Might be too much depending on the stage of growth.
60.000 lux at canopy, give you ROUGHLY 800 ppfd with these cobs (on average) if that is hitting at canopy level. Those are numbers for peak flowering. Are your drivers B version? if so you can DIM those and slowly increase power week by week as they grow. until you reach max.
or if you can't dim, you could always set the height of the panel higher to compensate.
In my opinion you don't need anything above those numbers unless you are supercharging with CO2.

As seen in this semi-famous thread: A perfect cure every time
IMO required reading for new growers (and probably some experienced ones as well)

The 80 Cri Is On The Right With The 90 On The Left. As You Can See The 90 Cri Once Again Is Starting To Leave The 80 Cri In Da Dust
Also Some May Notice On The Last couple Of Run's That I've Been Running My Ppm In The Mid To Upper 800's . Well That's Due To Using 5ml's Of SLF-100 With Every Feeding. The Dude At The Hydro Store Say's That the SLF-100 Allows you to Run A Higher Ppm Safer Well After Initially Using SLF My Ppms Rose by 150 Which Is Not Bad Considering I Started Using It In The 3rd Week Of Flower. Now Fast Forwards To Today I'm Not Mixing My Solution Any Different Still Measures Out To 1050 Ppm However The Plant Maintains About A Mid to High 800 Ppms.I Believe that By Running The SLF-100 That it Unlocked And Allows The Plant To Uptake More Nutes

I'm just curious what ppfd you're running at atm, and if you've measured how much power each side consumes
I've been wondering all along if the 90cri side gets an unfair advantage by setting both sides using par. Since the 90 cri outputs more photons in a nm range that the meter can't read, if you set both sides to the same ppfd, I would assume that the 90 cri side would be turned up a bit higher (consuming more power and delivering more photons to the plant, even though it has the same ppfd as the 80cri side). Would it make sense to set each side using a killawatt meter instead?
Keep up the great work

Don't Know Ppfd I Set My Lights Up At 35 Inches From The Top. I Then Hook Each Light Up To A Kilowatt Meter And I Set Both Lamps Up A 125 Watts A Piece . I Can Take Measurements Tonight At Lights On To See Where I'm At. I Usually Don't Check Intensity Until 3rd Week Of Flower.Looking good

So the 90cri side has 7% less par. It will be interesting to watch the 2 sides progress.
