I just ran over the numbers a few posts back. 35w sq ft for LED 55w sq ft for HID. No led is not more than 200% more efficient than a HPS.
Yes they do work just overpricedThanks Moshmen, I'm looking but it seems to jump up from 120w to 240w which might be a bit much? And for the area did you mean TS model as in the Mars Hydro?
What light of yours would replace a 600w hps just doesnt seem worth me switching to led, yet
Cheers for thatSorry I was a bit short on that answer. I'm at work driving (on a break now).
Led seems to be around 140% that of HID. Roughly. Obviously there is some variation due to led manufacturers and efficiency ratings.
Best case is 50% more. So a 240w led is more equal to a 400w hps. 2x240w would be equal to like 800w etc.. rough numbers of course.

Thanks for that. My mate supposedly had a high end led with the lm301 diodes or whatever, had good results as far as yield and quality but just seemed like they didnt perform as far as growth rates compared to the hps, also heat is generally helpful especially as I run my flower cycle at night I dont have to add additional heating
Yeah most likely, so what can you expect average gram per watt for led or what do you get? As they say with hps gram per watt is decent can be more or lessI'm willing to bet the led he has is nowhere near enough wattage to be the equivalent of whatever he replaced. I have the opposite experience. HID doesnt hold a candle to the LEDs I run.
At least a 450w LED grow light. Usually for LED, 30-50w per square foot will help you get decent results, and more watt, more results under the same conditionWhat light of yours would replace a 600w hps just doesnt seem worth me switching to led, yet

I haven't used for weed yet but I've been crazy happy with my tomato & pepper starts, nice short stout non leggy growth almost pencil thick stems, so far so good for 200w, nice small footprint.I'm picking up a SF 2000 this fall. My friend swears by them. I've seen his ladies and they look very happy.
The level of spam/hype with them is irksome IMO.Mars had a terrible track record of customer service, but thinking MAYBE they have improved their products, so...
Out of curiosity does that pull 240w in real time?Kingbrite 240w quantum boards are pretty much the exact same light.
240w mean well drivers and lm301 chips. Kingbrite's heat sink is much nicer, and it is dimmable. All for only $105.

There are many of us running kingbrites now, not a single complaint.
Hope this helps man!
Yeah @MIGrampaUSA did a kilowatt reading earlier in a different thread and it read 243watts.Out of curiosity does that pull 240w in real time?
I have a spare bedroom with a 48"x36"x72" tent, I've been humidifying the hell out the tent for tomato starts and its wreaking havoc on wood in the room, started running fans outside the tent to dry it out, I have a door closet that I hadn't looked at until a few days ago, a couple huge pillows were actually wet & molding off the wall, I may have to get a dehumidifier for the room to prevent further damage but the humidity levels will go down when the the starts are out & the meds begin.I envy those of you that can dedicate entire rooms to it, I've never grown in anything bigger than a walk in closet
