The Lumu Power iOS light meter is so accurate it is will successfully replace your Sekonic or Gossen. Lumu Power is the light, exposure, flash and color temperature meter for the iPhone. One device with power of many. The Lumu Power light meter is a hardware sensor combined with an iOS app. It has both a fast-response silicon photo diode and true colour sensor in a package the size of a big marble. The Lumu Power light meter sensor is half a sphere with a stainless steel housing and polycarbonate Lexan diffusers.

The sensor behind the dome is a fast-response Silicon photo diode. It responds to light even in near-darkness and accurately measures exposure for the Photo ambient and Cine/video functionalities. Capture flash for those frozen-moment images even at 1/40,000s.

​Photo Ambient Exposure / Flash / Cine-Video

  • Measuring range: -4 to 20EV at ISO 100
  • Accuracy: +/- 0.1 EV
  • Light receptor: fast-response Silicon photo diode, CIE spectral luminous efficiency
  • Hemispherical Diffuser, Cardioid-type responses
  • Flash duration measurement: 1/40,000 - 1/250 s

The sensor on the flat side is a True Color Sensor with CIE 1931 Color standard Human eye perception, one of the most accurate sensors on the market. Along with Color Temperature and Chromaticity, Illuminance is also measured with this sensor because of the cosine type response.

 

Color Temperature

  • Sensitivity: Visible light
  • Dynamic range: 1:1,000,000
  • Measuring range: 1500K - 20,000K
  • Accuracy: < 0.6 deltaE
  • Repeatability: < 0.2 deltaE
  • Flat Diffuser, Cosine-type response

Illuminance

  • Measuring range: 0.15 - 250,000 lux
  • Accuracy: +/- 3%
  • Flat Diffuser, Cosine-type response

Other
