Why should you switch from fluorescent to LED lighting?

In the last decade, LED lighting has rapidly been taking over the world of poultry lighting. Nevertheless, fluorescent lighting is still being installed in a huge number of poultry houses across the globe.

“Switching from fluorescent lighting to good LED lighting improves farm results and more.

Making the switch:

Result: improved results and a safer poultry house.
How? Let’s have a look!

   1. Higher energy efficacy

Energy efficacy

This is the amount of energy in Watt that is used to provide a specific amount of light output in lumens. Simply said: the higher the energy efficacy, the less energy is needed to realise the desired light output.

LED vs fluorescent lighting

The energy efficacy of LED lighting is way higher than that of fluorescent lighting because LED lighting produces light in a different way.

As a result, LED lighting wastes and uses far less energy (W) to produce the same amount of light (lm). When we compare our CORAX (LED) with our ED (fluorescent), we see a major difference in efficacy: 121lm/W vs 83lm/W. A difference of 46%!

Energy efficacy CORAX (LED) ED (fluorescent)
Power consumption 8.7W 36W
Light output 1050lm 3000lm
Efficacy 121lm/W 83lm/W
Efficacy difference % 46%

Benefits

Thanks to the higher energy efficacy of LED lighting, energy consumption and therefore energy costs decrease significantly. As you can see in our calculation below, switching to LED lighting can save hundreds of euros per year per house. *

Energy consumption & costs CORAX (LED) ED (fluorescent)
Wattage 8.7W 36W
Number of lamps needed 100 48
Energy consumption per year 8.7W x 100 / 1000 = 0.87 kwh x 16 x 300 = 4176 kwh 36W x 48 / 1000 = 1.728 kwh x 16 x 300 = 8294.4 kwh
Energy costs per year 4176 x €0.17 = €709.92 8294.4 x €0.17 = €1410.05
Difference 98% / €700

   2. Longer lifetime

Lifetime

This simply stands for the number of hours a lamp can be illuminated before it reaches a certain amount of light attenuation (loss of light intensity). The lifetime of a lamp is normally expressed in the expected average lifetime in hours.  

LED vs fluorescent

Again, LED lighting beats fluorescent lighting, because LED lighting produces light in a different way and because it contains no moving parts or filaments that may break or burn out.

If we look at our CORAX (LED) and ED (fluorescent) again, the difference in lifetime becomes pretty clear. Our CORAX has an expected average lifetime of 50,000 hours (+/- 6 years), whereas the ED (the lamp, not the fixture) has an expected average lifetime of 15,000 hours (+/-2 years). This means that during the lifetime of one CORAX, the lamp of the ED has to be replaced twice!

Lifetime CORAX (LED) ED tube (fluorescent)
Hours 50.000 15.000
Years 6 2
Replacements in 6 years 0 2

Benefits

Lamps that have a longer lifetime do not need to be replaced as often. Switching to LED lighting in this case benefits the farm results, since:

  • Fewer new lamps are needed for replacements over the years. This reduces purchasing costs.
  • Fewer labour hours & replacement costs are necessary to replace the lamps.
  • The downtime due to replacement is much lower, which positively influences poultry well-being and performances.

   3. Optimal light climate

Optimal light climate

Lighting has several aspects that influence poultry in their own way. Altogether, they make up the light climate and include aspects such as the light spectrum, the light colour and temperature, light flicker and so on. In an optimal light climate, the different aspects of light fulfil the needs of the poultry.

LED vs fluorescent lighting

LED lighting outperforms fluorescent lighting in all of the aspects of light, enabling it to realise a much better light climate. The main difference? In short, good LED lighting.

  • Its light spectrum simulates natural daylight better than fluorescent lighting.
  • Its light colour (temperature) can be adjusted to suit the needs of the birds in the house. This isn’t the case with fluorescent lighting.
  • Flicker-free to reduce stress. Fluorescent lighting always flickers.
  • Dims smoothly from 100-0% to simulate sunrise and sunset. This is not possible with fluorescent lighting.

Benefits

Switching from fluorescent lighting to good LED lighting improves the light climate. In this way, poultry vision, behaviour, well-being and performances are improved in multiple ways. Result: happier, healthier animals and better farm results.

   4. Higher fire safety

Fire safety

The higher the fire safety, the lower the risk of an actual fire inside a poultry house. The fire safety of the lighting installation depends on multiple factors. One of these is the voltage of the lamps and, accordingly, the cables used and the position of the accessories and the cables.

LED vs fluorescent

The risk of fire in a poultry house is lower when using 48VDC LED lighting, compared with 230VAC fluorescent lighting. Why?

  • 48VDC cables have a lower risk of starting a fire in case of e.g., a short circuit than 230VAC cables.
  • With 48VDC systems, the power supply and the driver can be placed in the service area instead of inside the house.

Benefits

As a result, with a 48VDC LED system, fewer 230VAC cables have to be used and the majority of the ones being used can be placed in the service area. This reduces the risk of fire.

Improving life through brightness

As you can see, switching from fluorescent to LED lighting can make a major difference. It improves overall farm results in multiple ways:

  • Lower energy costs
  • Lower purchasing, maintenance costs and labour costs
  • Less downtime
  • Improved poultry well-being and performances
  • Improved fire safety

BE AWARE

There are major quality differences amongst the LED lighting solutions offered. Low quality LED lighting can seriously harm both farm results and poultry well-being and performances. Don’t be “penny wise and pound foolish” when it comes to your farm equipment. Choose quality and long-term results over low purchasing costs.

*Calculation based on:

  • Type of house: broiler House
  • Measurements: 15 * 100 metres. Walls: 2.8 metres high. Ridge: at 5.2 metres height **
  • Location: the Netherlands
  • Energy price for business in the Netherlands: €0.17 excl. VAT***
  • Lamps compared: CORAX (LED) & ED (fluorescent)
  • Average time lamps are on full power: 16 hours for 300 days a year

** please note that this example is indicative. The actual figures may differ per house and per country of application.
*** energy prices in the Netherlands differ based on energy consumption. This is an indicative cost but based on actual prices.
