I understand most of you like Nichia led but the TN led 90 CRI seems not bad.
The basic data of TN led is
Size：3.45mm*3.45mm
Binned at 1050mA@85℃
Viewing Angle：120°
Max Current: 3000mA
Actually the new model IF30 flashlight uses the TN leds with 70CRI, but what I am ask for testing is the 90 high CRI version
Who is going at testing leds? Please help.
I really need professional ideas. Because I want to use this TN led but I’m afraid you would blame it.

If you can get a spectrometer result it would useful.
Only concerns from me would be the poor binning (tint lottery), tint (greenish), low R9, or tint shift (like Cree XP-G3 or XHP50.2)
Do you know if there’s a domeless version? Beam profile of dedomed 519a and XP-L HI in many Sofirn lights with LH351D is nicer and has more throw.
It took me a long time, but I finally realized I care more about tint than CRI. A green/yellow tint is worse than low CRI.
Thank you for being interested in finding better LEDs, Barry.
If you send me at least two samples I can test it, including spectral measurements, like in my previous tests.
Pls check the pm.
I’d like to see a datasheet for the C/W amlnd vF. Usually these Chinese LEDs have high thermal resistance and high vF compared to Cree and even Lumileds and Osram and aren’t too efficient.
where can you buy these ?
