LED headlamp test: Not just brighter, but wider and more natural illumination
I noticed that my eyes didn’t feel as strained as they normally would during a night drive on such a dark road. This is perhaps due to the enhanced blue and white light given off by the LED lamps being a much more natural color than what’s emitted by conventional lamps, so it’s more like daytime light. Additionally, your eyes don’t have to work as hard to pick out details on the road.
As I reported these impressions to Van Riper, it turned out there is even more subtlety at work. He said Truck Lite conducted extensive research with the University of Michigan Transportation Research Institute to develop a light wavelength that’s more conducive to producing daytime levels of melatonin in the body, thereby reducing fatigue. The result, Van Riper says, is more alert drivers while on duty and less fatigued drivers at the end of a shift.
Freightliner’s move to standardize Custom LED lamps on the Cascadia is a sure indicator this technology has arrived. While Truck Lite is progressing with its product’s market penetration, Grote Industries also has been developing LED headlamp options for an equipment partner and anticipates a much broader market, says Product Manager Chris Cammack.
My impressions of the new lamps were positive: Crisp, white light that is easy on the eyes and provides longer and wider fields of view. That’s a hard combination to beat.
