Picking up another tri-led floody flashlight for hiking in the woods. What’s the difference between Nichia 219C vs LH351D?
I have one in Nichia 219C 4000K and like it a lot. Is it worth checking out the LH351D 4000K? How does that compare?
I don’t have the S12 or any tripples ,
Not sure if that helps but a single LH351D 4000K compared to a single Nichia 219C has more output, and it heats up more as well… It has a better CRI when lighting up foliage or colored object.
You could ask in the Convoy thread, more people will chime in there,
They are pretty similar, LH351D has a little larger die (more flood) and more output. LH351D will probably be 2000-2300 lumens or so. 219C will be lower, more like 1600ish. Not that noticeable in use.
I will say, LH351D in smooth reflector can have some green in the corona, but 219C can as well. Won’t be noticeable in outdoor use regardless.

they have similar CRI Ra and CRI R9, so I dont think there is a good reason to buy the LH351d in terms of color quality.
The LH351d is a larger LED, so a larger hotspot, I dont think that matters in a triple, since the lens creates the beam.
The LH351d is brighter, again I dont think it matters, for general use when not on turbo.

not to me…
the SST-20 has better color quality, higher CRI R9, than both the 219c and LH351d
LH351D is very floody. The beam won’t project as far as SST-20.
For outdoor use the SST-20 is great, with a throwier beam than the other options and better R9. However, the SST-20 tends to look a bit greenish at lower power settings. More so than 219C.
I have all 3 emitters (SST20, Nichia219c and LH351D, all 4k) in my S2+ and I used to have S12 SST20, 4k and LH351D 4k.
If you are going to buy a triple, I found that S12 with LH351D is too floody, perhaps the floodiest light I have ever had (and I like flood). You will lose too much range.
With SST20, S12 produces a good usable beam, but I didn’t like its petal pattern. If I am to choose between S12 or some triple-emitter-under-TIR flashlight, I would go for the latter.
With regards to the emitter, Nichia219C from Convoy is a happy medium between floodiness and range. The led itself is quite rosy, which is lovely. But if you use an ar-coated glass lens from Convoy, it will be greener. The LH351D 4K that I got from Simon is the greenest among the three, but also the brightest. The SST20 is also green under a lower current, and it is not bright enough for me under the same current draw compared to the other 2, but I feel that its colour is the most natural (a bit green, like the sunlight).
