Yes that’s the goal do I think I will hit that first run no will I try yes lol have you never seen anyone hit 3lbs a light ?
The problem I have here is you are only talking about the light. The inference is that this light reigns supreme and can make a 3 pound per light grower out of anyone.
On that I call bullshit.
There is way more to it than just a light. But over and over again we are talking about just the light doing this.
I feel like you are trying to sell me a light. Are you? Why are you not talking about media, watering, CO2 and environmental control, genetics, etc etc. What about how you weigh? Dry and Cure?

Maybe I'm wrong.
I don't even measure output "per light" although easy enough to calculate. The de facto standard for measuring productivity is based on footprint, not light count. 4# in a 4x8. Watts / meter squared. These are numbers you will see that provide a more reasonable comparison.
An even better one if trying to highlight the lighting system is KWH/gr. This encompasses an efficiency coefficient of the light.
You do you man, and if you are just a humble grower trying your best, my apologies. But if there is a sales slant to this behind the scenes, that's gonna irk me, and several others here. Not that sales are bad - but be honest and up front about it.
