Reasons for the switch to LED (light emitting diode) light systems are many, according to lighting experts.

 “LED light color is tuned closer to that of natural daylight, to which our eyes are best suited,” says Mike Maher of J.W. Speaker. This light produces less eyestrain, which helps to reduce fatigue, he says.

The lights use less power than halogen lights use, Maher says. A halogen light consists of a glass bulb filled with gas and a thin tungsten wire filament, which heats up when power is applied. The light is then a by-product of the heat produced in the glass capsule.

LED lights are semiconductors with solid-state electronic components that generate light when power is applied. The light source comes from an active layer of die material consisting of indium, nitrogen and gallium phosphorus that resides on a silicon carbide foundation, sometimes sliced into pieces and referred to as chips.

High-density discharge (HID) lights have a high current spike when they turn on initially, says Jacob Bolson of Hagie Manufacturing. This can cause a machine’s electrical system to malfunction. For producers using noncurrent production tractors, combines or sprayers, LED technology fills the void of limited availability of electrical power because of their low current draw, Maher says.

According to LED lighting makers, LED lights also are more reliable and have a longer life than halogen or HID lighting. Maher says that LED lights do not have a filament to wear out or break or bulbs to replace. The cost of machine operation also is lower because LED lights draw less current.

Popovic points out that an LED light provides 40,000 hrs. of light, whereas an HID light provides 2,000 hrs.

He also claims that LED lights are better for the environment. “HID has a toxic waste,” he says. “There is mercury inside HID technology, which creates pollution. LED is completely green.”
