I know, I dont particularly understand that. If you have 1 100watt bulb and you have 10 there are the same amount of lumens? This cant be true, please someone explain this. lumens measure the brightness of a light to the human eye, PAR Watts are the total watts of Photosynthetically Active Radiation i.e. PAR. this is basically how much light is used for photosynthesis
