LED vs HPS Comparison
Efficiency, lifespan and color compared.
High-pressure sodium still lights streets and yards at a low unit price, but its 20-25 CRI makes colour work impossible and its 15,000-24,000 hour lamp life means regular relamping. LED closes the gap on first cost and wins on running cost.
| Comparison | Option A | Option B | Winner |
|---|---|---|---|
| Efficacy | 100-180 lm/W | 80-140 lm/W | LED |
| Lifespan | 50,000-100,000h | 15,000-24,000h | LED |
| CRI | 70-95 | 20-25 | LED |
| Warm-up | Instant | 5-10 minutes | LED |
Conclusion
Replace HPS with LED where colour rendering, instant restrike or maintenance cost matter — car parks, logistics yards and streets with CCTV. Keep HPS only where a legacy photocell and ballast system must stay untouched.
