              The ability to measure color and to instantly compute color metrics ranging from RA (CRI), R1-15, CQS and GAI, to the compliance with ANSI and IES colorimetry standards, and to the new TM-30 metrics, is in my opinion an essential part of lighting practice for everyone on the industry. I have owned a spectrometer since 2013 and cannot imagine working without one.

              Lighting Passport Essence is often the most affordable spectrometer available. If you need more color info than a simple tristimulus color meter can provide, the Lighting Passports provide it, in a compact package that won’t bulk up your gear bag.

              We purchased a Lightning Passport light meter so that we could verify the claims of grow light manufactures. The Lightning Passport gives us the tool to scientifically compare lights in a precise and constant manner thus eliminating all perceptions. As we say, the meter shows what is real.
