Yet more evidence that a full spectrum LED light source is better for plants.
HID, the bell tolls for thee... it's only a matter of a few years before newbs start asking us old timers what it was like to grow weed with light bulbs.
There's no more incandescent in home lighting to speak of, it's all CFL or LED now. LED is ready to supplant T5 in gardening, now it's the big bulb's turn.

Well said, I have a small clone dome setup with a little 18in T5. I use a LED flood bulb instead and get better results. Its minor but I notice an improvement.

One of my Sensei's is telling me that no commercial grows use LEDs. Not exactly telling me in the spirit of good Christmas cheer today either.

Geez guys. I need to get off this thread. Thank you @robincnn and @Stephenj37826 for your help - My inexperience with LEDs kind of confused me - the Bridgelux show up as the highest Lm/W but they aren't the highest output. The Samsung look like they are - which you already knew. Thanks again!
I'm gonna keep crunching these tables to find the cheapest configuration.

I believe the quantum boards may help a bit with the hotspots compared to the 3590's. Time will tell in penetration. 4 quantums replace 8 3590's. Same total wattage.

Interesting, for me 8 boards pulling 670W replaced 16 chips totalling 900W.

If you notice Digikey uses different data or maybe interpreted data. Bridgelux lists with 25*C, but Digikey data based of 85*C

So you would say these boards are each as good as over 2+ 3590s?

Depends on what you're defining as good.
A bit better PPf/W, great LED spectrum, much better heat dissipation, lenses help performance.

I am running 8 3590's beside 4 quantums at the same wattage. 75 per quantum, 37.5 ~ per 3590.

I was switching to 3k Vero gen 7 as I like them better than my 3500 3590's. ymmv Then these come along. The spectrum is very close to the Vero, more lumens per watt. So I ordered the other two drivers today. They will work with the new veros. I think I'm sold. I just flipped.

To do a fair comparison in my case, I should match wattage. Easy enough to do; 3 x 225W COB LED modules = 675W. That's next, and then we can have some good comparisons.
