Comparison of LED and fluorescent lighting. Energy consumption, lifespan, cost analysis, and which one should be preferred in which situation.

LED or Fluorescent?

The transition from traditional fluorescent lighting to LED is rapidly spreading worldwide. But is LED really more advantageous in every situation? Here is a detailed comparison.

Cost Comparison (100 Fixtures)

Fluorescent Scenario

  • Fixture + lamp: 100 x 150 TL = 15,000 TL
  • Annual energy: 100 x 36W x 10 hours x 300 days = 10,800 kWh = 37,800 TL
  • Lamp replacement in 3 years: 100 x 30 TL x 2 = 6,000 TL
  • 5-year total cost: 15,000 + 189,000 + 12,000 = 216,000 TL

LED Scenario

  • Fixture: 100 x 350 TL = 35,000 TL
  • Annual energy: 100 x 18W x 10 hours x 300 days = 5,400 kWh = 18,900 TL
  • Lamp replacement: 0 TL (5-year warranty)
  • 5-year total cost: 35,000 + 94,500 + 0 = 129,500 TL

Difference: 86,500 TL savings (in 5 years)

Advantages of LED Compared to Fluorescent

  1. 50-60% energy savings
  2. 5x longer lifespan
  3. Maintenance cost is nearly zero
  4. Instant full light (no waiting)
  5. Flicker-free (doesn’t strain the eyes)
  6. Environmentally friendly (no mercury)
  7. Dimmable (can be dimmed)

When Can Fluorescent Still Be Used?

  • Very low-budget temporary installations
  • Areas to be used for a short period
  • If the existing fluorescent system is new and working (switching to LED is recommended when it reaches end of life)
