1. Product Features

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

Lighting Passport Standard: If your mobile device is iPhone 4S or later version, or Android 4.4.2 or later version, and already supports BT4.0(BLE, Bluetooth Low energy), you can choose Lighting Passport Standard version. It’s light, portable, and well worth its value.

Lighting Passport Flagship: If you are a frequent user, Lighting Passport Flagship version can provide you the best user experience with an iPod Touch inside. It also can be used separately and remotely as the Standard version.

1.2. – Can I use the Lighting Passport to measure “Lumen”?

According to the approved standard(EX: LM-79), it needs an 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 the lighting intensity.

1.3. – Is Lighting Passport accurate?

First of all, Lighting Passport is a grating-based meter with an optical resolution under 8 nm, and that is better than most portable Spectro lux meters. Second, we implemented a complete calibration system including standard spectrophotometer, standard light source and so on. In our lab we calibrate every Lighting Passport based on NIST (National Institute of Standards and Technology) criteria before shipment.

Lighting Passport also passes the notary labs tests, like the National Measurement Lab of Taiwan, China, and Switzerland so that accuracy is ensured.

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


4.2. – 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.

5. Product Use

5.1. – Is there any suggested distance between Lighting Passport and the light source?

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

5.2. – What kind of SDCM standard do you use in your APPs?

Some use the ANSI-SDCM, but we follow the IEC 60081.
