Sodium lighting could save the pennies!

Farmers can reduce the cost of lighting farmyards and farm buildings by as much as 50pc, according to the IFA's 'Smart Farming' guide.

Lighting is one of the easiest areas of the farm to save money by providing the right amount of light, in the right place and at the right time with effective lighting equipment.

Light efficiency is measured in lumens per watt and the higher the lumens per watt, the greater the lighting efficiency.

Replacing a 500-watt halogen flood light with an equivalent light output 150-watt high pressure sodium lamp will save €128/year and last 10 times longer than the halogen light.

For yard lighting, high pressure sodium lights are best because they offer a balance between colour rendering and high efficiency.

For the most efficient use, they should be controlled with a dawn to dusk sensor and time switch.

Inside farm buildings, the IFA guide advises farmers to think about safety and pay attention to the suitability of light fittings for the humid, dusty and warm environments often found in cattle, pig and poultry sheds.

The new energy efficient standard is the T5 fluorescent tube with dimmable electronic ballast, mounted in a weather-proof plastic housing.
