Obtain scientifically accurate PAR light readings under any light source, including LED

You don't have to break the bank to acquire a quality photosynthetic active radiation (PAR) meter ... affordable models can be just as effective. In side-by-side reading comparisons, the SpotOn Quantum PAR meter was just as accurate as a more expensive, laboratory-grade unit.
