LED vs Metal Halide Comparison
Retrofit economics for industrial lighting.
Metal halide delivers good colour but pays for it: 60-110 lm/W, a 5-15 minute restrike after a power dip and 10,000-20,000 hour lamp life. LED retrofits remove the restrike problem and cut maintenance visits.
| Comparison | Option A | Option B | Winner |
|---|---|---|---|
| Efficacy | 100-180 lm/W | 60-110 lm/W | LED |
| Lifespan | 50,000h+ | 10,000-20,000h | LED |
| Restrike | Instant | 5-15 minutes | LED |
| Maintenance | Low | High | LED |
Conclusion
For high-bay factories and sports halls running long hours, LED retrofit pays back inside two to three years once maintenance labour is counted. Keep metal halide only where the installation is decommissioned soon.
