Yep... marketing is one heck of a drug... I still remember being a new grower walking into the grow shop with a huge sign over my head saying "gullible" and walking out with hundreds of dollars of bottled nutrients and extra supplies I didn't need.. LOL. I'm so glad I found the forums and could nerd out on the plentyful information here. Saved me a lot of money after learning the ins and outs of growing. oh the memories..You are absolutely 110% correct and fully explained all the variables.
Now imagine a stoner who knows nothing about lights, electricity, chip BIN, or drivers. They need help picking a light for there first 2x2 grow tent. They stand in the light isle overwhelmed. The salesman gave that explanation. There blood shot eyes would glaze over half way through. Still nodding there head in agreement, they would respond " So,,, yea,,,like,,I was thinking, the green box one with 5000 on it? because like, the green plant." Head in hand you would mutter the 1000 series is what you need. For some people series is a
Crazy how psychology and marketing go hand and hand with buyer choice... I recall the one time they took a payless shoe store and "converted" it to a high end brand shoe store by upping the pricing and changing the logos and people were fooled into buying payless shoes at designer prices willfully. The power of deception is mystifying. People were walking in saying "I can feel how quality the materials of these shoes are" when in fact it was just a ploy to trick them into thinking it was better. In the LED grow light industry this deception has run rampant. I used to be that person that would sit on the forums for hours exposing and rebuttling LED growlight sales claims but found out that you are right.. most new grower would ignore the good information and just buy the "marketing" choice light ignoring the good advice... so after I while I stopped testing lights and battling it out with LED claims.. like the saying goes you can lead a horse to water but can't make them drink.
The good thing is the plants are smarter than many think and photomorphology in plants really is understudied, and in fact most plants will adapt their leaves to the light present, and "make up" for whatever lacks.. so with lighting although important even growers with CFL and house bulbs can grow nice buds if used correctly My electricity is so expensive, for me its more about my bill than the plants lol.
Great point Sativa! Oh what I would give to go back to being young and a new grower again... I had so much more energy then... LOL
