Use LED Lighting for a Video


LED lights, light emitting diodes, work by converting electricity into light. LED lights are more durable than traditional fluorescent or incandescent lighting, and when turned on LED light panels provide a steady stream of non-flickering light, according to NAHB Research Center. China LED lighting for video lighting can be an ideal way to illuminate a scene as these lights do not run hot and they provide an even glow, which is ideal for illuminating a subject.
Instructions
1 Purchase the appropriate lighting panel for your use. The size of an LED light panel depends on how much of the subject you will need to light. A standard video light setup should have a medium-sized light panel with a smaller mini panel to counterbalance shadows. If you will be interviewing a person on video, a ring-shaped LED panel will cast an attractive glow on the subject without causing a white-out on the subject's skin.
2 Set up the lights. Use the larger LED panel light manufacturer as your key light, which is the brightest light within the setup. Position the light as you would with a standard incandescent light, usually at about a 45-degree angle diagonally in front of the subject. Balance the light given by the key light by setting up a fill light. This light should be smaller than the key light and around 50 to 75 percent dimmer. Most LED light panels have a built-in dimmer, which does not alter the color of the light but simply changes its brightness. Position the fill light on the opposite side of the subject to remove shadows created by the key light.
3 Adjust the brightness levels of the LED light panels. Because LED light panels do not get hot, you can place the lights as close as needed to the subject without the fear of burning or whiting out the subject. Once you have positioned the lights and adjusted their brightness, call "Action" and let the magic of filmmaking begin.
Tips & Warnings
Purchase at least three different professional LED street lighting. Depending on the shot you wish to create, you may need to place more than two lights on the subject.
Set light angles and levels by referencing your video camera monitor to get a sense of how the subject looks on film. Do not simply set up the lights and begin filming. Take time to establish the light locations and play with the brightness levels of the panels until you have the ideal lighting situation.
