Extra light makes a big difference in video productions. And that's exactly what Sirui's E30B has to offer you. Actually, much more than that. Because the built-in soft filter provides over 700 LUX at 1 meter. Soft light, of high quality. And that's really special from such a compact, flat lamp. The secret is the 6-layer internal filter. This ensures that soft light is spread evenly over the surface of the lamp. Many lighting effects and CCT control make the video panel widely usable.
