Light & Power For Your GoPro — Film for 24 hours of the day with a GoPro. It’s possible now with this GoPro add-on, called the All Night unit from Brunton. It connects to a GoPro and offers two things: A battery pack that powers the camera up to five times longer than the internal battery alone; and an integrated light.
At 400 lumens, the LED light puts out a solid beam for shooting in low-light or even in the dead of night when it’s pitch black but you still need to film. ($149; July 2015)
