Has anyone already got this flashlight?I can not see any info using provided tracking number.
Mine is on its way, already in Europe, but not in my country.
I got mine (4500K), I’m in USA.
So far it is a great little light. The diffuser is a little annoying to put on, but works very well.
The E21A 4500K is more yellow than the rosey tint on the 219B 4500K, but — upon a very very quick try out — still seems good.
I only ordered one with my preorder. I wish I had taken them up on all three — very happy with it.
Also: soo pretty!
I’d love to see a larger NOV-MU with more LEDs, more thermal mass, and maybe 3x21700 batteries.
3*21700 + ~100*e21A it would be really replacement of photo flash.)
Very beautiful photo, thank you for sharing!
I am looking forward for someone to make detail review of the flashlight.
Nice photos. I’m waiting for mine.
I would love to see the same 21700 tube with a slightly larger head maybe the size of the E07 with 70 or so E21A to achieve 12k plus lumens with even more efficient and brighter regulated levels.
Isn’t cost of 70 emitters going to be very expensive? However I think I prefer something like 32 2000K + 32 5000K E21A with tint ramping, 21700 battery, 6A for each channel, it will be the most ideal flashlight.
Yea it will be expensive but many who want the absolute best will be willing to pay. Double channel would be great but I’m just thinking how difficult it would be for the person flowing the emitters. They will have to be installed in checkerboard fashion for uniform mixing. Seems tedious and high chance for error.
Same but also with tint ramping. I wonder if the code could be modified to push the LEDs harder. 8000 Lumens should be possible with 21 of these. I doubt it’s running in direct drive as the vf is way too low for that. Someone should test for PWM at max output.
Just tried the USB-C charging and I think the body could use some revision here. Many of my cables would only just barely fit in the hole and seemed to not fit snugly. If it were widened by a couple millimeters I think it’d be a lot more compatible.
seconded, I would buy it. I also want higher efficiency driver, copper body too, even if it’s $200.
I like this light, but it gets hot fast, and the light is unfocused enough it’s not useful in outdoors photography without more output.
It really needs more heat sinking and dissipation, along with more output. Something like ROT66, but even bigger with thicker copper body, maybe even a fan!
I measured it (ymmv, I have no lightbox and spectro is old/low end):
(I have no idea what’s with the measurements - I think the duv should be a good bit higher than measured, it looks more neutral than 219b. I was getting errors from spotread for some odd reason, and moving the light/colormunki changed the results a lot, as did the power level. In any case, I think it’s a big improvement over 219b.)
anduril2 ships in muggle mode (max 2300), did you turn on advanced ui?
How did you calculate 8000 lumens?
I calculated the lumen using Nichia’s Esttool spreadsheet assuming NVSLE21A_R9080 sm455 with junction temp 100deg C, optical efficiency loss at 15% (including bezel loss), electrical efficiency loss 10, and 21 emitters running at 1.00A and the resulting output is 5,144 lumens. Now keep in mind if testing with lumen tubes, very floody lights, especially mules, will read a bit lower than actual output because the side spill doesn’t hit the diffuser plate directly and gets wasted. I’ve done much experimenting with the Texas Ace lumen tube and I estimate wide flood lights lose anywhere from 8 to 20 % of actual output.
If we were to use the NVSLE21A_R70 sm455 with the same parameters, it would be making 7,127 lumens. Usually the actual amps that can be achieved in a flash light is a good bit lower than the rated max amps of the battery so assuming 21A current should be a reasonable assumption. Maybe a little conservative but noone’s measured the current in the NOV-MU.
DUV of –0.0077 seems right if you say it is not as rosy as the 219b sw45k. At what mode did you I measured? With the KR4 E21A 4500k mule, I measured a DUV of –0.0125 on turbo and even that didn’t seem as rosy as the sw45k.
highest ramp (2300lm) I think is the one I saved and posted.
The DUV measured lower than my 219b E07. Which makes me wonder if the heat up here hasn’t messed with the colormunki or something.
I measured about –0.014 duv on one of my sw45k running turbo. But on lower modes, it is no where near that rosy
My NOV MU has a flicker on turbo and slight “whine”on turbo with a Samsung 50E cell, but none of that is present with a Samsung 40T cell. Is this due to the 40T being able to supply more amps and the design of the driver in this light?
Mine has a slight flicker on the lowest setting with a 40T. It’s really only visible with the diffuser attached though.
I was wondering, can we hook this up to any USB C charger? There is absolutely no standard, some have up to 18V, I think it might be what killed the port on the Lumintop.
On what lights did you measure 8-20% loss? I’ve never owned a mule myself but I think the NOV-Mu having the LEDs in the centre and close to the glass should minimise the output loss. As for the 8000Lm…I calculated it by using the numbers from TAs test of the emitter but I think his was only 90 cri. I also assumed they won’t be much output loss since it had no optics. What is meant by electrical efficiency loss? Does this still apply in direct drive?
