I use these LED panels to illuminate landscapes when photographing the Milky Way at night. You need surprisingly little light to balance the foreground and sky. Even with full blackout and a red filter, there is still too much light. I actually opened one up and cut through the PCB foil with a razor knife so only 1/4 of the LEDs would light up. I used to cover part of the lantern with duct tape, but now I don't have to do that anymore. I also bought some lightweight mini tripods and some cheap flashlight stands since you want to get the flashlight off the ground. https://www.amazon.com/gp/product/B013E0FIPY/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 I've seen people holding this light for light painting and it's great for that. Use a red filter for more natural light. I adjust the light and take a test photo. I adjust the light as needed to get the right level of light and soft shadows. I now have 100% reproducible lighting for multiple exposures.
