SFT-42R 6500K LEDs are available

My 2 cents: i first bought a D4S sst20 6500k and it did have a noticeable green tint on lower output. Being in love I ordered another D4S Nichia 219C and a D4 sst20 4000K both with uncoated lenses and there’s zero green in the tint. Also I swapped the uncoated lens from my 2nd D4S with the first one (sst20 6500K) and the green is hardly noticeable anymore.

So for absolute power get the sst20 5000/6500K and for cosy warmer light get the Nichia or sst20 3000/4000K. Personally I really adore the sst20 4000K, it was my first none cool white led and it made me go WAAAW out loud:) beautiful colour rendering and easier on the eyes on full power. The Nichia is quite cosy as well, somewhat rosy on lower output. The power difference is really noticeable between the warm and cool white.

Does the sst20 throw more than xpl hi? Surprised the xpl hi only 100 lumens more.

Yes, all SST-20 have higher candela per lumen than XPL-HI.

Only the 70 CRI versions of it (5000 and 6500K) have 4000+ lm output, the 90CRI 3000 and 4000K hit ~3000.

Would love to see a beam shot comparison between all leds and tint options in the same picture against a white wall at about 10 meters and label which tint is each one, that would solve a lot of questions regarding tint and leds.

Thanks!

guessing these will be available thru Mountain in time?

grateful for TK’s review.

If I recall correctly doesn’t latest Anduril have momentary strobes, etc? This will be very FUN light to play with!

Dougiestyle · 2019-06-20T19:16:45.000Z

The video tutorial for all the modes, tweaks and adjustments in this light’s UI would be a Godsend. It would probably be a 45min, 2-part pay-per-view lol. Totally worth it, too!

-Pretty much a muggle with an I Q, uncommon sense and tools. Techno-tarded, mostly, though.

Chatika_vas_Paus · 2019-06-20T20:55:49.000Z

We have Anduril and of course candle mode now.
A diffuser should be made for this. Best would be short as lumintop, not as long as a convoy.

I also need to wait and see what the candle mode looks like on the V2 because im not incredibly fond of the 6/2 build’s behavior.

What would you like to change about it?

Yes, it has momentary strobes. I’m tempted to see if I can reflash the firmware on my camera to enable longer exposures, so I can try some light painting.

Rexlion · 2019-06-21T02:15:19.000Z

TK, for light painting it seems like you could also take more than one exposure and combine them in Photoshop.

I need more time to compare their behavior. I have a few lights with varying iterations of candle mode.

~November 2018 build on a D4S and Q8 - Baseline + looks “smooth”
1st gen D4 (V2 Driver/no fancy lockout) - higher max brightness + distinguishable waveforms of at least 2 triangle waves.
6/2 on FW3A - higher max brightness + distinguishable waveforms of at least 2 triangle waves + seemingly more erratic 3rd wave?

I cant quite tell much difference between the Nov 2018 and D4v1(V2 driver) aside from maybe a minor increase in max allowable brightness fluctuations and the occasional noticeably stepped brightness increases.

Something about the 6/2 build just makes it seem like the “flame” is substantially more active and flickery, and that compounded with the higher allowable brightness isnt relaxing to me. I may have to reflash the older FW3A build just to confirm its the build and not the light, but I distinctly remember it looking different after the flash.

Obviously thats just my opinion though and something minor in the grand scheme of things. Perhaps its all in my head.

HONDARIDER · 2019-06-21T19:26:13.000Z

I went ahead and pulled the trigger one of the D4V2’s. Wont be buying a collection like I did the original D4. Bet I have 20 Emisar lights.

pol77 · 2019-06-21T16:50:27.000Z

Are there going to be other colors? Or a Ti version?

You have a problem Sir

Klayking · 2019-06-21T19:00:57.000Z

Yes, a problem. You seem to think that you won’t end up buying a collection of D4V2s. I hope your wallet has a contingency plan.

HONDARIDER · 2019-06-21T19:28:12.000Z

Contingency plan is to wait till next payday. As far as the Emisar’s go I have one of each color in the D4 with almost all emmiters. Couple of D1S’s and a couple of D1’s. Easy to get a dozen pretty quickly. At $35 each (Except for the D4 with the XP-L Hi’s) that is reasonable on my wallet. Another $15 or so for thV2 just hits a little harder each time, It will be an $70 with the XP-L Hi’s. . I may get 3 or so but It will be difficult to do much more due to cost. Will not happen. Really wish I could find a D4 in Cyan with XP-L Hi’s. If anyone knows anyone with that one in particular.

Is there the Anduril for the new MCU already online?

Ah, okay. I can’t say I’m totally happy with it either. Those changes were mostly tested on the lantern, but I find it looks a bit odd on some other lights. I might have to figure out a way to increase the resolution somehow, like put it on a sub-ramp-level lowpass filter or something. It gets complicated due to having multiple power channels with differently-sized and non-linear steps.

Maybe I could just remove the slowest wave or replace it with something else… not sure. The low resolution makes things look really weird when it’s not actively flickering, but constant movement isn’t ideal either.

Or perhaps I could just increase the resolution, and maybe compress the tables to reduce the size impact. It might only work on bigger MCUs.

In any case, patches are welcome.

…eerrrmm…. Nicotine patches…???

Code patches.

As in other people contributing code aimed at this issue.

pinkpanda3310 · 2019-06-22T13:39:43.000Z

Lol, I have some idea of what a patch is. Was just being facetious

Riku · 2019-06-22T14:56:02.000Z

I am too weak to say no; D4v2 ordered - went with 3000K in sand+ss.

Already have these from Hank’s shop:
2x D4
3x D1
3x D4S
1x D18
2x M43
