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.
Technical Comparison Table
| Feature | Fluorescent (T8) | LED Tube (T8) | LED Panel |
|---|---|---|---|
| Power | 36W | 18W | 40W |
| Luminous Efficacy | 80 lm/W | 140 lm/W | 120 lm/W |
| Lifespan | 10,000 hours | 50,000 hours | 50,000 hours |
| CRI | 65-80 | 80-95 | 80-95 |
| Start-up Time | 2-5 seconds | Instant | Instant |
| Flicker | Yes | No | No |
| Mercury | Yes (harmful) | No | No |
| Dimming | Limited | Full | Full |
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
- 50-60% energy savings
- 5x longer lifespan
- Maintenance cost is nearly zero
- Instant full light (no waiting)
- Flicker-free (doesn’t strain the eyes)
- Environmentally friendly (no mercury)
- 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)
