Why do some lights FEEL AMAZING?

Ever wonder why some rooms just feel better than others? Why certain lights make you tired, give you headaches, or make everyone look slightly dead? Turns out there's a whole hidden world of light quality that most people never think about. In this video, we dive deep into what actually makes a light “good,” further than warm/cold and bright/dim. We'll talk about spectrums, why your body might be getting blasted with blue light even when a bulb looks warm, why that CRI number on the box is lying to you (kind of), and how flickering lights might be messing with your nervous system without you even noticing. By the end, you'll know exactly what to look for when buying lights, how to read the specs that matter, and how to set up your home lighting to work with your biology. Fair warning: you might end up wanting to build your own lights like I did. 😅 - Why light quality matters for sleep, mood, and feeling alive - The spectrum of light and why LEDs have that sneaky blue spike - CRI explained (and why 80 isn't actually "good") - R9: the number you should actually care about - TM-30: the better measurement standard nobody uses - Flickering and PWM dimming - Practical tips for daytime vs nighttime lighting - Home automation with adaptive lighting Resources: - LC Focus LED chips (AliExpress): https://s.click.aliexpress.com/e/_c4aCkj8X - Light bulb database: https://optimizeyourbiology.com/light-bulb-database - Adaptive Lighting for Home Assistant: https://adaptive-lighting.nijho.lt/ If you end up down the rabbit hole of building your own lights, let me know in the comments — I'm working on that project myself and will be sharing the journey here. 00:00 - Introduction 01:14 - Understanding Light Quality 02:32 - Light Color Information is Wrong 04:25 - Why Light Quality Matters 09:35 - What Makes Good Light Quality? 17:00 - How Can You Know? 25:47 - Your Home Lighting System
