Hey I dunno....I'm just guessing too. So ask your electrician buddy to bring over his clamp-ammeter (I think they all use them) and plud in your 240W Blackstar and see what it reads for amp draw.

Im going to crack it open and see what I can see tonight...pics tonight...I'll have the ammeter done by or over the weekend. I see him frequently enough. Im eager to see, im going to test my 240W and my 500W see where they fall.

I got one this summer for $20 shipped to my door, on ebay.

took pics...Blackstar has a solid metal heat sink (or a thick enough piece of sheet metal, about 1/4" not flimsy) That is sealed to the casing using what looks to be a silicon sealant. Thats about as far as I am willing to take it apart. I was hoping that plate would be mounted differently.

sorry 120 degrees. growth so far of seedlings is impressive. 90w ufos are from sunlightsolutions. the 357 sounds interesting. how long did it take to get?

I've never done from seed but clones definately do really well under the LED's. I really do feel that the light is more tuned in for them and there is not nearly the radiating heat and UV and they don't get stressed. You will definately see the most lush green plants you've ever grown. With 120 degree lenses the coverage area spreads out very quickly as you get farther from the light so you need to keep them close. My ISIS panel I use for the clones is 90's and 120's and I personally find it is great for short plants but because of the lens angle it lacks penetration when the plants get taller. There is a guy on here LedBudGuy who just used the ISIS panels to do a confined space grow and he had his lights almost on top of the plants and his plants were only about a foot tall and he got great results. 762 grams from 850 watts.
My 357 was actually at the local post office 7 days after I ordered it but the post office didn't drop off a delivery notice so I didn't get it for another 3 days when I finally just went down there to check. Seeing as how that was in the Christmas Parcel craze I'd say that's pretty good time.

Oh yeah and a sneak a peak at the next generation getting started. They were rough when I got em as it was an order for someone else who didn't pick em up so they sat around for a week but they are bouncing back fast under my ISIS 170. Purple Kush is gonna be the next run

They look to be thriving under those monsters. I added a 1600 lumen ( 23w) cfl yesterday to the box and moved things around a bit. Temps were running low ( 72) in a cool underground location so I thought adding a bit more light and heat wouldn't hurt. Temp now hovering around 78 so I think that did it. Humidity still at 35-35 rh Also bought a 60 w grow spot if I needed more heat but think its good now. Really interested in how ur bad boys 357s do with flowering before I order one. My widows are growing great with the two 90 w ufos, ( tons of roots hanging from pots- the carms are lagging ( re seeded two spots) and the freebie wild cards are slow as heck. Plated a few more and put them in the pots yesterday. Made a few mistakes as the roots came up and got cooked under lights. Tansfered the slow ones into my cloner/seeder chamber to see it hey ever do anything, just hoping the plate started seeds give me a few more options with this first hydro grow. pics will be up later in my post.

Haven't converted my thread to journal yet but will today and post pics. Using the 14 pot system as supplied by sunlight solutions with my ready made cool cab. Has drip. Dogger and deep water roots are already into for the widows. No shortage of water.
Journal finally up with some pics. Widows are thriving

Well another round of pics an pre-flowers are clearly visible. Plants are super healthy. Took one pic with the flash on to get a feel for the green in natural light. Also snapped a pic of the inside of the 357 to see the heat sinks. There is six fans in it.

Not trying to hijack, But this is one of the first true LED grows I've seen done right and I love it! In fact, I just ordered a .357 Magnum and can't wait to see the results. Thanks for giving me hard evidence to put my LED worries to rest.

What style you gonna grow? The only thing I will say is that these lights are totally tailored for a person running a few tall plants. For sea of green or scrog I would go with the ISIS. These lights have huge penetration and it would be kind of a waste on short plants. If you wanna see an LED show done right you should check out the Confined Space Master Kush Grow that was just finnished a couple weeks ago by LedBudGuy. He used ISIS lights and it was very impressive

You have 6 plants under each panel? What is the 'footprint' of each led panel, in your estimate, or in your room? 2'x3'? Yours are the first LED lights that actually look like 'bright light', so I am anxious to see the results in terms of height of plant, penetration, and yield.

I'll give you a short run down. When all three rooms are done I'll start a journal with pics. For now I'll be running 6 Power Plants in a 5x5 secret jardin room with 1 .357 magnum on a mover and a CAP ebb n flow with STG and all Advanced Nutes. I think with the PP's Size, this light will be perfect. Whaddaya think?

I think "footprint" is easily one of the most misrepresented statistics in the lighting industry. I grew with HID for about 12 years and I remember the advertised "footprint" of a 1000W HPS was 10ft by 10ft but pretty sure that was for growing lettuce . Personally I found anything bigger than a 5 ft diameter circlular area, or about 20 sq ft, and the intensity wasn't there for a decent crop. My favourite light to grow with was 600's. Used to cover about 15 sq ft with them and get about 15% more yield per watt than running 1000's. I also used to run more of them and get lots of cross lighting which really helped. My old room design was based on 4x1000hps in a 10 ft by 10 ft room. Used to run two of them on a flip-flop. When I changed the rooms to run 6x600HPS my power use dropped 10%, 3600w per room vs 4000w, and my yield went up 5-6% so way more efficient. One of the things I love about LED's is that it's not a single pinpoint of light so there is less chance for shaded areas on the plants.
So to actually answer your question. The 357 Magnum is covering the same area, and doing a better job, than my 600HPS. Time will tell but I have been messing with LED panels for about 2 years now and this one really has intensity like nothing I've seen. Right now there are 6 plants under each light but they are only just triggered and this strain will double in size so I will end up covering a much larger area near the end. I could cover at least 9 of the plants with one light right now but I need heat in the room and I am a big believer in interlacing or cross-lighting so I fired up both

Skip the light mover and just stick with simple GH nutes and with the money you save pick up a second 357 and pull down more bud
Haven't tried Power Plant but was just researching it and sounds very interesting. I'll deff watch your journal.
