Cutting the cost of halogen floodlights
Halogen lighting for outside use can be very cheap to buy, but it uses a lot of energy and might only last for up to 2,000 hours.
The following table shows the main energy-saving alternatives when it comes to replacing an outside 500W halogen floodlight.[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 150W metal halide floodlight | 10,000 hours | 66% |
| New 110W LED floodlight. [3] | 50,000 hours | 85% |
Easy Carwash, NT
Easy Carwash in Alice Springs replaced 25 metal halide floodlights (250W) with 150W induction lamps. The instant ‘strike and re-strike’ nature of induction lighting also enabled them to install motion sensors, which generated further savings. The capital cost was $12,265 and the payback is $4,127 a year. Given the long life of induction lighting, the eventual savings will add up to many thousands of dollars.
If they had installed LED floodlights, the savings could have been even bigger still.[4]
