Does twice the lights = twice the par?

I know that a 200watt light produces more lumens than 2 x 100watt lights. So you would think it works the same with PAR. Right?

Short answer: Not necessarily, but there should be some correlation between wattage and PAR output.

"PAR means Photosynthetically Active Radiation and that defines the main portion of light used by plants (350-750nm)*
PAR watts is the mesuare of the actual amount of specific photons a plant needs to grow,
*There is no certain of the exact  PAR zone, most scientists make their calculations based on 350 to 750 nanometers."


Each bulb have diferent PAR rating and it depends also on your bulb Kelvin temp.

So, i think twice the lights = twice the par is false, unless the bulbs are the same.
