Complete LED vs fluorescent lighting comparison: 5-year TCO analysis, energy savings (50-70%), lifespan (50,000h vs 8,00…
| 对比维度 | 选项A | 选项B | 优胜 |
|---|---|---|---|
| Lifespan | 50,000 hours (L70) | 8,000-15,000 hours | LED (5-6× longer) |
| Energy Efficiency | 100-180 lm/W | 60-100 lm/W | LED (50-80% more efficient) |
| 5-Year TCO (per fixture) | $80-120 | $200-350 | LED (50-65% savings) |
| CRI | 80-97 Ra | 50-85 Ra | LED (superior color) |
| Warm-up Time | Instant | 1-3 minutes | LED |
| Mercury Content | None | 3-5mg per tube | LED (eco-friendly) |
| Dimming | 0-10V / DALI / TRIAC | Limited (special ballast) | LED |
| Cold Temperature | Works at -30°C | Flickers below 10°C | LED |
LED照明在每个可测量维度均优于荧光灯:寿命长5-6倍、能效高50-80%、5年TCO低50-65%、显色更优、即开即亮、无汞、全调光。LED改造回本周期通常1-3年。
