Lumu Power – a Kickstarter for the ‘light meter of the future’

The new Lumu Power adds flash metering and colour temperature measurement. It plugs into an iPhone Lightning port.

Lumu Labs, the creators of the eponymous light meter that plugs into the 3.5mm jack of your iPhone have created a new Kickstarter project for their newest product, the Lumu Power. The Lumu Power is a small light meter that plugs into the Lightning port of the iPhone and is able to measure light, exposure and colour temperature.

Since the original Lumu, the new version has added the ability to measure flash and colour temperature. In the app, the colour temperature is expressed in Kelvin and Green-Magenta ratio, which both are needed for a custom white balance setting on your camera.

At the moment of writing the Lumu Power is already fully funded, but its still possible to back the Kickstarter project for $199 and get yourself a Lumu Power as well. You still have 8 days to back the project and if you do you can expect your reward to arrive at your place around June 2016.

Personally I see the addition of a flash meter and colour temperature meter as a very welcome addition to the already capable original Lumu. Normally colour temperature meters are rather expensive ($800 or much more) and I am very curious to see how well the Lumu Power will perform, in respect to accuracy and ergonomics.
