Because of a thread on a different forum I decided to measure the CRI on my phone, because someone said that "phone lights are high CRI" and I was like there is no way that's true. Well it's not, mine has a R8525 4500K LED, but that's not my current point.
So while I had the spectrometer out, I remembered I still have my first ever "serious" flashlight, an Olight S30R, which was - at the time at least - like magic to me, the power, the compactness, the machining, the different modes, I loved it. It was my bike light for a year, it has been through hell and back with me ( think scorching hot summer and snow storms ), and surprisingly enough, it only started to fail when it was back to house duty. So following the "well it's broken, can't break it anymore" logic I decided to do my first emitter swap on it. The LED I chose was an SST20 95CRI emitter, and much to my surprise now that I measured it, it's pretty freakin great in terms of color rendering. Sadly it's now more of a "it's there if someone wants to use it" light, but it still (kinda) works.
Here are a few pictures of the body, with the dents and bruises from use
And the user inflicted scrapes when I had the remove the driver
aaaand the completely busted bezel, because on every single forum people mentioned that this lights predecessor the S2 had a press fitted bezel, so I figured this one has one too. well no, this would've been a threaded one, but yeah.. it popped out eventually ( after which I noticed the threads )
The new LED sits nicely inside, but totally not centered, the beam is absolutely messed up ( think old Maglite beam pattern )
HOWEVER the color rendering now is stunning, this is the highest I ever measured!
I mean just look at those Ra,Rf,Rg,R9 values, it's gorgeous, and with an almost perfect 0 Duv, I'm just really lost for words.
( Also this little experiment showed me that TIR optics can and will in fact mess with CRI, the same exact LED behind the FocusWorks F2 frosted TIR optics only did R9080 )
