The Genaray LED-2100 36 LED Compact On-Camera Light will light up 25' with a 65° wide beam angle at 5600K daylight color temperature. The light will serve you best indoors and outdoors at night. (Consider adjusting surrounding light sources, your camera's white balance settings, and other associated variables to balance well with the daylight color output.) A diffuser is built in to soften the light output, so that your subjects will be lit gently and with little contrast from area to area. The light is stackable horizontally and vertically, so if you require more light, just connect additional units to the integrated shoe mounts on the top and sides, or snap them off for less light.
