While typical lighting efficiency metrics include spill light, what truly matters is how much useful light reaches the intended area. When spill light is not properly controlled, unnecessary light intrudes into the night sky and neighboring areas. Our unique Inner Visor and reflector designs effectively prevent spill light, directing useful light directed to target areas while reducing unwanted glare. Even when compared to fixtures with higher rated efficiency on paper, Alpha Led Systems luminaires deliver superior uniformity and higher illuminance in simulations.
