Outstanding!
These warm LEDs lend themselves well to full darkness low lumen applications.
iirc you are using Fenix E05 AAA hosts (guessing the lowest mode w 2700k is about 4 lumens)
fwiw the oLight i3s AAA is also a great host. It has a clip that fits on a hat, and a sublumen mode of ~0.02 lumen when modded to 3000k. Very useful, for dark of night bathroom runs.
Must say though, i’m not too thrilled about the 219C 3000K tint.
It’s rather yellow actually, expected more red too, seems like less than R9050.
Maybe it’s just that i miss the extra red in warm tints like 3000K.
But by comparison, i have some Osram Oslon 2700K 95 CRI which do have a lot of red.
It wasn’t specified but those seem to be R9080 and also the tint is more like orange / pink.
(Got some 3500K of them too, but haven’t tested them yet.)
Compared this to the E21 4000K and i get the impression those are rather to the red side of the black locus.
Very nice though.
Yes, oops no, not that kind of porn, it’s that kind of porn.
I haven’t upload any pictures of the E21A sm303 R9080. It’s VERY red compared to those 219C sm303/sm305 R9050. Until the MCPCB arrived I’m not going to test more of these E21A. They’re not the best LED for solder-desolder. The white reflector stuff surrounding the die is too soft. Sometimes the sticky flux residue acts like a hotmelt glue to it.
The first generation Oslon Squares have very good tints, I use a 3500K 80 CRI one in a small EDC and it is very good too. But the output and current handling are way worse than the second and third generation which have too much green in their high CRI versions. Good tint combined with good output and current only gets you to Nichia leds unfortunately.
your words agree with my experience of the sm303, but, I would prefer to see a picture in which you compare your Osram and Nichia side by side in the same beamshot @ daylight white balance, preferably not separately
and thanks for sharing the osram link:
can you show me a photo, since you just completely disagreed with Jerommels comment I quote above
