What’s the difference between Lighting Passport Standard version and Flagship version?

If your mobile device already supports BLE(Bluetooth Low energy), like iPhone 4S and iPhone 5, you can choose Lighting Passport Standard version. It’s light, portable, and well worth its value.If you are a frequent user, Lighting Passport Flagship version can provide you best user experience with an iPod touch inside. It also can be used separately and remotely as Standard version.

What’s the communicating protocol between Lighting Passport and mobile device?

We adopt BLE(Bluetooth Low Energy,BT4.0).It can provide considerably reduced power consumption and make devices stable and durable.

Does Lighting Passport support my mobile device?

Lighting Passports can be used with iOS devices now, including iPhone4S ,iPhone5 ,iPod touch 5,iPad mini ,the New iPad(iPad 3) and above version. Because iPod touch 5 16G isn’t with back camera.

What is the longest distance for remote measurement of Lighting Passport?

Depends on the amount of interference. We suggest that the distance between the mobile device and Lighting Passport have to be less than 7 meter.

Does any Suggested distance between Lighting Passport and the light source?

The distance is related to light intensity and light pattern.
For illuminance, Lighting Passport can accurately measure light source from 100 to 50,000 lux, and you can adjust distance based on this.Some companies provide the illuminance (lux) of 1 meter, 2 meter and 3 meter. For outdoor lighting, often measure the light source at the similar height of human body. For indoor lighting, often measure the light source at 80~100 cm.We also suggest you to use auto integration mode to save the time for distance adjustment.

Could I use the Lighting Passport to measure “Lumen"?

According to the approved standard(EX: LM-79), it needs integral sphere to measure “Lumen".There is no portable meter that can really measure “lumen"(total flux) of the luminaire. Lighting Passport can measure illuminance which is a good reference of lighting intensity.

Is Lighting Passport accurate?

First of all, Lighting Passport is a grating based meter of which optical resolution is under 8 nm, and that is better than most portable spectrolux meter.Second, there is complete calibration system including standard spectrophotometer, standard light source and so on. In our lab, we traced NIST(National Institute of Standards and Technology) criterion to calibrate every Lighting Passport before shipment.
Lighting Passport also pass the test by notary labs like National Measurement Lab of Taiwan, China, and Switzerland, the accuracy can be ensured.

Have any Safety assurance?

Spectrum Genius Mobile

“Spectrum Genius Mobile" is an APP used in conjunction with the “Lighting Passport", it provides users comprehensive lighting measurement functions. In Single Mode, users can get one-time measurement report of the observed object(s); Multiple Mode allows users to test and compare various light sources easily and efficiently; Continuous Mode supplies users to continuously measure a light source for an extended period of time to check for its quality and consistency; Comparison Mode can make two “single measurement" reports to compare the spectrum and every parameter.


Spectrum Genius Essence

The APP “SGE" for “Lighting Passport Essence" there are two main measurement features, “Single" and “Multiple" measurements. “Single Measurement" allows users to quickly obtain data (CCT, CRI, CQS, illuminous, foot candle, CIE1931, CIE1976, spectrum, C78.377, IEC-SDCM, λp) on the fly. “Multiple Measurement" allows users to measure multiple light sources and create a data chart for quick references and comparison.


Spectrum Genius Transmittance

“Spectrum Genius Transmittance" is an APP for measuring the transmittance of the observed object. With the convenient measuring, users can get the transmittance report of each wavelength, and users can also compare the transmittance of different objects. This App can be extensively used in Lens, Filter and Screen Protector Membran.
