Light the night with LEDs
Light technology has come a long way. From traditional incandescent lights came halogen, then HID, and now LED lights are taking over the spotlight. While light-emitting diode (LED) technology has been around since the 1960s, four advances are making this throwback a shining star in updated farm machinery.
1. Energy efficiency. LED lights are classified as very energy-efficient. For you, this means longer life for your machine’s batteries and alternator. It also means that you can add lights without overloading the electrical system, which is especially important with older machinery. An added perk is that no heavy pollutants are used during the manufacturing of the product, making LED lights energy-efficient and green.
Compared with other forms of lighting, LED still takes the gold for efficiency. Halogen and incandescent lights use 90% to 95% of their current draw to generate heat. LEDs, on the other hand, employ 80% of their current to generate light. High-intensity discharge (HID) lights have huge initial current draw, while LEDs have a constant current draw. Due to the lower draw, LEDs operate better at colder temperatures. LEDs turn on instantly; they don’t have the recovery period that HIDs require.
2. Color temperature. LEDs produce natural light, very similar to sunlight’s color temperature.
“Our eyes love sunlight and will not fatigue when using it, as compared with other types of lighting,” says Tyler Rouse, with John Deere. “Less operator fatigue and eyestrain means longer hours of operation and greater productivity.”
3. Longer life. LEDs have a long life with no bulbs or ballast to replace. At a life rating of up to 40,000 hours, LEDs have such a long life that they can be a lifetime light with almost no maintenance. In comparison, HID capsules last for 2,500 hours; halogen bulbs only have a rating of 500 hours.
Sealed to an ingress protection of 67 (IP67), the lights are protected from water and dust intrusion, and they can handle a power washer. Also, LEDs do not have a filament; thus, vibrations are not an issue like they were with older sealed beam lighting.
If LEDs do need to be replaced, they can simply be plugged into the same housing as the sealed beam lights.
4. Light output. For optimal viewing conditions, LEDs create little to no shadow areas around the tractor. LED has two types of directional light output: flood pattern and trapezoidal pattern. Flood pattern lights are designed for illuminating wide and short areas. They are ideal for medium-range visibility. Trapezoidal pattern lights are general-purpose work lights. These lights have a narrow pattern with long-range visibility.
Hot item in ag
Because of advances in LEDs, the lights have become a hot item in the agricultural market.
“We have seen a rapid increase in the demand by our customers for LED lighting options on older equipment,” says Rouse. “A predominant focus of that demand is usually based around our row-crop and four-wheel-drive tractors, but it’s obviously not limited to those models.”
