Measuring 18.5 x 15 x 3.4", the 1200SA Daylight LED Panel from Nanlite is a budget-friendly light source with color temperature of 5600K for easy integration with other daylight fixtures or for shooting outdoors. The light's high CRI/TLCI rating of 95/93 is an indicator of accuracy in color rendering. Light intensity is variable too, from 0 to 100%. The 1200SA's output can be contoured and controlled by the included 4-way barndoors; simply swing one or more of the leaves into the beam to light areas of the subject that you want to and keep light from areas that you don't want illuminated. Power is handled by the included AC power supply, but the light can also run on optional V-Mount batteries when mains power is unavailable.
