lol seriouslyNo offense, but this thread has gone from talking about commercial lamps not being cost-effective, to making heat sinks out of aluminum foil and steel wool. Holy Fucking Shit.

But they're amazing, aren't they?I like thinking outside of the box too. The problem with steel wool is it's woolly. What we needs is a cohesive conduction path, from the chip to heatsink to radiators. The steel wool would probably act as a thermal insulator, if anything.
Dear God wtf is that, 3D printed aluminum? If it's a continuous extrusion it could have physical cohesion and with such massive surface area, a great deal of thermal radiative capacity. Sounds almost like I know what I'm talking about....But they're amazing, aren't they?

Yes I see that Bright Light LED logo on their cubicle window. Looks likely that SK is a front for BLL, re-marketing high-bays to the grow-light market. Better if they marketed up front. Their approach is obviously, um, cheap and cheerful. The lights might work well for a specific application though, I don't see why not, especially if thy have tunes the diodes. But I don't appreciate snake-oil marketing trickery. So they trot out this hippy guy to make it seem legit. It's marketing. Do the Chinese think we're stupid? BUT they offer a UL listed fixture that looks pretty beefy in a price class that seems relatively competitive with other offerings in their wattage range (which they do at least state up front). I can see these being useful for high-bay greenhouse supplemental lighting. Nothing to get too excited about, but not total trash either.Check out SK's video at the 6:04 mark.... Look at the window in the back... what does it say... (Bright Light LED)...
I believe that they are still Bright Light LED.. But selling the Spectrum King as their "brand" of grow light. As far as the Cree endorsement goes.. I'm just guessing on this one, but I can't imagine Cree backing a product/company making false claims about their product. Doesn't make any sense to do that. Especially for one of the largest chip manufacturers in the world.Hey everyone... been a while since I've been online but came across this thread. I didn't see anyone mention this but wanted to share... I agree that SK is nothing more than a "slightly modified" high bay light... and I think their claims are definitely inflated as most LED companies are...but that's not the reason I'm posting....

So then I googled Bright light LED and came to their website which is BrightLightLED(dot)net....
And sure enough, Bright light LED is a high bay and commercial application light supplier and what looks to be manufacture...
Then I went back to the video and watched it, and noticed that everything in the video that said "spectrum king" was just printable marketing materials, signs banners and stuff... where the actual window on the building said Brightlight.... seems very fishy to me...and very similar to my days in the hiphop industry..(rent cars, jewlery, girls, film and shoot videos and photos to make it "real" and then send everything back)
So it looks that SK is basically doing what other LED companies are doing... swapping a few diodes out, and calling it the best new things since sliced bread... Does anyone know how they are affiliated with Bright Light?
One thing that did puzzle me is their "cree" affiliation through spectrum king... they actually are listed on cree's website as spectrum king, but not as bright light... anyone have any insight on this? is it just a paid endorsement? I thought official cree vendors had certain standards to operate by so is SK just riding on Brightlights 30 years of lighting products?
Just thought it was very interesting and wanted to share it here....by the way I personally cant stand the guy on these videos...

But I could be wrong..
Not steel wool, aluminum wool. But yeah, it started as a Spectrum King gripe thread and gradually turned into a general DIY thread. Getting back the the topic, I've read reports of 850 grams from a single 400 watt Spectrum King so they apparently do produce satisfactory results when used properly. May not be as efficient as DIY cobs but for out of the box units I'd say they're as good as any and better than many.No offense, but this thread has gone from talking about commercial lamps not being cost-effective, to making heat sinks out of aluminum foil and steel wool.

It's not actually a chronicled grow. It's a comment on a YouTube Spectrum King video. Look for Yuck Fou on the second page of comments. Doesn't sound like a shill to me but I suppose it's possible. They have another video where they got an independent dispensary to grow it and they got 700 something grams in one and 800 something in the second.You got a link to that 2gpw grow?
I'mma go out on a very skinny limb and say YouTube comments may not be the best source of reliable information.It's a comment on a YouTube Spectrum King video.
No but it's all we got right now. They gotta be at least as good as a 400 watt HPS, without the massive amounts of infrared beaming on your plants and burning the crap out of them. Also nice and quiet. Costs more, yeah, but quality costs. HPS are just incredibly crude compared to LEDs, even just rebranded high-bays. But, yeah, I'm pretty sure Spectrum King is just that one dude drop shipping BrightLight products with a Spectrum King sticker stuck on em. It was a pretty good idea for a business though. Gotta give the guy some credit for creativity. At least they're domestically made to US standards, instead of cheap Alibaba ones made from duff LEDs that only a small percentage of actually light up. You wouldn't know unless you gradually increased the current from zero to full, because you obviously can't look at the powered up high-bay to see which LEDs are actually lighting up.I'mma go out on a very skinny limb and say YouTube comments may not be the best source of reliable information.
That is rich. Yuck Fou sounds like a Chinese high-bay manufacturer dude with a dry sense of humor and a good command of viral marketingIt's not actually a chronicled grow. It's a comment on a YouTube Spectrum King video. Look for Yuck Fou on the second page of comments..
Perhaps, but why would he say he got slightly less than a 1000 watt HPS instead of saying he got slightly more if he was making it up? You should be able to get as much as the DIY lights. It's all LEDs. They just run the DIYs at lower currents for higher efficiency. But what if you simply used a LED wall dimmer switch to dim the SK light to maybe 75-80% of normal current? Should get similar efficiency. I've seen people reporting 2 g/w with DIYs so it's theoretically possible with the SKs. They have the same lm/w output. The light isn't spread out as evenly but maybe it doesn't need to be. You might get more yield under the middle and less at the edges but it might average out the same overal.That is rich.

I've seen 1.4g/w from LEDs but I have yet to see evidence of a 2g/w grow with anything. I said evidence. I've seen about as much evidence for 2g/w as I have for proof of God's existence (said the atheist, baiting the theists for no reason) - I'd love to see a mildly convincing grow journal of 2g/w out of any system.Perhaps, but why would he say he got slightly less than a 1000 watt HPS instead of saying he got slightly more if he was making it up?

Actually top bin xbd will not produce the same amount of light/photons per watt no matter how low you drive them vs a 40% or higher efficiency cob. Also xbd probably isn't as efficient as hps in a really good reflector. I'd have to see a SK light produce anything over a lb to believe it.Perhaps, but why would he say he got slightly less than a 1000 watt HPS instead of saying he got slightly more if he was making it up?

You may be right. DrJ 303 on YouTube only got a pound in his SK test grow. Still, 1g/w is more than I ever got with a 400w HPS. I got 150-200 tops with a good hydro system. I didn't have a very good reflector though.Actually top bin xbd will not produce the same amount of light/photons per watt no matter how low you drive them vs a 40% or higher efficiency cob.

Growmau5 got 1.83 g/w from XM-L2s mixed with CXAs. The title of the video says 1.5 but that was just the best buds. It says 1.83 total near the end of the video. Good DIY build tutorial btw. The high yield may be due to adding some pure red LEDs. Might be something worth trying. He did also put 2 blue ones in there but I can't see those making much difference. He had 10 reds in there and only 2 blues. Should have just put 12 reds. I think the reds are the key to monster yields. Unfortunately, he said the colored LEDs pooped out about halfway into flowering but they may already have helped in setting the buds up. I guess that means the second half of flowering was under less than 285 watts, more like 250. So with a yield of 521 gm good buds that's over 2 g/w.I've seen 1.4g/w from LEDs but I have yet to see evidence of a 2g/w grow with anything. I said evidence.

I totally forgot who got 1.8, thanks. I didn't want to say it until I re-verified. Hooray for Growmau5. I think someone else here was in that range too. I'm just asserting that 2g/w is still the holy grail, and it isn't something people are doing regularly with any gear, if at all. There's probably a couple cases of it, but that's a tall order. My gear is pretty ghetto, but I'm happy with .5g/w of fire so far. I'm working on improving that, just competing with myself. Will have some COBs in hand next week. Why mention it? Because I'm having so much damn fun! Sometimes I feel myself falling into competition mode, then I remember I don't give a fuck.Growmau5 got 1.83 g/w from XM-L2s mixed with CXAs.
