LED technology is the newest lighting kid on the block, and it comes with several key benefits over incandescent lights. LEDs are smaller, are much more robust, have a much longer lifetime, are much more efficient so consume much less energy, and can work at much lower voltages.  These are all features that make them ideal ingredients for compact lights for video work. They are bright, adjustable (both brightness and color), and can run for hours on battery power without producing much heat. Being small, powerful, and relatively light (pardon the pun) they are easy to attach to your laptop, desktop, tablet, or camera. Alternatively, they can be mounted on a tabletop stand that takes up little desk space.
