Summary: The Canon VL-10Li II On Camcorder Battery Video Light is a must-have for illuminating your subject with the Canon XH-A1 camcorder. The 10 watt light works as advertised with the only drawback being it requires a separate Canon battery in order to use it. It fits smartly onto the camcorder and throws enough light to illuminate subjects 10 or 15 feet distant. The price of the VL-10i is a plus. Recommended.
