Browsing the website today and it looks like there are some pleasant updates. All of the M61N lights appear to be the SST-20 4000k 95 CRI and the M61W variants are all the 3000k 95 CRI option. I was always very happy with the tint and apparent CRI of his neutral and warm XPG2 LEDs but this is just fantastic. Who wants to buy all my old Malkoffs now so I can update lol

Looks like the M91B and M31 lines haven't changed to the SST-20, though.

Nice, just ordered two M61W's!! Now I have to figure out what to put them in, chance to buy a couple new hosts.

Ughhh.....killing me with 3000k and 95 CRI. I had to pass on the sst-20 m61w when I saw the neutral hound dog xp-l in stock. I am curious to see some shots of the sst20 m61w vs the previous m61w. I'm almost happy it's out of stock already to prevent the temptation.

Same here! I'm actually happy though because I'd have to pay an extra 60 USD to have it shipped to my country.

Amp draw as tested through the tailcap? If so, I am seeing 1-1.2A on 1x18650 and ~0.95A on 2xCR123a. M61 SST-20 using a Fluke 115.

Any beam comparisons with old xpg2 especially in neutral? Thanks, still sitting on the fence on this latest offering. Wondering if next aa lights will also have new emitter.

That’s spot on with what I’m getting with the last version M61. Good to know. Thanks.

If he reads the same way I do it starts at 1A and when you wait it will creep up some. Think that’s normal

Should have them tomorrow! I'll be able to compare each SST-20 to 2 M61Ns, 1 M61W, and 1 M61 cool. Just gotta get them all lined up!

Ok, thank you. Does the current go up because the voltage of the cell actually sags a little? I assume it does not get any brighter.

Since the M61 uses a buck circuit, current will continue to rise as the battery's voltage drops *while the battery's voltage under load is high enough for the light to keep running in regulation*('cause that's what regulation is).

Thanks. I read it as going from 1 A to 1,2 A in a matter of minutes (because of voltage sag under load), I guess that's not the case because the voltage would be dropping from 4 V to 3,33 V while maintaining same output which sounds too much for a current draw of only 1 A. I might be mistaken though and I'm not very knowledgeable on how much the voltage actually sags under load!

Link to IMGUR Gallery of comparison between all current SST-20 M61s, and the older XP-G2 equivalents.

Not the best shots, these were just quick. Overall, very very excellent replacement. The hotspot is slightly tighter and brighter, but the diffused mid-section is slightly more filled in, oddly. All same exposure settings, white balance at 5050K (for some reason my S8 won't go to 5000K exactly). Host used was a 9P with 2x17500s. Just hot-swapped the modules.

Tint on all of my SST examples are exemplary. The 5700K perhaps has a touch of green, but the SST-20 4000K and 3000K are superb, both are slightly rosy, perfect for their K temps.

Will try to get better beamshots when I have a little more time! The upgrade is 100% worth it. I even notice slightly higher output on the 3000K modules with the SST-20, but I haven't taken any official readings. Might be able to get to that this weekend, we will see!

Awesome, thank you dot for the pictures! Still trying to decide on M61N or M61NL, but I'm going for 4000K for sure.
