This really isn’t an argument anymore, modern LEDs absolutely slay hid in every category. You can look at very detailed spec charts for any variety of LED out there and see the numbers for yourself. Way more light per watt, way better spectrum, equal or greater penetration, great coverage, not to mention way less heat and generally easier to use.
Here’s a guy whos set to harvest 9+lbs of top shelf weed from ~2000w of LED light.
I say this as someone who runs HID lights myself because I have so many laying around. I’d switch to LED in a second, and will over time as my equipment gets old.
Costwise a quality LED won’t cost much more than a comparable HPS and will last 5 years easily (with no bulbs to change vs a new hortilux once a year on HPS). Not to mention the dramatic savings in energy costs which will usually pay for the light itself completely over time.
