The S30 LED Focusing LED Light from Godox is a lightweight, versatile source with light intensity, beam spread, and power options. The S30 has an adjustable beam angle of 6 to 55 degrees for long throw work or to flood out a silk. The output can be further controlled by swinging one or more leaves of the 8-way barndoors into the beam path to facilitate selective lighting. The S30 is also dimmable from 10 to 100% to save you the trouble of jockeying it back and forth for the desired light intensity. Ideal for shooting outdoors or seamlessly integrating with daylight-balanced fixtures, the S30 has a solid 5600K color temperature with a high CRI/TLCI rating of 96 that indicates impressive accuracy in the rendering of color. The S30 is ready for worldwide use using the included AC adapter, but it will also run on a separately purchased NP-F battery when mains power is unavailable, or an optional power bank using a USB cable.
