Spectrum King SK602 opinions?

Anyone have any thoughts on if these new Spectrum King’s are worth the $1500 price tag?

I didn’t realize the height restrictions. I’m in a 10x10 tent so this might not be an option. I am curious to know if I could shorten that distance by having them rotate on my light rails. I’m currently running 1000 watt HPS on the rails with about 12 inches of clearing from the tops of the bud sites with no issues. Think the Kings would work with that setup?
 
There is a ton of options out there these days. I want some good quality. Right now I’m running the SolisTek A1’s 1000 watt HPS lights. They work well on my light rails.
 
SK600 has been measured to have an efficiency around 1.6 umols per watt. Thats better than your typical standard sodium discharge lights. And comparable to double ended sodium discharge which has around 1.7 umols per watt. So its efficiency is not to fault. But its price may be. There are other products out there currently that close on around 2 umols per watt at around the same price or less than that of spectrum king.
 
Thank you for the advice. I’ll definitely have to do some more homework. I’m looking for more efficient lighting without losing quality and plant productivity. COB lights had me curious as well. Seems a handful of growers are trying these out. Lighting is not my strongest suite when it comes to growing. And these days you can rarely take the advice at the local hydro shop.
 
Nextlight, chil LED and rapid LED are the only manufacturers i know that make a product with an efficiency equal to or greater than sodium discharge. ​​​​​​​​​​​​​Paracelsus and RosettaStoned were avidly looking into efficient LED products, maybe they might know more on the matter.

Perhaps look at my artcles on light technologies also.
 
Oh also spectrum king sk602 is the new model which is slightly more efficient than their previous sk600 model. So i would also add it to that short list of products.
 
Cannabis plants will not notice the slight difference, but your wallets will. Cannabis evolved for the light of old Sol for millions of years,and that star and has never charged me a shekel. And besides cannabis cannot read spec sheets. Content in my unsophistication.

Great job you are killin it! No need to change if you are cropping like this with only 2000 watts. Those light rails and your proven hid technology is putting $$$ in your pocket and that's a testament to your growing talent and choice in equipment.
 
I have begun to understand more about COB technology. Spectrum king, CHILLED, Rapid DIY and other cutting edge LED manufacturers focus on different types of COB LED. They are very efficient and have high uMOL ratings directly below the light. Each lamp has a limited foot print so the most efficient and brightest have multiple lamps. I was first attracted to the spectrum king lights but after further research I decided unless it was for seedlings or clones it just didn’t have enough diffuse light for a large footprint and the bang for the buck just wasn’t there. The CHILLED have the lamp spread out using a quantum board and integrate a great cooling system but again the start up cost is prohibitive. What I have decided is best for me is the rapid DIY in combination with a quantum board DIY but rapid also sells completed light fixtures. Grow mous5 Who works now for chill LED made a series of videos explaining the technology for DIY that he and greengene on YT explain and discuss. They also tell you where you can source all the different parts to DIY yourself. Grow Mau5 just last week ran a new video with a new COB design that includes blue, red,and far red spectrum LED 5 W chips Incorporated into a round COB, this is what I’m going to say is the cutting edge right now. A combination of these lamps with the DIY rapid kit and a quantum board is where I’m headed.

That said in the last month I bought 6 HPS Ballasts, a 4x 48 & a 8x48 T5, 3 sun open hoods and a light rail along with 2 150w grow light lamps and fixtures all for $675.
there are bargains out there now from all the people who are upgrading. That’s how I’m starting out there is nothing wrong with a good HPS fixture with the good bulb in it. If you look at a side by side video on say Vader‘s channel you’ll see a 600W HPS right next to the chilled LED running neck and neck.The LED has more frost though because of the spectrums. Remember 600 W is 600 W, you are still using the same amount of electricity perhaps one will be cooler than the other but perhaps not enough to see a return worth the investment of a high-end LED.

It makes total sense. I appreciate the advice and in-depth explanation. Was it difficult to assemble your own light setup. I mean for awesome lights like that for under $700 is pretty impressive. Now the reason for wanting to switch was to try and draw back on the power usage. Not a huge deal but in all reality like you mentioned 600 Watts is 600 Watts. I do love the HPS and it definitely helps keep some heat in the tent. ( I live in Alaska so heat is a good thing.)
 
An important aspect to remember is, if you are in cold climates and require heating as a result. The inefficient byproduct of lights is actually useful. So no matter what light you get, you are getting 100% energy efficiency from your light source as both the light and heat are being utilized. In this case, light efficiency is of no concern where by whatever heat is reduced from lowered efficiency, has to be replaced with electrical heating.

This of course is invalid when there is too much heat.
