For video lighting, we are always looking for the most accurate colour rendering. In fact, what we are looking for in a video light is an equivalent of sunlight or incandescent light at an output that is high enough to overpower the noise levels of the camera sensor. When plotted on a frequency chart, the light emitted by the sun or an incandescent light bulb shows as a smooth graph representing all the colours we can see. An increasing number of video lights are based on LED technology. The frequency chart of some LEDs — especially cheap ones as well as the so-called ‘white LEDs’ — shows they can’t render deep reds and blues well. This obviously reduces their usage for video production. The CRI index doesn’t help much as it’s most commonly used to help the marketing department. So, what should you be using instead? And from the three LED lights I reviewed — Akurat Lighting LL2120hc3, Akurat Lighting A1 and BALLED Pro — which are the best for video and/or photography?
