I run a comparison of 4 LED types in my thread, all 1kw HPS equivalent/replacements… 16SF per light, generally shoot for 30-35w/sf
Here’s a post with apogee measurements for each and more info generally throughout the thread: LouDog's LED Lounge - #17 by LouDog420
Growers Choice ROI E-720
Grow Light Science Progrow 850
Total Grow MH Lumyre
Spectrum King Pheonix 680
All in the $600 price range… Plenty of good options for that $$$ these days. IMO, buy once, cry once…
Definitely still a time and place for old single ended 1kw HID when you can set up a space for $150 worth of lighting and rock vert tree setups. But the LEDs are nice. Just make sure you up your feed concentration (feeding 2.5-3.0ec these days vs half that under HID), and run higher temps to push transpiration without the radiant heat of HIDs…
