How Should Office Lighting Be? LED Panel Selection, Lux Calculation, and Efficiency Guide 2026

Why is Office Lighting Important?

Proper office lighting can increase employee productivity by 10-20% and prevents eye strain and headaches. Incorrect lighting, on the other hand, leads to employee dissatisfaction and loss of productivity.

Office Lighting Standards (EN 12464-1)

Area Lux UGR Color Temperature CRI
General office 500 lux <19 4000K 80+
Computer work 500 lux <19 4000K 80+
Meeting room 500 lux <19 4000K 80+
Reception / lobby 300 lux <22 3000-4000K 80+
Corridor 100 lux <25 4000K 80+

What is UGR? Why is it Important?

UGR (Unified Glare Rating) = glare discomfort index. Low UGR = less glare = less eye strain.

  • UGR <19: Standard for office and computer work
  • UGR <16: For sensitive visual tasks

Office LED Luminaire Selection

1. LED Panel (Most Common)

  • 60x60cm or 30x120cm sizes
  • UGR <19, 4000K, flicker-free
  • Homogeneous light distribution — no shadows

2. Linear LED Luminaire

  • Ideal for open-plan offices and co-working spaces

3. Recessed Spotlight

  • Meeting room, reception, executive office
  • Dimmable — for presentation and meeting modes

Fluorescent vs. LED Panel: Real Cost Calculation

Fluorescent T8 LED Panel Savings
Power (60x60) 2x36W = 72W 40W 44%
100 luminaires/year (2,500 hours) 18,000 kWh 10,000 kWh 8,000 kWh
Annual cost (5 TL/kWh) 90,000 TL 50,000 TL 40,000 TL/year

Common Mistakes

  • ❌ Not paying attention to UGR value — glaring luminaires harm employee health
  • ❌ Choosing flickering products — headaches and eye strain
  • ❌ Not installing sensors and dimmers — lights left on waste thousands of TL annually

FAQs

Which LED panel should be chosen for the office?
A 60x60cm LED panel with 500 lux, 4000K, UGR <19, and flicker-free features is the standard choice.

How long does it take for office lighting to pay for itself?
Typically 2-3 years. With smart sensor and dimmer systems, this period can be reduced to 1.5 years.

Is there a discount for bulk orders?
Yes! For orders of 50 units or more, we offer corporate pricing and priority delivery.
