I have the T9R with SBT-90.2 and CULNM1. In my K1 I have the W2.2 CULPM1.TG. The osram T9R put out around 780 lumens, while my K1 puts out 970 with the larger die of the W2.2. Both beams seem comparable in size and throw with a bit less output on the spill of the T9R. I would say it seems to be a good replacement for the K1 because of the built in charging which allows you to use the light while charging. The driver is highly efficient and the body has really good thermal dissipation, not that it seems to generate much heat because of the nice driver. I don’t have the SBT-90.2 in the K1, but in the T9R it does absolutely wonderfully. The current regulation is super spiffy and works very well in all of the new Fireflies lights, it is very efficient and you get pretty low heat output for the large amount of current in these babies, it is a very efficient host and setup.

Thanks for your response.
If you could only have 1 T9R, would you pick the SBT90.2 or the W1? Preference between the two?

I would probably pick the SBT90.2, I think for me it is the better general purpose beam, I love having that extra spill and more loosely defined hotspot, plus it is collimated much closer to the flashlight so the beam is useable at very short distances the W1 has a donut hole 16 inches away. The W1 does also have some minor rings from the reflector, the SBT90.2 doesn’t have this issue.

Is it worth the $50 price premium?

Normally I would say no, but with this driver I do think it is worth the extra $50. 6 amp current regulation really makes the SBT90.2 shine. If you are looking for the longest throw go for the W1, it has a nice tint, not super cool until you go into turbo. But the SBT90.2 fits my needs better and 1800 lumens with current regulation is great and 4000 lumens with the FET.

I see you say the charging work with USB PD, does that mean ‘USB C to USB C’ cable? Do you know if K9.3 also work charging with PD? I read many light need USB A to USB C cable to charge so this is good finding.

Mark_M · January 17, 2021, 9:18pm

It will charge with USB C-USB C and USB A - USB C, so virtually any charger type will work! The K9.3 works well with USB PD and standard USB just like the new Fireflies flashlights. I did look at the drivers in the T9R and NOV-Mu a bit and noticed loneoceans selected a Texas Instruments BQ25616 to handle the USB charging. It looks like this TI controller supports USB OTG with a built in boost converter capable of 1.2A charging, but the flashlights do not support this mode. It looks like maybe pin 6 was left disconnected to the TI chip (but it is hard to tell without pulling out my microscope), I wonder if there is a way to pull the pin high and get it to work… or if there was a reason the feature was left out.

Mark M,

What kind of defects the T9R reflectors, plating discoloration (streaks) or contamination (crap stuck on the plating) ?

They are metal, correct?

Kona_G · January 17, 2021, 8:35pm

Can someone please supply FF Jack email addy?

The FF contact page does not function for me… and I don’t use FB

Thx

Mark_M · January 17, 2021, 8:41pm

One reflector has very minor plating contamination, it looks a bit like paint over spray but VERY minor and not noticeable in the beam (actually my K1 reflector came in worse condition). The other reflector has a minor scratch that looks to be from assembly. There are a few rings in the beam of the Osram W1 and I am not sure if that is coming from the reflector, I think it is though. The rings have a diffraction pattern to them like it is from the reflector not being perfectly smooth. They appear to be metal.

I plan for SBT90 so hopefully rings won’t be an issue

Sounds like a micro texture may have been in order. It’s hard to plate into deep reflector wells like T9R

How do you like UI ?

Kona_G · January 17, 2021, 8:58pm

Thanks for address!

…and for photos. Desert tan is pretty cool color kinda has bronze-ish appearance

Mark_M · January 17, 2021, 8:51pm

The reflector appears smooth but you can see some “stepping” from the machining so I do think better reflectors would help the rings, but the focus is tight and the beam shows it, and that is what matters.

The new version of Anduril is great, a bit of a learning curve for sure and I have the diagram ready to view on my phone, but no complaints.

Kona_G · January 17, 2021, 9:02pm

Got it, machine rings couldn’t polish out smooth

Yeah for sure have Jack send better samples

Ha! Did same on my phone in past

Are there any discount codes for the Fireflies lights?

Mark_M · January 17, 2021, 9:14pm

There was a brief discount for long term buyers, but that is over and there seems to be no intention yet of another discount code. I think these flashlights offer a lot of value for the price without any discount, if you compare say the T9R to the K1.

You must be the first one to receive them! I’m still waiting for my order. Which emitter did you get for the NOV-MU? Measuring 4400 lumens in the TA tube means it is 5500 lumens when compared to the industry wide inflated lumen ratings. Real impressive for a 22350 10A cell and 95+ CRI.

The tube I received was for a 21700 cell, and I put a 40T in mine for testing the NOV-Mu which yes tested 4400 lumens on my TA tube. This thing can put holes in black paper almost instantly, without optics and the LEDs in a tight pattern, it has serious nut burning capabilities. The tint seems comparable to my D4V2/KR4 mules that have the 4500k E21A.

Chicken_Drumstick · January 17, 2021, 11:02pm

Thanks for the info.

Isn’t the T9R the same money or more than the K1 though? Curious but what is the ‘extra’ value?

Mark_M · January 17, 2021, 11:19pm

In my mind it is the ability to charge and use the light at the same time. I like being able to use my light on my night stand and charge it. Also some of the K1’s (SBT90.2) use a linear fet vs constant current buck on the Fireflies. I guess my point is, as the battery voltage starts to drop in the K1, output will drop. In true constant current regulation as battery voltage drops, output should be able to stay constant until the circuit can’t regulate anymore.

thefreeman · January 17, 2021, 11:48pm

With both linear and buck the output will drop once the cell’s voltage approach the forward voltage of the LED, probably sooner for the buck actually since they usually have a higher voltage drop. For the SBT the Vf is low (~2.95V) even at 6A, so it’ll only happen at the very end, same for the E12R, NOV-mu thanks to the high number of LEDs.

Aside from that I got a shipping notice yesterday.

zoulas · January 18, 2021, 10:49am

The NOV-Mu does not seem to have any reflector or optic . How is that supposed tow work?
