Lumu Power Light & Color Meter for Photo and Video
Key Features
  • Exposure, Illuminance & Color Metering
  • Supports Ambient and Flash Lighting
  • Powered by Your iOS Device
  • Measuring Range of -4 to 20 EV
Take your photos and videos to the next level with the Lumu Power Light & Color Meter. This device attaches to iOS devices running iOS 8.0 and up through the Lightning port. It has two sides: the dome side measures ambient and flash exposure up to 750,000 times per second with a range of -4 to 20 EV, and the flat side measures illuminance, color temperature, and chromaticity using a True Color sensor based on the CIE 1931/DIN 5033 color standard. Illuminance can be measured in a range of 0.15-250,000 lux and color temperature from 1500-20,000K. The Chromaticity Mode displays coordinates in the CIE 1931 color space.

It uses a free iOS app to display color and light information on your screen so you can adjust your shots accordingly. The Lumu Power needs no batteries; it runs off your iOS device's power. It's made of stainless steel and Lexan polycarbonate for durability.

Can the flat side be used for exposure readings ...

Can the flat side be used for exposure readings as well as luminance? This would be useful for using the Duplex method.
Asked by: Arne
No, the flat side is for color readings only.

question

How accurate is the colour temperature reading on this?I used to use Sekonic meter earlier but it's no longer available. other options are too expensive. plz advise.Thanks in advance.
Asked by: Yogesh
Thinking about purchasing one and I will test it against my Minolta Color Meter. But DO NOT hold the Lumu like in the picture that Jasper posted in the reviews. Of course it's going to give an inaccurate and warmer reading if you're hand is right next to the sphere. The sphere should be at the top when taking reading and be unobstructed. Duh!

question

Can it measure the CRI of a light?
Asked by: ALLEN D.
I don't think so. It measures R, G &amp; B levels specifically, not a continuous spectrum. So it will give you Color Temperature &amp; Green Shift; Chromaticity (x, y, Duv, CCT, and Lux); Illuminance in Lux; Cine/Video, Photo Flash (overall light measurement with % contributed by flash); and regular incident light exposure readings.

question

Can it measure the color temperature of a flash. For example if I add a gel and want to take a reading to match ambient light? I assume not but checking.
Asked by: Paul
Yes. It can. But use a cover (Black paper OK)to around the flash light first then check it. It should be get a true color temperture.
