Here's a new update regarding Kamerar's Brightcast Flexible Water Resistant LED Panel. The first version was only available for V-Mount batteries, possibly something not many people had or was willing to purchase. The new model is now available to support Sony's U-Mount battery. The U-Mount battery might be best known for use with the popular Sony EX1 camera, but is also used on today's Sony FS5 and FS7 cameras - so many of you may already have these. These batteries are available in different capacities (smaller to larger) such as the BP-U30, BP-U60, and BP-U90 sizes and offer 14.4V output which allows the Brightcast LED to operate at it's max brightness.
