Pointing a directional light at an object isnt the same as measuring a light that has LEDs spread out. Once again you are citing bro science.
How would you know? You call hard measurements 'opinions' and vaguely cite inapplicable laws of physics.
In other words, you're ignorant and you should keep your useless opinions to yourself.
How about this? Take some relevant classes, crack some books, and actually make the effort to LEARN SOMETHING.
Of course there is the very real risk that doing so will make you embarrassed about all the stupid shit you've vomited up on these threads, I'm guessing that's the main reason you haven't.
That, and you're lazy. It's easy to sit on your ass and talk shit about everything, you've proven that we'll enough! But where's YOUR rig? Your grow? ANY new ideas at all?
What you haven't proven is that your opinions are worth the electrons it takes to push them around.
