Lightpanels Micro LED Toplight

You can use this as a camera top-light. It’s powered by AA batteries and is dimmable. Although it’s not bicolour it comes with CTO correction and diffusion filters so you can use it in a tungsten environment. These are small enough to be used in a vehicle or in confined situations but big enough to produce a useful amount of light. They are almost twice as powerful as most small LED camera top-lights.
