Here you will see what the Lume Cubes do to bring your night time videos and photographs to life. I have them setup on the GoPro mount and run through the various brightness levels. These lights are bluetooth driven and give your smartphone the ability to shoot great video and photos in the darkest areas. They are the first off-device strobe for any smartphone and has an app that makes their uses unlimited. Whether you need these as a flash for your iPhone or Android device, or to enhance your dslr photography by using them as a slave flash, they will do the work.
