Spectrum king led

[BobCajun]

That sounds intense!

Yeah it is pretty strong light, about 50w per sq ft. Whether it's better to have the cobs spread out or bunched together I don't know. Maybe they like one really bright spot, like with the sun.

i will update that though the leaves have copious resin ..the light is not making very sizable buds compared an hps

not finished yet ..bot NOT a good sign for the win

These are pretty much high bay and lot light replacements. They are replacing hps and mh lights. Those old heaters worked well, so their led replacements SHOULD work better. No surprise that they do well.

There are better options available, many of which are discussed on RIU. Free market free choice. To excersize that choice, getting informed here is a great first step.

I've actually thought about buying a high-bay LED light instead of a purpose built grow light. Went with DIY in the end though.
But highbay lights can actually be good value.

Compare Cree highbay LED
http://www.shineretrofits.com/cree-cxb-a-hc-m-160-watt-led-high-bay-luminaire-light-fixture-16-round-hook-cord-mount-400w-hid-equivalent.html
With the 120Watt vero 18 growlight from opticgrowlights.
http://opticgrowlights.com/120-watt-vero29-led-grow-light.html

The 4000K highbay Cree LED light has 113 lumen per watt according to their spec sheet. The 113 lpw is probably at operating conditions but that's just my blind trust in Cree.
160 watts is 368 dollars

The Optic Vero drives 2 Vero 18 4000K at 60 watts each, those have similar lumen per watt @25 degrees celcius.
The LEDs get hotter than 25 degrees celcius though and at 85 degrees they will be 9-10% less efficient than at 25 degrees so a few lumens will be shaved off.
120Watt Optic Vero is 330 dollar

I think the high bay lights can be very good value for the amount of watts you get.


The Cree 240 watt highbay is less efficient (100lpw) than the 160 watt but only slightly more expensive.

We forget from where we have come at times. Just go back to 2013 to see what was being discussed, the sellers and scammers and led gurls that are nowhere to be found and the supremacy of blurple.

More efficient led street lights can easily provide more light with a fuller spectrum than archaic HIDs.

I hate that damn blurple

I hate it too, really hard to inspect your plants and see whether they are getting close to being done or not. I gotta say though as far as vegging I dont think I have ever grown plants as healthy as what they were under blurple (have not grown with 5000k cobs yet...)

 

[hillbill]

I have an evergrow or vipar or whatever that flowers well but used some white and a lot of reds, kind of a light blurple, but burned diodes out also and made more heat than the a51's. Even traditional blurple makers are including white in their products and some starting to offer white or white/red options.

Okay, let me rephrase. Ambers are of less useful for plant growth than most other color bands.

I agree but only because amber LEDs are quite inefficient compared to other monos.

 

[PurpleBuz]

are ambers more or less efficient than reds ?

 

[alesh]

Generally less efficient, often by a large margin.

 

[TS-leo]

guess what the final yield?

 

[hillbill]

LEO,?

 

[J-Icky]

guess what the final yield?

By the looks of that pic and the size of the room, i'm guessing you a couple ounces of bud and pounds and pounds of trim

 

[DogEatWeedWorld]

guess what the final yield?

12 lbs

I found that my high-bays work better without the reflectors. LED lamps are bright enough as it is and have internal reflectors, the back of the chip, that give a 120 degree spread. With wall reflection that's all you need. Though I guess since you have them up so high and may not want to have to move them the reflectors may be appropriate in your case.

 

[TS-leo]

very disappointing.

 

[BobCajun]

very disappointing.

What, the results with the SKs?

 

[Djloud]

That's the Spectrum King light. Not that I recommend it.

This is what the spectrum king 400+ can do . i guarantee between 3 and 4 lbs on just the sk side. ( i have an hps side to with gavitas) and ill tell ya the sk buds are right on point with the gavitas. U cant argue with results. Oh and the sk buds are much frostier

 

[Djloud]

Albeit more expensive upfront, the SK400+ outperforms LEC/CMH/CDM per PAR Watt, and overall has quite a bit more output than the Philip's 315 bulbs. The Spectrum is also much fuller and tailored for flowering plants.

Absolutely cottect the sk kicks ass the 315 cant touch it

 

[Djloud]

You don't need a specially built lamp for growing Cannabis. The stock 4000k high bays or floodlights work perfectly as grow lamps. You don't need a custom spectrum. Spectrum Kings put out a color (CCT) of 3700k, which is the same as a warm white. The 4000k stock ones work just as well and keep the plants a little shorter, which is usually desirable. They also bring out more colors in the plants, like purples. As I mentioned in an earlier post, I would just get 240w CXB high bays because they're more compact and easier to handle than 400w high bays. You might prefer to get rectangular floodlights though, since you said you wanted 120 degree beam. A 200w one would have two 100w COBs in it. Any color from 2700k to 4000k is usable for plants, 4000k being the most commonly available.

The sk dont use the same color leds i believe its 4k with some 660s and far reds. Its really a FULL spectrum. The light will rock out a 4×4 and penetrate better than any hps. I have a light meter and the sk beats the gavita all around. And im not bias aginst hps i love my gavitas. But these sk s kick ass flat out. Once again u cant argue with real results. The pic is week 4 all sk. Rockin the house
