 50 % (I think) results in about 50% lumens.

We use TK's Python script to generate the ramping table data that does the logarithmic conversion of basically amps to perceived human eye brightness. The poor examples we've seen of ramping, where it seems to take forever and changes fast at low settings and super slow at high settings are ones that do straight linear ramping.

I have my doubts about this. Even neglecting the technical absurdity of this, the 21700 adapter simply won’t fit into a narrower tube. Judging by the video, where it fits tightly into the blue one.

Thanks Tom, great help. Is the ratio the same for other ramp levels? ex: 4/5 ramp = 50% lumens, 2/5 ramp = 25% lumens, etc.?

Don't think so. Here's an example of ramping tables from NarsilM for a FET+1 config:

//---------------------------------------------------------------------
// Standard FET+1 2 channel modes
//---------------------------------------------------------------------
//#define RAMP_SIZE 130 // for using TURBO_LEVEL_SUPPORT
#define RAMP_SIZE 150
#define FET_START_LVL 66

#define TIMED_STEPDOWN_MIN 115 // min level in ramping the timed stepdown will engage,
// level 115 = 110 PWM, this is ~43% (for 350's)
#define TIMED_STEPDOWN_SET 102 // the level timed stepdown will set,
// level 102 = 72 PWM, this is ~32% (for 350's)

// For FET+1: FET and one 350 mA 7135 (tested/verified to be smooth):
// level_calc.py 2 150 7135 3 0.3 150 FET 1 1 1500

level_calc.py noted above is the Python script. The values in the tables are the PWM values, and the index into the tables is the ramping level. When we ramp up, the index gets bumped up by 1 every 16 msecs.

UPDATE: to my original response - i do in fact see the violet dot. I actually did not at first, because it is very slight. but i reflowed a xhp50.2 6.5k in my noctigon KR1 tonight and i saw the violet dot. i’ve never seen this before with any of my xhp50 single emitter lights, but now going back and checking i see it in multiple of my xhp50 lights. i am actually kind’ve bummed, as ignorance was bliss - before when i wasn’t looking for it i never noticed it. My kr1’s xhp50 came from Simon’s convoy store, so its in my astrolux and convoy lights.

Also, i see it outside, from 100 feet away while shining it on the side of my house (more so in my 6500k light then my EA01 5700k light).

but i just wanted to let you know, you aren’t alone with this stupid purple dot. Anyone know what it is? Or why? My KR1 has it, even while running in the “5amp CC” levels. not just turbo.

Surprised no one else has chimed in about that. ^

so on Aliexpress is the quad version not available anymore….:cry:

Me too.

You should have already shown what it is about …
