Xhp70.2 and xhp50.2 (3v version) 5000k bins are my favorite. You won’t get higher output from a 5050 size emitter than the xhp50.2. Really like the sst40 though too… crazy lumens out of a single die and low vf. I like crazy output more then CRI I suppose.
I could not agree more, right down to the 4C. In the 3535 package, I still really like the Nichia 219b, yes B. The output is not high, but the light is a super high quality. If we get down and dirty the the SW45k and the 3500k variants are my favorites.
The MT-G2 is a wonderful led, so smooth and as stated above very creamy output. The SST-20 FD2’s are also pretty good, but they really want to be a thrower led and need the right reflector or good optics to perform well. I do love the LH351D in 3500k also.
The 4Cs are an interesting bunch. My first S2+ with a 4C in a reflector was kinda horrible. On first sight I was like, “No way that’s a 4C, as that’s way too yellow”, but when doing ceiling-bounce, it was quite nice.
Awful angular tint-shift made the hotspot overly yellow and the spill overly blue, the classic fried-egg beam.
But behind a TIR lens, mixing those colors pretty nicely, it’s a great beam.
Pretty sure they were all XM-L2s, as XM-Ls would’ve been pretty old by then.
And I suspect anything warmer would be the same, more phosphor implying more tint-shift.
Best overall LED in my experience would be Nichia 219C CRI90 3500K and higher CCT, especially 4000K because it’s such a neutral CCT i.m.o, but 3500 is actually nicer. The 5000K is very nice too.
I’m not sure why i prefer them over 219B V1 though, but i do, somehow…
Already started on the second 100 pack, I have more on the way and also some of the 2300K to try.
They come out to about 16 cents a piece delivered at quantity 100 and I have found all kinds of use to turn craptastic 5mm LED lights wonderful. It doesn’t cost much to spread a little hi CRI goodness 10 lumens at a time. A 60 degree floody beam, warm white, tolerant being over driven. Most recent was some old useless solar path lights I found in the garage.
Forgot whose review, maybe The Flasholic’s, showed a light with a 70.2 in an outdoors setting, and the tint-shift was still very visible. :confounded:
I’d think it is a lottery thing. That, and cameras don’t show what exactly what you’d see in person. Even on a white wall my sc700d doesn’t look bad, just a tad green. Mine is 5000k though and I am guessing he got a warmer option.
Controversial opinion, but I think I’d actually rather have a tinge of green or yellow than a purplish beam. ZeroAir loves his BLF-348 with the purple beam and compares everything else to that. I don’t really understand. I prefer to have lighting that mimics light found commonly in nature. In his latest review he compares two beams and dislikes the 70.2 emitter for being yellow. Personally I think the purple is distracting in a bad way. On low levels the 70.2 he shows (4000k) has a brownish halo that I can understand might bother people. But on high levels i think it looks better than the purple BLF-348
my favorites are the two 219b on the left:
sw30, sw45k, not the Neutral Green xml2
I like the warmth and color rendering of the sw30, especially at night
I like the neutral white and color rendering of the sw45k, especially during the day
