What is the real CRI of WaveFrom’s CENTRIC DAYLIGHT™ Full Spectrum bulb?
According to the Product Specifications: CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb – Waveform Lighting it has a:
CRI (Ra) = 95+
CRI R9 = 80+
However, according to this Google Sheet: BLF - Ultimate LED Bulbs - CRI Qfactor - Google Sheets it has a:
CRI Ra = 98
CRI R9 = 95
There seems to be a vast discrepancy between the CRI R9 reported by WaveForm Lighting and the test performed by Maukka.
Which one is to be relied on?
I did come across a report by WaveForm Lighting: https://www.waveformlighting.com/photometrics/TR_4005.40.pdf that seems to mimic Maukka’s test results but it seems odd that the website itself reports a much lower CRI R9.
If anyone has guidance on this issue I would appreciate it.
