If you’re lighting a factory, warehouse, stadium, or street, you’ve likely
faced the choice: stick with traditional metal halide, or switch to LED? It’s a
common question — and an important one, because the right choice affects your
electricity bill, maintenance effort, and light quality for years. Here’s a clear,
side-by-side comparison to help you decide.
Energy Efficiency
This is where LED wins decisively. Metal halide lamps waste much of their energy
as heat and scatter light in all directions. LEDs convert far more power into
usable, directed light — using 50–70% less electricity for the same brightness.
For high-usage industrial and outdoor lighting, this is the biggest difference.
Lifespan & Maintenance
Metal halide lamps last roughly 6,000–15,000 hours and lose brightness quickly
as they age. LEDs last 50,000+ hours and hold their output far longer. Metal halide
also needs ballast replacements and frequent re-lamping — costly when fixtures are
mounted on tall poles or high ceilings. LEDs dramatically reduce this burden.
Light Quality
Metal halide colour shifts and fades over time, and lamps take several minutes
to warm up to full brightness. LEDs give instant, consistent, high-quality light
with better colour rendering (CRI) — crucial for safety, productivity, and
broadcast-quality sports lighting. LEDs also restart instantly after a power cut;
metal halide needs a cooldown before restriking.
Upfront Cost vs Total Cost
Metal halide fixtures are cheaper to buy upfront — this is their only real
advantage. But once you factor in energy, lamp replacements, and maintenance,
LED’s total cost of ownership is far lower. Most industrial LED upgrades pay back
within 1.5–3 years, then keep saving for the rest of their long life.
Side-by-Side Summary
| Factor | Metal Halide | LED |
|---|---|---|
| Energy use | High | 50–70% lower |
| Lifespan | 6,000–15,000 hrs | 50,000+ hrs |
| Warm-up time | Several minutes | Instant |
| Light quality | Fades over time | Consistent, high CRI |
| Maintenance | Frequent | Minimal |
| Upfront cost | Lower | Higher |
| Total cost of ownership | Higher | Lower |
Conclusion
For almost every industrial and outdoor application — factories, warehouses,
streets, stadiums, floodlighting — LED is the clear winner on energy, lifespan,
light quality, and total cost. Metal halide’s only edge is a lower purchase price,
which is quickly erased by running costs. If you’re planning an upgrade, Reway’s
BIS-certified LED range
covers every industrial and outdoor need.
