# WorldProductivityDay

Behind every comfortable and productive workspace, there's one often-overlooked factor: lighting. Lighting is not just about brightness; it has a direct impact on visual comfort, mental focus, and overall work performance.

Here are 4 lighting elements proven to influence human productivity:

1. 💡 Light Intensity

Lighting that is too dim causes eye fatigue, drowsiness, and reduced motivation. On the other hand, lighting that is too bright can strain the eyes.

📌 Tip: Use lighting with appropriate brightness for workspaces — typically around 300–500 lux for office environments.

2. 🎨 CRI (Color Rendering Index)

CRI measures how accurately a light source reveals the true colors of objects. Low CRI makes colors appear dull and hard to distinguish — critical in design, printing, or visual industries.

📌 Tip: Choose lights with CRI >80 for more natural and accurate color rendering.

3. 🙈 Glare (Silau)

Glare is the uncomfortable brightness caused by poorly diffused light, often from direct sources. It disrupts comfort, focus, and can even trigger headaches.

📌 Tip: Use diffused lighting or anti-glare fixtures, and avoid placing light directly above desks or screens.

4. 🌡️Light Color (CCT – Correlated Color Temperature)

The color of light affects work psychology.

• Warm white (<3500K): Relaxing atmosphere.
• Neutral white (4000–5000K): Ideal for focus.
• Cahaya putih dingin (>5000K) bisa terlalu ‘dingin’ dan melelahkan jika terlalu lama digunakan.

📌 Solusi: Gunakan warna netral untuk ruang kerja agar seimbang antara kenyamanan dan semangat.

✨ Conclusion

Proper lighting can boost:

✅ Focus and concentration

✅ Mood and work energy

✅ Visual accuracy

✅ Long-term eye health

On this World Productivity Day, let’s encourage workplaces to take lighting design seriously.

Because good lighting = productive teams.
