Most warehouses currently use Metal Halides, High Pressure Sodium (orange light) or fluorescent T-Bay lighting technologies.
LEDs can save at least 64% energy consumption and cost, last longer and give off a brighter light than other lighting options.
These figures are based on changing from a 400W lamp to a 155W LED.
| LED | Metal Halide | T-Bay (HO T5) | |
|---|---|---|---|
| System Wattage | 155 | 444 | 356 |
| Load Factor (hrs p.a.) | 8,760 | 8,760 | 8,760 |
| kWh per annum | 1,358 | 3,893 | 3,115 |
| Total energy cost p.a (R1.15/kWh) | R1,561 | R4,477 | R3,582 |
| Additional energy cost p.a. | R2,916 | R2,020 | |
| Rated life to L70 | 50,000 | 10,000 | 25,000 |
| Replacement lamps required | ‐ | 5 | 2 |
