Wow just saw a big jump in pricing for Solar System series.
I love the product design and controller - but this is priced high anyway. Now it’s way out of the HomeGrow budget.
It’s a hobby not a commercial enterprise. They must be selling to a lot of commercial houses now.
Seems that DIY COB is STILL the best efficient use of my hard earned money.
I agree with you @poppa. California Lightworks are so overpriced. Not worth the money to me! I’m a big Marshydro fan, and I’ve been getting amazing results from their economicly priced lights.
Their SP3000 and FC5000 are game changers!
There is nothing spectacular about their driverless design. They use Osram top BIN leds in their high end lights. Samsung diodes are also top BIN. So are Bridgelux…
I have two SX250’s I am doing a product review on currently. They work well but I have built 200W Bridgelux strips that crush these 200W California Light Works…
This is a Blueberry Autoflower under a SX250
Plant looks great. If you know how to build a cob light setup and driver - then you know how to fish and don’t need to go to the market any longer.
I thought that COB’s were already getting outdated with the quantum boards out now? I have two lights with 4 COB’s in each along with the red spectrum’s in single BIN led’s. They are what I refer to as my kinda blurple lights lol.
My main lights I built are Bridgelux Vero SE COB’s - 90CRI, 3000k and they crush grows 
Yeah, I build PCB and COB. I prefer the Chilled Logic PCB pucks over HLG boards
My COB’s are great as well
What kind of sugars did you feed this thing? Any?
How cool at night does it get?
That is frosty as Jack’s Beanstalk
Advanced Nutrients Bud Candy 
My Winter grows tend to be cooler. Night temps in the upper 60’s. Days can get as high as 80F depending on how many grow zones I am running
So lets say to compare…I bought a Spider Farmer SF 4000 which is listed as being the equal to a 1000w light. What is the light output of the ones you make with the COB’s ?
3000k for the graph
I also run Emerson Effect (Far Red/Photo Red) which is not included in these graphs
Wow I sure didn’t expect a light meter grid lol! So what does it cost you to build one of those? I’ll have to pop over to Amazon and look at the SF 4000 light grid don’t remember anything about the numbers now been about a year since I got it. What distance is that grid at from the sensor?
Im with @poseidon build your lights and learn how to. I built my own also and a lot cheaper.
It depends on where you source parts but I think I paid around $350 or so…
I got the COB’s from Digi-Key. I use RapidLED.com for everything else
Those numbers are at 18”. You can get higher running a little lower but light burn becomes an issue. I don’t run CO2 so no need for higher values
Amen, brother
Im hitting 860 watts. The corners are 5500 k and red + far red. The main boards have 5500k white and red+far red and uv leds. But 8 have 2x 480 watt meamwell drivers and take 10% out for efficiency variances
The Emerson Effect has a significant impact on flower. I am glad to see more growers adopt this in their light recipes Bravo
