It runs entirely on solar energy that's stored in rechargeable batteries for use at night, when the light is activated by motion. The light provides generous illumination up to 3000 Lumens, excellent for deterring threats or illuminating a driveway or patio.

The power P in watts (W) is equal to the 0. 09290304 times the illuminance Ev in lux (lx) times the surface area A in square feet (ft 2), divided by the luminous efficacy η in lumens per watt (lm/W): P(W) = 0. 09290304 × Ev (lx) × A(ft 2) / η(lm/W).
