Benefits for teachers (reduced fatigue, fewer headaches) and students (improved focus, reduced off-task behavior). Fluorescent and LED options. Common fixture: 2×4 troffers. Bulk purchasing common via quote form. ### [Office Lighting](https://www.makegreatlight.com/solutions/office-lighting/) How NaturaLux™ reduces headaches, eye strain, and fatigue in open-plan offices and cubicle environments. HR and facility manager use case. Common trigger: fluorescent troffer flicker + UV + harsh spectrum. ROI framing: fewer sick days, accommodation compliance. ### [Healthcare Lighting](https://www.makegreatlight.com/solutions/healthcare-lighting/) UV blocking for laboratory environments (UV degrades specimens). Glare reduction for clinical staff comfort during long shifts. Not a patient-comfort product — buyer is typically clinical director or facilities team. Labs need UV protection; clinical areas need glare reduction. --- ## Health Conditions ### [All Conditions](https://www.makegreatlight.com/conditions/) Overview hub for light-related health conditions that NaturaLux™ addresses. ### [Fluorescent Light Headaches](https://www.makegreatlight.com/conditions/fluorescent-light-headaches/) Explains the three mechanisms: UV radiation, flicker effect (undetectable to the eye but processed by the brain), and harsh blue-spectrum light. NaturaLux™ addresses all three. ### [LED Light Headaches](https://www.makegreatlight.com/conditions/led-light-headaches/) LED-specific triggers: blue light spike, flicker (PWM dimming), high-frequency pulse. Growing issue as offices replace fluorescent with LED. NaturaLux™ LED covers correct spectrum and reduce perceived flicker effects. ### [Light Sensitivity](https://www.makegreatlight.com/conditions/light-sensitivity/) Photophobia and photosensitivity from various causes. Overhead lighting is often the primary environmental aggravator. NaturaLux™ as an accommodation strategy without requiring personal eyewear. ### [Lupus](https://www.makegreatlight.com/conditions/lupus/) Lupus photosensitivity (UV sensitivity as a lupus symptom). Fluorescent and LED lighting emits UV that can trigger flares. NaturaLux™ blocks 100% UVB and up to 98% UVA — relevant as an ADA accommodation for lupus in the workplace. ### [Irlen Syndrome](https://www.makegreatlight.com/conditions/irlen-syndrome/) Scotopic sensitivity — visual processing disorder where lighting (especially fluorescent) distorts reading and causes fatigue. NaturaLux™ reduces the full-spectrum distortions that aggravate scotopic sensitivity. ### [Autism & Sensory Processing](https://www.makegreatlight.com/conditions/autism-sensory/) Sensory sensitivity to fluorescent flicker, UV, and harsh spectrum. Common accommodation request in schools and supported employment settings. NaturaLux™ reduces the sensory load of overhead lighting without altering the fixture. ### [Seasonal Affective Disorder](https://www.makegreatlight.com/conditions/seasonal-affective-disorder/) SAD and the relationship between light spectrum and mood regulation. Full-spectrum light (including NaturaLux™ corrected output) better supports circadian rhythm than standard fluorescent. --- ## Resources & Research ### [All Resources](https://www.makegreatlight.com/resources/) Hub linking to research, whitepaper, and video content. ### [Full Spectrum Light](https://www.makegreatlight.com/resources/full-spectrum-light/) Explains what full-spectrum light is, how it differs from standard fluorescent and LED, and why the spectrum matters for human health. ### [Lighting Health Research](https://www.makegreatlight.com/resources/lighting-health-research/) Curated peer-reviewed studies on the health effects of workplace lighting. Covers circadian rhythm, UV exposure, flicker, and productivity. ### [Lighting Health Videos](https://www.makegreatlight.com/resources/lighting-health-videos/) Video resources on lighting health topics — Vimeo-hosted content. ### [Natural Light Classroom Research](https://www.makegreatlight.com/resources/natural-light-classroom-research/) Research specifically on natural/full-spectrum lighting in classroom settings and academic performance outcomes. --- ## Blog (59 articles) [Blog index](https://www.makegreatlight.com/blog/).
