I took it as 10,000 lumens, with high quality “Sumsung” LEDs. I am just joking, I certainly can’t speak two languages so what do I know of phonetics and honestly Jack can write English better than I can usually. I am thrilled with the new models and can’t wait to test them all out, I have a few of each model coming since they are a combination of high CRI, awesome bins, and USB-C, an award winning combination in my mind.
LH351D 5700k anybody have experience with…, is tint more or less greenish on lower levels like 4000k?
Jack is more than likely educated at Harvard
From Jack: Firefies pogo programmer key will be available soon, This pogo key is compatible with USBASP, and only supports to reflash drivers on new fireflies flashlights. It supports common USBASP and 10-Pin cable.
Hank has had issues with this as well, and more recently. I have a D4V2 with E21A emitters that can crush almost any size 18650 unprotected cell because he used a brass button in combination with a spring on the positive battery terminal. I am not sure how many were sent out that way, but Hank has tons of experience and sometimes mistakes just happen. At least with Hank or Jack if you have an issue they will either repair it or offer/sell you parts to fix it yourself. Some companies like Astrolux won’t sell you individual parts like drivers or honor any warranty, leaving it up to you to source parts or throw it in the trash, and that is unacceptable. Jack has always helped me buy replacement parts, and his customer service always has been reasonable.
It’s getting very close to the 20th. Is the shipping of the lights still on track to be shipped then? Please give us an update.
I doubt it will be this year.
Have they sent the T9R to anyone buyed it?
Nope not yet.
They are testing the first batch and should start shipping in a few days. Possibly this week.
Still waiting for T9R, no news from FF about an upcoming shipment.
I`ve seen in the thread of another FF model, that they are going to start sending them, but without a specific date, and I have not received any mail from FF.
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.
