Have you ever wondered, "What is CRI?" What about TLCI?? In todays video, we dive deep into the world of lighting metrics using the remarkable Sekonic C-800 spectrometer.
Get ready to uncover how a spectrometer works, the CRI definition, along with insights into spectrum distribution, TLCI and more. We've provided practical examples to simplify each metric for you. By the end of this video you'll feel confident making informed decisions when selecting lighting fixtures for your projects.
Explore how the C800 spectrometer functions and understand why it's revolutionizing the way cinematographers and gaffers evaluate lighting. Plus, gain exclusive access to real-world comparisons between various light sources, from tungsten to LED to sodium vapor street lamps.
Part one of this series focuses on spectrum distribution, CRI, and TLCI, with part two covering TM-30, SSI, and more! So don't miss out!
A huge shoutout to Sekonic and Kayell for providing us with the C-800 and enabling this educational series.
Let's illuminate the world of lighting metrics together!

NOTE:
- I made a mistake in the video and incorrectly labelled TLMF. It stands for "Television Luminaire Matching Factor", not "Television Lighting Matching Factor" as stated in the video.
- I also wanted to note that the CRI scores are calculated using R1-R8 only and do not factor in R9-15 in the Ra value.
- You may notice some slight variations between the live recordings and the measurements from the screen capture images, which were collected separately at a later time. These minor variations are normal and within an acceptable margin.
