I love flashlights with 2700 Kelvins and I much prefer them to even 3000K, but I want to try a 2000k LED for that vintage orange tint.
The only light I know use 2000k is D4V2 https://intl-outdoor.com/emisar-d4v2-high-power-led-flashlight.html
Where to find 2000K LEDs for modding?
There are some Convoy’s with gt-fc40 2000K. Also, few rechargeable models will probably be released soon.
Edit: if you want just the emitter you can slice a 2700K emitter and get something close to 2000K, like a 219b or lh351d for example.
Simon just dropped some torches and LED's that are 1800k-2000k temp
Maybe Jonathan will comment here. He modded a Thrunite Ti3 V2 for me with a 2700K LH351d and Pebbled TIR. Absolutely love it. It is soooo nice at night and perfect beam (for me). His work is excellent.
Oh yes, the Convoy L6 and S11 has the GT-FC40 in 2000k!
Lots of Convoys, Emisars, and Noctigons with 2000k options.
Yellow and yellow’r
which emitters are easiest and safest to slice?
how is tint affected?
Some are somewhat easy, some have wires on top so it’s almost impossible and there’s also option of using a solvent to get the cap off without slicing. There are also domeless LEDs.
De-doming decreases the output, usually makes the tint warmer(and less green) and the throw better. You might get artifacts in the beam.
It depends on the LED type and size.
The Fireflies PL09MU has E21A 2000k 9080 option.
I have the Fireflies NOV-MU E21A 2000k and I’ve been using it every single night plugged in to USB-C cable as room lighting and I absolutely love it. This is by far the brightest 2000k 95CRI flashlight in existence. However, FF have not been able to procure a certain chip module from the US to make the LUME driver for over a year already so not sure when this will be available again. It was one of the most efficient buck drivers in the flashlight world. The PL09MU is a smaller version but not sure what driver it uses.
AFAIA There is no 9080 2000k* E21A, only 9050.
Lh351d I think.
+1 for lh351d - it’s super easy to slice the dome and you may get –400…–500k cct
lh351 is pretty efficient to compensate too.
can any be fully peeled?
Nichia doesn’t label the 2000k and 9080 but check this out.
9050 means CRI=90 and R9=50
I measured the NOV-MU 2000k using the Sekonic C-800-U and got this.
CCT 1997K
DUV –0.0009
CRI 94.5
R9 96.9
So in reality the E21A 2000k is 9595
thanks, if that is consistent for all 2000k e21a it certainly gives a nice advantage over gt fc40
Is the light similar to public sodium vapor lamps? I’m afraid it might be similar but they have inferior color rendering so I think the LED version might look better and closer to a flame.
Sodium vapor lamps have poor CRI in general, around 20 to 30, no info on R9 (which is not part of CRI rating)
Some are claimed to be 2000K, some 1800K, some 2100K, I;ve seen various claims along the years.
See here some and their specs, mainly very low CRI.
Not at all. Sodium vapor lamps have almost no color rendering, very depressing. The E21A 2000k has terrific color rendering. Colors actually pop out with this ultra high CRI/R9 emitter. In fact, once your eyes are adjusted to the light, it doesn’t even seem very yellow anymore. It just feels like ordinary indoor lighting but a more cozy, kind of like candle light or a lit fire place.
The E21A is pretty consistent. I have a few other 2000k E21A lights modded with Clemence’s / Eurekatronix’s E21A 2000k and they measure about the same.
I will measure the 1800k-2000k GTFC40 once Convoy releases the USB-C versions. This is also a very high CRI emitter but Simon tested the duv to be above the BBL so things will appear yellowish compared to the 2000k E21A. But it is a very easy fix using minus-green LEE filters. I used the minus green LEE filter on my greenish LH351D lights and they actually look great now.
