Used Sony 16 watt LED Battery Powered Video Light.

• Using LED as a light source has the advantages of high intensity (600lx, 1m), extended life (10,000 hours), and low power consumption (16w).
• The HVL-LBP is designed to provide the optimum spread for wide-angle shooting with the HVR-V1U: it illuminates with uniform intensity right across the field of view. Using the attached condensing lens, you can concentrate light in the center of the picture. The attached diffuser makes it possible to soften shadows and reduce contrast.
• To power the LED light you can use the same L Series batteries (NP-F970 / 770) that are used for HVR-V1u, making this accessory as cost-effective as it is useful. It can be operated for about 3 hours with the NP-F970 battery. When the HVL-LBP is attached to the cold shoe of the camcorder it is possible to use the battery adapter to achieve a good weight balance for the camcorder.
