Building cob setups with two clu058-1825 3500k, hlg-240h-c2100 driver,80 degree lens,sst x 100w sinks. 105w each led. Does this sound like a good unit or will I have any bad surprises. May get a little warm running all the way up. Also why are these leds so rarely seen here,to new?

Well I Can Only Guess Its The Cost Of The CLU-58-1825 Which Is 38.00. Now If I Were Building A 200 Watt 2 Cob Setup I Would Go With The Vero29 Gen7 68.1 Volt And A HLG 185-1400. That Set Up Should Get Ya Around 100 Watts Each. My .02 :peace:

Now To Answer Your Other Question. Yes If Your Sold On Citizens This Is An Awesome Setup. The Only Downside Of this Lamp Is It Will Run Hotter Than My Beloved Vero29 Angels :hump:

68V veros arent any more efficient than 1825s at a given wattage.theyre about the same. 1825 goes higher though to 325W if thats what youre into.. i think the 68V vero tops out around 240W

the ssts should be fine at 100W, you lose a little efficiency running hotter but the citis are rated to 140 Tj and you'll prob be at 85-100C tops which is what they design these chips for (run hard, high temps, enclosed luminaire).

above 100W the 2-3W it takes to actively cool a heatsink becomes attractive as you make that back in lumens when you drop the chip temp. at lower wattages its a wash on efficiency vs the energy required to run the fan. when youre running a 3618 over 300W that 3W fan is nothing, but 3W out of 75W is a lot

theyre not new at all, theyve been around forever and were some of the first cobs. the diy scene was dominated by cree as that was a popular brand when it took off a year or two ago, the 5th gen citis eclipsed them in performance/value (6th gen coming in a few mos) but there are lots of chips out there. in a given size cobs from different manufacturers seem to vary more by cost than by performance, they'll all get the job done at the end of the day.

I'm new to DIY LEDs but I am going to jump in and get started very soon. I have over 20 600 watt HIDs and I'm sick of the heat and cooling costs to run them. So... excuse my noobness but how many of the Vero29 Gen7 68.1 volt can a HLG 185-1400 power supply run? I'm crunching numbers now and trying to get an item list together. Thank you!

To Answer Your Question 2. In Your Situation I Would Run A 4 Cob Set Up On A 44 Inch Bar Spaced 12 On Center. That Would be 420 Watts.1 Bar Would Out Produce Your 600. You Could Reduce The Amount Of Bars Need By Running A Light Rail. Also I Would Use The SST-X From Northern Grow Lights. https://northerngrowlights.com/ :hump:

I thought these would be 220w for setup. But doesn't the 240 driver put out 240w

The T1-2100 uses a Cree CXB3590 CD/Top Bin 3500k/80CRI emitter with a Meanwell LPF-90D-42 (2150mA). ~850PPFD in 18x18 @ 14-16".

The T1-V196 usea a Seventh Generation Vero29C 3500k/90CRI using a Meanwell LPF-90D-54 (1670mA). 932PPFD in 18x18 @ 14-16".

If I am putting out 240w with the hlg-240-2100 driver powering 2 leds,120w each will my sst-x passive sinks cool them sufficient?

For The 68.1 Volt Vero29 You Will Need To Run The HLG-240-1400. That Should Produce Between 120-130 Watts Per Cob :weed:

@CobKits Already have the clu058-1825, hlg-240h-c2100,and sst-x sinks just asking if the sst-x can handle the 120 watts passive as running two leds per driver or will I have to dim a bit?
