Well then. I'm about to make you happy.

It's tough to believe that little LEDs can throw as much energy into a fruiting plant as an HPS.
Yes, it is tough.
But, belief is not required, my friend.

First.
Any commercial offering that still uses 1 Watt emitters is obsolete.
Do not waste your time and money on them.
They are just re-packaged UFOs.
I have tried the UFOs
They grow bud, but not very well.

And, like you, I was skeptical 'bout leds too.
Even DIY was more than I wanted to spend.
But, we pay half a buck per kwh, so, I can't afford to run a big HPS.
I was kinda forced to try leds.
I'm just lucky that way.

The Procyon is a good unit but Pricey, so I've never had the opportunity to test one.
My homebrew lamps rival natural sunshine, but I'm not selling them, or anything, for that matter. (I is retired:jointsmile

When my first 3W and 5W emitter based units actually grew decent bud I was stoked!
The Theoreme and the Lumigrow look like good products and Old Mac uses and loves the Theoreme lights.
But, at skywards of $1000 they were not in my budget.
So, I designed and built my own and started doing side by side grows.
I've never been fond of HPS and decided that only trying to grow "just as well" as HPS showed a lack of ambition.

So, head to head with tropical sunlight.

My motivation?
Better meds for everyone, no charge.
