How much can you save by replacing 400W mercury vapour luminaires?
The following table shows the main energy-saving alternatives for high-bay and low-bay ‘mercury vapour’ lighting.[1]
An EcoSmart Electrician or lighting professional can tell you which of the following are the best options for your organisation.
| Alternative lighting | Estimated lifespan of new lighting | Estimated running cost reduction[2] |
| New 250W metal halide luminaire | 10,000 hours | 30–40% |
| New 200W induction lamp luminaire | 60,000 hours | 40–51% |
| New 4x54W fluorescent luminaire | 12,800 hours | 45–55% |
| New 110W LED luminaire [3] | 50,000 hours | 55–75% |
What is the difference between a lamp and a luminaire? The actual light source is called a lamp or illuminant. The light fitting with the lamp is called a luminaire.[4]
