A 600w running at 75% is 450w or replacing with a 400w HPS is about as close to a side by side as we can get. Two SP-150s pull 270w. We all know LED runs more efficient, so a lower wattage LED should be comparable. Mars Hydro specs say two of the SP-150s are sufficient to flower a 3' x 3' space, and so is a 450-400w HID light. I'm wondering why this comparison wouldn't be fair? The wattage might not be the same, but both sets of lights would be designed for a 3' x 3' flower space, and we'll break it down to efficiency measuring grams/watt. If we need to make it more fair re: watts, I have access to a third SP-150 I can throw in the 3'x3' tent, making it 400w of LED vs 400-450w of HPS.
My proposal is to test flowering, I don't care all that much about veg, as GMT said, we know this will veg plants. I don't feel a single plant under a SP-150 will tell me what I want to know regarding their flowering potential, and I believe what most want to know. Is the increased cost of LEDs worth it and can they compete with HPS in regards to yield and product quality?
I can get an air cooled single ended HPS, ballast, bulb, socket, reflector for under $150, or DE systems for less than $400, even less with bulk commercial purchasing, so this is the big question for me. If you'd rather I don't do the side by side, let me know and I won't post it, but I'll be doing it for my own curiosity.
We should be building out a 5,000SF flower room plus additional veg in the next year or so, so this will help me decide on whether to continue to look into the LED options for commercial builds... I have a few standing offers to tour some facilities running fluence and progrowtech systems, just haven't made the time for it.
Thanks for the giveaway, hopefully I'm not stepping on any toes but I feel it is a valid comparison and very grateful.
What do you think about running three SP-150s in a 3' x 3' space with proper climate controls?
