New Fireflylite T9R STB90.2 / Osram 1x21700 Thrower Preview

The information I posted above came from an email from them a day earlier. Not sure what hold up is but I’m glad they are testing product to get it right before releasing.

This is the email I got last night, they are shipping the T9R any day now since they have passed testing. The E12R has been delayed another 2 weeks or so but honestly I’m glad they are doing all the testing and making sure when we get the lights they are working properly.

Can someone briefly explain the following:

Why does the Osram LED have that much more throw even though the lumens are significantly less then the SBT90.2?

Because the Osram led is much smaller, and that is why it concentrates the light much more in a single point

a big factor is surface area. OSRAM is 1 mm2, while, say a 5 mm x 5mm LED is 25 mm2, so 25 times the area. Dunno what the size is of an SBT90.2 off hand, but just as example of 5x5, the LED would have to be 25 times more lumens than the OSRAM to have equal surface brightness.

The SBT-90 is a 9mm² die. Luminus nomenclature is straight forward; They put the emitter surface area (multiplied by 10) right in the name. 10, 16, 20, 40, 70, 90, 140 …most are exact figures. I’m not sure how they handle domed emitters ‘apparent area’ though TBH. The reason I mention this is from what I know, the SST20 is a 1.7mm² die. It might be closer to (likely greater than) 2mm² with the dome’s magnification. That’s the only model that I think deviates from its name in exact mm².

ok, thanks, good explanation. Did not know that.

I am anxious to see beam shots of 1.1 and how well it is tuned-in

anyone get one yet???i wanted too see the beam profiles before i resort too the k1…

Nope not yet.

That was my dilemma about a 2 months ago. I couldn’t wait no longer and purchased the k1. But I also purchased this light about 2 weeks ago as well. I’ll report back as soon as I get it

My order shipped yesterday and I just received tracking.

Would the T9R work using an SST20 LED? I think one in 4000K 95CRI would be awesome!

When did you order the flashlight? What led did you choose?

I still waiting for some news about my order on December 13th.

Fireflies T9R single 21700 Thrower

  • Emitter type: Luminous STB90.2

Thanks for your answer. You ordered it 6 days before me. I hope they soon send me mine. In my case, I chose the Osram CULNM1

Cool. I have the slower shipping method, so; it may take a while.

Anybody received one yet… photos?

Look forward to your results!
FF from my examples have been high quality with good value. Hiccups happen.

That would be a nice option to get with the newest FireFlies efficient driver. SST-20 4000K 95CRI is the nicest thrower emitter anyone can get currently (3500K would be also a very good choice).

Also, 3500K is a very good choice for E21A (to be used in NOV-MU).
