PAR, or Photosynthetically active radiation is (very simply put) a measurement of light-radiation in a certain set spectrum.
Even simpler (but slightly inaccurately) put it's light intensity
You measure it using a Quantum-meter/PAR-meter, which is a light sensor. These are quite pricy, especially if you consider how seldom you actually "should" be using them. You can for example rent them from BRS if you want to avoid the substantial upfront cost.
Someone else will probably provide a better explanation, but I hope I've answered a few of your question marks

thank you! that helps a lot! im guessing there isn't a way to convert Kelvin to PAR then?
