RCtestflight on YouTube was dissastisfied with only being able to light up entire mountainsides from four kilometers away, so replaced the enormous array of LED lamps atop his truck with ones including parabolic reflectors.
I initially built a 4kW LED array using 40 100W emitters with 60 degree glass lenses, but the beam was a bit to wide to be practical for use on a vehicle. After that I built a 1.8kW array using 18 100W emitters with parabolic reflectors. It had much better long distance throw and was way more practical.
It requires more than 5kw of power to operate.
