FireflyLite E12R 12*emitters 15000LM 1x21700 Flashlight

Sense is the word that should not be used here, there are 12LEDs running in direct drive, so going 6V to lose the actual running power of the forecast top lumen output?
You won’t be direct driving 12LEDs from a FET in a 6V output from an actual 4.15V cell after charge.

You can claim if you want a 10A buck driver, that does not mean it is even going to be constant current from a single cell, but you can claim it and it would still be a buck driver even if it not regulated at 10A at all.

I hope the thermal code is optimised so it doesn’t have the small stepdown at 3 seconds, then the main stepdown at 11 like the FW21 pro.

That’s not the norm but you can easily test it out yourself and see. You can’t expect these reviewers to test every single usage possibility out there. You can download the ceiling bounce app if you don’t have any other equipment for testing output and verify it.

A couple years ago I used the MT09R and MT03 as work lights in very large interior spaces and was sorely disappointed how they quickly drop to unusable levels. And no I don’t start it on turbo.

I’m a flood guy who likes 5700K and pretty RBG lights, this light has been sent to me by the Flashlight gods.

I meant its conception

I just successfully placed an order for E12R with Nichia 219B sw45k! I also ordered NOV-Mu with E21A R9050 2000K.

There are more emitter types available now, all of them seem to be in stock:
SST20 6500K 10W CW
SST20 10W 5000K NW
Sumsung LH351D 5700K W2 CRI80 (+$15.00)
Sumsung LH351D 4000K CRI90 (+$15.00)
Nichia 219B SW45k D220 R9080 4500K (+$10.00)
CREE XPL2 HD W2 6500K (+$30.00)

Yeah couldn’t resist the 219B-V1. Thanks for offering that. I really hope there are no first batch quirks like with the E07, I got the sharp edged fins and a mushy switch back then.

What kind of peak current do you guys expect? 36A, 48A?

Must be at least 30A to reach 12k OTF lumen with XP-L2

Should be doable with a Samsung 30T. Even the TM9K can make over 9k OTF with 9 XPL2 using a low current 5,000mah, despite it is built-in with soldered terminals for minimal resistance.

I just ordered a bunch of the newly released Fireflies lights! Can’t wait to test them! :laughing:

Somebody can post photo of the driver? I want to see how programming pins looks like

Can you please tell, do fireflies send you some confirmation, tracking number, etc. Ordered one about 2-3 days ago and still got nothing except PayPal email

Some help?
Wow, things have changed a bit on the flashlight horizon since my last season of hanging out here!
This looks like an well-designed pocket light. I have the E07, and love it.
Could someone give me a BRIEF rundown of pros and cons for the offered emitters? Last time I was on here a lot, the crowd was about evenly divided between the “most possible lumens Cree” folks and the “rosy at all costs Nichia” folks. I’ve never even heard of the Samsung emitters!
So what the pluses and minuses between -
SST20 Group
Samsung group
New Nichia offering
Cree XPL2
??
And sorry for my remedial memory and knowledge!
(in the past, I have leaned towards the higher lumen options, but not the completely ugly end of that spectrum)

SST20 6500K 10W CW

  • the beam “points”/is slightly “throwy” compared to the rest but not compared to reflector light. beam color is not great, CRI is very low, overall lumens good
    SST20 10W 5000K NW
  • the beam “points”/is slightly “throwy” compared to the rest but not compared to reflector light. beam color is not great, CRI is very low, overall lumens good
    Sumsung LH351D 5700K W2 CRI80 (+$15.00)
  • the beam will be floody and make a very round/even beam from edge to edge. beam color is ?? but probably ok since it’s even, CRI is middle of the raod, overall lumens good
    Sumsung LH351D 4000K CRI90 (+$15.00)
  • the beam will be floody and make a very round/even beam from edge to edge. beam color is may be faint lime color indoors on white wall, outside it will be fine, CRI is GOOD, overall lumens good
    Nichia 219B SW45k D220 R9080 4500K (+$10.00)
  • floody beam, fairly even across beam. tint will be pinkish color indoors/white wall but normal outside. CRI is VERY GOOD, output is LOW compared to other options
    CREE XPL2 HD W2 6500K (+$30.00)
  • you couldn’t pay ME $30 to choose this option. It will be very high lumens, low CRI, very floody, probably not very even beam

Thank you, should go and check my PayPal

np. aside from the cool white SST-20’s they are all very floody LEDs (which lets be honest with 12 emitters it’s bound to happen). I would be surprised if they didn’t bring back SST-20 4000K and XP-L HI though

The preorder email they sent me said shipping stock Dec 20-25… where does it say they are shipping now?

The email I got says deliver date 20-25 dec, for that they have to ship now.

Yes but its not clear, delivered to them or customer.

and why call it pre order if they are shipping already

- The XPL2 will make the highest output, my guess is 13k+ lumens with a 30T considering TM9K w/ 9xXPL2 makes over 9k lumens with a low current cell, but will be too blue and Cree has the most tint shift.

- 219b sw45k will have the most pleasant 4500k rosy tint but the most inefficient and lowest output.

-The SST20 4000k should still be the FA3 bin, which have the lowest DUV (rosy) of all SST20 4000K I’ve seen and I’ve seen many. Still nowhere as rosy as the sw45k but better than any SST20 4000K by other flashlight manufacturers.

- SST40 6500k is will have the best throw. However, this is not a throw flashlight but a wide floody light.

- If you want high output and good light quality, the LH351D 5700K 80CRI is a good compromise. I checked with FF and the 5700K is Q2 tint bin, which is essentially afternoon sunlight CCT, or pure white. W2 is the highest flux bin achievable for 80CRI.

- The LH351D 4000k is CRI 90 and T7 tint bin. Don’t know what flux bin. The T7 bin is less green than other LH351D 4000k on the market but still a bit green. It should be a whole lot better than the LH351D 4000k in the E14 III, which I needed a Lee quarter minus green filter to neutralize the green.
