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.
Make those large LED Video Light Panels more portable by running them off of batteries. Here's a random little video showing you how to power up those CN-600 / CN-900 LED Video Lights using the 14V Sony BP-U30/U60 batteries. It's not the cheapest solution, but compared to other batteries available, it's not too shabby.
This was the same battery adapter that I showed earlier which acts to power up your BlackMagic Cinema Camera. You can find the products below.
