Three LEDs fan out and very bright. This allows one light to illuminate multiple steps when the light is wall mounted to the side of the steps. They light up the steps nicely. Also, the small light is very unobtrusive, so it's barely noticeable unless the LEDs are on. Each device draws about 35mA, so I powered four of them with a small 12V DC wall transformer. Power left over from a long-gone electronic device (but I kept the power supply). Strangely the light pack says 9-12 VDC (in English) but 9-16 VDC in the Spanish and French versions of the specs.
