Hi everyone at RIU wondering if it is worth investing in buying blackstar led lights, 240 watt or above and how many plants can they grow to full maturity?

whats the best yield people have got from a single panel? and how many plants do they actually grow with it

what method SOG, SCROG FLAT etc?


are the leds suitable for 50 plus plants?

I've just finished 25 clones under an unsatisfied Chinese 288x3W, actual draw at about 540W, it definitely cannot cover all of the plants.

BS240 draws 180 watt afaik, so i wound say 4-5 not to tall plants.

The LED grow light with many 1 watts led's and without optics are great for vegging up close to the plants
but they loose there coolness in the flowing phase when the plants are tall and the choice
is between over lighting the top bud and getting a bit light further down or keeping the distance
and not getting much further down.

In the flowing phase the panels are great use as side panels illuminating the bud from the side at very close range.

bs240 pulls 135w

It will flower 2 medium sized plants. I own a 2012 model and use it as supplemental lighting (along with other led units) for my 400w hps.

Okay, the bs in blackstar realy stands for BS, at least in the marketing department,,,

240watt Black star LED Grow Light

Even on e-bay there is more honesty.

that panel is only 9k lumens and cost 299$ why would you grow with this? my 150w hps had 16k lumens and was only 80$ shipping and handling.

Rasser I hooked my killawat up to my 2012 bs240 flower...mine draws 135 watts.

I believe you ! It's just damm I would feel cheated if I thought I was getting a 240 watt.
Imagine if it was a car engine and we where talking horsepower 240 naaa 135 to bad.

I agree with you. I did know before hand that the unit only drew 135w.

The lack of transparency in the led grow light market is as murky as it gets. Leading to questions and more questions. Its hard for the consumer to determine their needs appropriately due to all the confusion. Take simple discussions like "distance from canopy","does a blackstar really replace an 600w HPS?" , "can i get a good panel for $250 and grow bomb herbs?". :wall:
This is an emerging and unregulated market with few rules, therefore mileage WILL vary. If you buy some cheap light with unheard of claims, guess what? .....:cuss:

I have no complaints with my blackstar, yet. It does stay very dimly lit at night when powered off, no hermies yet either. Like I stated before I use it as supplemental light around my 400w digi hps along with other units. The blackstar is the only led light i bought new btw. I have bought other ones used off craigslist for steep discounts and am very happy I did. I don't think I would ever buy one new again unless it was a serious light with serious results. With all that being said I own 5 led fixtures lol :lol:

How they market the panels is tricky, It's like the car horse power example but the car actually does contain a 240 horse power engine but will only spit out 135. Which is not the same thing as buying a car that's claimed to have a 240 horse power engine but the engine is actually just a 135 HP.

What I mean is there are 80 - 3 watt diodes in a panel but they can't run at full strength which is drastically different then a panel with say... 135 - 1 watt diodes that do run at full strength. So to me personally, the marketing based off of diode capability vs wattage alone makes sense. If you just went off of wattage alone then you would be left trying to figure out what kind of diodes are in there, It's confusing either way you spin it.

Exactly, BMW comes to mind with the HP game LOL. So have your plans changed any over the past few days? Any panels that interest you?

Hey Nasar, in my experience running one BS240 the most you could get away with is 3 plants in 3 gallon bags kept in a clover pattern, and you must LST them and rotate their places once every day or two. You should get about an ounce per plant this way which is very respectable for that panel IMHO. Running a SCroG will most likely result in even higher yields. If you're looking for even more you could add some T5s and extra vegging always helps.

Wow, that's going to set you back a lil more that a blackstar 240 LOL. I just re read your original post and see your looking to do 50 plants. I also see your talking about 12*6. I will tell you right now that your going to need units much stronger that a bs240. I would get 5 blackstar 900w or some big blackdog units. Be prepared to spend 5 grand easily. Also get some light movers too.

Or a 240hp car engine with a 135hp fuel supply system.
But the question is can the LED handle 3W if properly cooled, if not then you don't got a 240hp engine.

I noted that viparled use the actual current draw to name there panels the A300 have 180 3W LEDs = 540W but draws 300W,
so it's apparently not all there is overstating.

That's not really a fair question at all because: Yes they can reach 3 watts per diode because they are 3 watt diodes but the drivers won't allow it. Most importantly, if the drivers did kick out enough juice then the cost to cool the diode would up the energy intake, raise the price or both.

My point was that there IS a difference in the size of diode that can justify labeling a panel by it's diode size combined vs power draw. A 140 watt actual wattage consumed panel using 3 watt diodes has much better penetration and growing ability vs the same wattage panel composed of 1 watt diodes so labeling your panel by actual wattage don't do much for a consumer making a decision either.

So what does help a consumer? Well IMO having both the diode capacity total wattage & the wattage consumed, because 1 without the other is meaningless.

What would be really meaningful would be the actual kind of LED used because with only the info of "1w" or "3w" there is no way to figure the best of the two. "3w" LEDs are more and more common because it is cheaper to produce a panel with 3 times less LEDs, but the fact that they are actually better cannot be proven without looking at actual technical specifications.
