I have a Wurkkos TD03 with a SFT40 5000K and somehow I like it very much. Not “rosy” not “green” just contrasty and bright. So, what I want to ask the community is; did I get lucky or am I safe to buy another SFT40 5000K flashlight and can expect the same beam CCT and CRI? Is there a “lottery” in this emitter?
I’ve got four lights with 5000K SFT40s and they’re all good.
I’ve not had the bin from Wurkkos, but all my SFT40 5000K’s from Convoy have been consistently neutral - no green, no pink, as you say. From what I understand, this is what the 5000K’s are known for. If you don’t need higher CRI, but don’t care for green, this is the tint you pick.
I too have gotten 2 very good 5000 k sft40 lights from convoy in two different orders. Bright white without the green.
I like neutral to warm tints, but these are very good emitters.
Mine looks rosy in my S8. I woudln’t buy it again.
Does your lens maybe have a purple AR coating?
You could try it without the glass just to check if it’s that.
The SST40 5000K are my new go-to standard LED.
Back in the day it was the XM-L2 4C with 4000K, today I want something more cold, 5000-5700K.
I was researching for that recently (here for example: Purple vs green AR coating comparison). I found out that purple coating means more green in the beam while green coating means less green. I don’t know if that’s the case but i didn’t ask for anything particular from Simon, when i ordered.
Seriously? Why?
Perhaps he doesn’t like rosy tint? It’s not universally loved.
