Best in Class Light Meter

The Asensetek Lighting Passport is the world’s first Smart Spectrometer. It enables lighting professionals to quickly and easily take accurate measurements of any light source, including CCT, CRI, TLCI, Flicker and much more. The Essence Pro version is the scaled-down (but still incredibly useful!) version of the Lighting Passport Standard Pro. It communicates to your smartphone via Bluetooth wireless, so it does not need to be physically attached to the phone when taking readings.

Great for lighting audits, colour matching to existing installation, quality control and more.

Its revolutionary design uses the computing power of your smartphone with powerful apps, instead of old-fashioned, quickly outdated dedicated hardware of comparable devices on the market.
