    So, I’ve been interested in these new led’s.  I’m naturally a non believer when it comes to led’s because of there lack of intensity and small spread.  But Spectrum King led’s puts out a 6′ by 6′ with greater PAR than a Gavita 1000 DE without the heat.  Also a spectrum that compares to the sun with a natural light color.  Way easier on the eyes. The company is so confident in there light there doing side by side grows in one room that’s partitioned off.  All the same age Blue Dreams. With all the major bulb competitors in the mix.  There still in veg. and a have two video’s out on you tube.  They are definitely in the lead with the Gavita’s at a close second.

    What do you guys think?  I’m getting ready to purchase lights and am seriously thinking about going this route! https://www.youtube.com/channel/UC6-oUK6yEFQ1EP-DhiWG4jA

    I think that iIt is going to take a few years before leds are to be at their best. Even kyle tried leds and didn’t had good results.

    Black dog LED is the best and only brand that is legit. They do guarantee 1lb with most strains. I have seen them in action and they are good but price is bad for initial investment. Also they do put off quite a bit of heat that has to be counter acted somehow. But they say even though room maybe a little hotter, the surface area on lead is actually cooler than with the hps.

    There’s really nothing conclusive. They sell their salad(their product) by saying that these leds will get you a heavy harvest but there is not really conclusive photos (budshots, micro/macro shots). But I’d be curious to see a final result made by kyle and/or braveheart.

    Well I have seen the buds from a grow using blackdog LED and it is pretty impressive. If I was buying a new light I would seriously ponder. They say they personally guarantee a lb a light because the internode spacing is so close together, the internal plant temps are cooler causing less stress on plant and growing faster, and the spectrum. It is American made too and can be repaired boulder co. Anyways I would say its the LED light people have been waiting on and worth considering if you got the money.

    Hello Everyone

    @greendream I have had my eye on this company for sometime now the old company name was Sunlight led now known as spectrum king I’ve seen all the videos they have posted that I’m sure you watched also. I personally have yet to see the lights in action but from the videos they look promising and i hopefully will get to see the lights in person soon when I travel to California to the manufacturing facility. I will re-post my full opinion when I see the led’s in real life and can touch and feel the light and heat created!

    Have a great growing day with a feel good vibe!

    Hello Everyone,

    @greendream, Looks like you have seen the specs and I have spoke with the owner of Spectrum king Ronnie and I will be making a stop by the manufacturing facility sometime around Dec 19-23 to see them in person and feel the heat and hopefully get some readings of my own from an unbiased source. I will be posting my results and opinions when I get to the shop. I’m very excited that they are going to let me come and see the lights in action and also their side by side test room!

    Have a great growing day with a feel good vibe!

    Spectrum king is no good dudes. Black dog is the IT product in LED. Spectrum king wishes they had the technology black dog has.  Black dog has 15 spectrum plus ultraviolet. I have seen plants grown with these and if I already did not have my set up, these would be what I would buy 100%. It’s American made and repaired here in the states as well if any problems arise. Others have to be shipped to china generally or replaced.  Lifetime warranty. Y’all research it, they are top notch. Fat buds all the way down the plant from what I’ve seen with super trichomes production.

    Hello Everyone,

    @driverinthedank

    Have you personally saw the spectrum king in action or do you know that one of the “other” lights used in the test grow is very very close to the “old” style of colored led and very close in comparison to the black dog. I’m still 50/50 on led’s. Also all of the  products that spectrum king uses is made in house at their California location even down to manufacturing the led cluster and driver. They also stand behind the product 100% and post “real” grows not fruit and veg. I will be trying to set something up with black dog here near me in boulder to see their product too!

    Yes I have seen them in action and they are simply amazing. Can’t beat a lifetime warranty either. And it is the only company that guarantees a lab per light. And it sounds like your information about the old lights being used like in black dog lighting, that is straight up false knowledge you have. That’s why they can guarantee and warranty the way they do. I’m near boulder and I have seen the gardens with them and other than price, they are legit.

    Hello, @Everyone

    I just got off the phone with the guys over at spectrum king lighting and they invited me up to check out the lights and to see what they have going on out here in California! I’m excited to report back everything I find out and will answer any questions that I can and maybe a demo product!

    Hello @Everyone

    I’m excited to say that Spectrum King was more than welcoming when I went up to visit their test site and build shop! They have a lot of great things going on and their lights are totally the real deal in new led grow lighting technology. The spectrum and penetration is unlike anything I’ve ever seen before, it is by far the best light I’ve used or seen in my grow career!

    As Always LightSpeedGrows,

    Have a great growing day with a feel good vibe!

    Hello Everyone,

    Thought I’d share these videos too they were shot today at the spectrum king test site. Feel free to leave any questions or comments below. I can’t express it enough how excited I am to test the sk-400 over my TGA cross of Dairy Queen grown with Vegamatrix!

    As Always LightSpeedGrows,

    Thanks LSG for all the cool pictures and video’s! Ive puchased 4-90 degree angle Spectrum Kings for a 10′ by 10′ Gorilla tent with a 9′ ceiling. I’ll see about starting a grow journal. I’m getting back on my feet so to speak. So, it might be a little while. I’m currentlly running one light over 9 plants in 10 gal. pots in 5′ by 5′ square corner of my tent and am very happy with the growth. None of the plants are suffering from lack of light. They run very cool and still have great brightness! I can’t wait to start some veganic flowers going under these lights.

    Hello GreenDream,

    First off thank you for the kind words and I’m glad to hear you are staring to get back into the swing of things, it took me some time and research to gather all the info and once I felt there was enough proof behind the Spectrum King SK-400 I gave it my stamp of approval. I’m very glad to hear that you chose to go with 4 of their SK-400 90 degrees lights. I know that it was a decent amount of money to drop on 4 lights but you will love the zero maintenance, super long life and minimal degradation in lighting quality!  That is really great to hear that you already have been seeing great results with one and I can’t wait for you to brag to me and everyone else how great your garden is doing with all 5 of your new Spectrum King lighting LED’s! Also one last thing I will be in the next day or two starting a new thread just for all of us LED grow guys to share and educate. I would love to see your input on this new thread if you feel like sharing!

    As always LightSpeedGrows,

    Have a great growing day with a feel good vibe!

    actually I’m not the one who bought the spectrum king lights. i am waiting to see and hear results myself. i only know of and have seen the black dog led lights. which i highly recommend except for the price point. but I’m glad i see whats going on here, cause i might have to purchase myself. I’m not a fan of the test in the above video. this is why, the hps lights have to have heat moved away from the site or it will create airy buds. if one has heat sucked away from lights it should be a dense as the others. i have tested this personally. density is all about lumens per square foot, genetics, cool/hot room, cool/hot nights, feeding ect.  so in the test rooms i didn’t notice or it didn’t look like the heat was being moved away properly. looks like its just being pushed around. so with the led burning cooler then that would be reason for more density. thats just one issue with the video.

    Hello Everyone,

    What you can’t see is the 4 A/C wall units mounted up high and the temp was very even in the room and lots of air flow in and out. I was there personally and the room felt very nice and even no hot spots even under the 1000w. The test room they built is solid and I personally saw no flaws. What they tried to do with this room was to show what it would grow like if you just bought any of the random lights used and a clone from the store. They did nothing special to any of the plants besides tying up the buds at the end they tried to replicate a new grower that chose a light and went for it with little knowledge. I’m personally testing one of their lights right now and my two girls that are under it are loving it the only thing I’m worried about right now is with 1 month of flower left that they are out growing the room and getting so tall they are super healthy. I have seen one other grower using this light and he let his bush come about 5″ from the lens and he said it did just fine so i guess I’ll be finding out.

    As always LightSpeedGrows,

    Have a great growing day with a feel good vibe!

    Not sure if you’ve purchased your Spectrum King or not, but as an owner of one, I’d recommend against, and here’s why.

    Spectrum King vs the competition. (Magnum 357 and Diamond XPS 150)

     

    Let me start by saying that I really like the Spectrum King. It’s sealed, and has no fan or moving parts. This is a huge plus for anyone who needs their grow to be quiet for stealth (or just because you don’t like noise.) It’s also cleanable with water, which could be a huge plus. Not dust or resin inside. And also no bugs inside! The Spectrum King also has a very pleasant light. It looks like sunlight to the eye, and feels like sunlight on the hand. I liked the promo material/videos for this light enough that I bought it new from the manufacturer. The other two lights I purchased used. If I had to sit in a grow space all day, the Spectrum King would be the light I would want to be used. The other lights, particularly the Magnum, are very funky to look at, hard on the eyes, and make assessing plant condition more difficult.

     

     

    Let me first point out flaws I am aware of in the testing methods used.

     

    – First, each light got a sample size of one. Though clones from the same mother, genetic abnormality could be at play here. From a statistics stand point, this might be the most significant flaw in the test. However, the throw of all three lights is not sufficient to flower a larger surface area than I used in my SCROG. Each light did approximately 6-7 sq feet, with some overlap. (see below)

    – Second, all three plants were grown on the same screen, in an industrial rack that is slightly larger than 6’ by 2’. The SCROG growth ended up being about 3 feet wide and 7 feet long, as the plants tend to hang out of the defined space. This should have given the Spectrum King a slight advantage, as it was the middle light. Each of the end plants got their assigned light, plus a bit of bleed from the Spectrum King. But the middle plant got the full Spectrum King, and bleed over from lights on BOTH sides.

    – Third, the Spectrum King was 4” higher (22 inches vs 18) than the other two lights, as measured from the glass. The inverse square law indicates that it will of course have somewhat diminished power if further away. However, I placed the lights at the manufacturer’s recommended minimum distance, and the Spectrum King has the highest rated light wattage (and highest draw at the wall.) My e-mail requests for clarification of the height measurement (glass vs LEDs) were unanswered by Spectrum King on installation, so I measured to the glass. Measuring to the LEDs would be difficult due to the shape of the housing. In the interest of fairness, I lowered the Spectrum King slightly to 22” vs 24”

    – Fourth, the Spectrum King was new out of the box, the Diamond was used, but the “current” version, and the Magnum was used, but one version behind. (Should have been another advantage for Spectrum King.)

    – Fifth, it is possible that the Spectrum King could flower a larger area if raised up (thus getting more bang for your buck), whereas the Magnum and Diamond clearly would not. But, the manual for the Spectrum King indicates a flower illumination of about the size I used at the specified height.

     

    Those are the only significant flaws I am aware of. All other conditions were identical. Thus, even if the conditions weren’t ideal, they were uniformly not ideal and should have provided a good baseline for testing the lights.

     

    I will also mention that the spectrum king has all 200+ LEDs in a puck about 4” square, vs the other two lights having their lights spread out over a much larger surface area. It seems that that would make it brighter in the middle, dimmer on the edges, and cause it to cast more shadows; perhaps not giving as uniform of illumination as the other two lights. However, there was no noticeable difference in bud formation or plant height over the entire area of illumination, so it seems the reflector is doing its job very well. Additionally, at ground level, the Spectrum King was the only light making significant penetration to the soil, and even to the floor below. It is entirely possible that SCROG is the kind of grow least suited for Spectrum King, and that it would/will do better in a regular vertical grow.

     

    I will not claim to be a pro, as this is only my 5th grow, but I have a very green thumb. Spent my youth farming, and manage to very successfully grow more than 100 species of plants in my yard in California. I get plants.

     

    Summary: In my grow, the Spectrum King just wasn’t cost effective. Not only was the Spectrum King the most expensive to operate in terms of power consumption, it had the highest MSRP and produced the lowest yield in my test.   (Your growing style/technique may yield different results)   I was hoping for superior results, but could have lived with just equal results because of the light’s other advantages. This was a huge disappointment for a light I really wanted to love. (Because I do spend a lot of time in my grow room, and hate the purple light the other lights put out.)

     

    All wattages were measured at the wall (using a Kill-a-watt meter), and bud weights are dried and trimmed.

    The Magnum 357, drawing 334 watts, produced 210 grams of dried/trimmed bud. (0.63 grams/watt)

    The Spectrum King 400, drawing 491 watts, produced 175 grams. (0.36 grams/watt)

    The Diamond XML 150, drawing 148 watts, produced 220 grams. (1.49 grams/watt)

     

    The huge surprise here was the almost 1.5 grams/watt produced by the inexpensive and low power Diamond XML 150. In addition to being the most cost efficient, the diamond also has two dimmer switches, allowing the greatest versatility in light output. It runs amazingly quite compared to other LED lights I’ve used as well.

     

    We did not weigh the trim from each plant separately, but we got about 170 grams of sugar leaf trim combined (dry weight). That’s a total weight of 775 grams (27 oz / 1.7 lbs). So, an average of half a pound per plant. I’m pretty happy with that.

     

    A last note about SpectrumKing. Bigger than the disappointment in my grow was how SpectrumKing treated me when I asked to return the light. Their sales lead (yes, Brendan from the on-line videos) said my claims were unbelievable, and when presented with my grow log and final weights, simply stopped answering my e-mails. Diamond offers a 90 day risk free guarantee, which is long enough to flower plants and see how the light performs, and a 3 year warrantee. SpectrumKing, on the other hand, says they want you to be “completely satisfied with your purchase” yet offer only a 30 day return window, which of course is not enough time to see how it handles a grow. I was outside the 30 day window (obviously) by the time I harvested, and didn’t necessarily expect them to take the light back. However, their rudeness came as a bit of a shock, and they clearly don’t really care if I’m satisfied or not. It’s great to be proud of your product, it’s not so great to turn a blind eye to any information contrary to what you’d like to believe.
