Am I experiencing light change shock?

So, I was at a dead freight warehouse store and they had a few of these Phuzion Holophane high bay led fixtures for use in arenas, convention centers, and warehouses. They’re even sealed and suitable for use in wet environments like natatoriums.

I did some research and determined they were available in multiple lumen packages with this one being 5000K spectrum and 24,000 lumens each. They’re huge and heavy and built like tanks. I bought two of them for an obscenely low price. ($75 each)

My question is. Am I dumb for trying this? I was running a single 400w metal halide hid lamp in veg room and a single 400w hps hid lamp in flower room but with this I thought I could run both of these in the veg room and put both 400w hid’s in the flowering room.

So far I’m not so sure it’s going to work. It’s 5000K but I fear something is off. There’s a rather wide dispersion of light so I think I’m losing a lot of intensity out the sides. Maybe I need to DIY some pebbled aluminum reflectors? My plants after having been switched off the metal halide to these LED lights are significantly drooping. Although I am just getting over a slight over-application of nitrogen and recently transplanted them...all about the same time as switching out the lighting...so I’m hoping things recover.

Anyone care to give me their thoughts? Even though there are other factors like I noticed a tiny bit of nitrogen leaf clawing that I’ve corrected and transplanting into larger pots I’m afraid it’s the change in lights. This room is COOL and these lights are barely warm to the touch.

Decreased light levels (if that is the case) and cooler temperatures can make overfertilization issues more significant, because the plant is not doing as much, so to speak. Creating some sort of reflector for those lights will help direct more of their output toward the plants. "Boxing in" that grow space will help in that regard, plus it might help get the temperature up a little.

BtW, how cool is "COOL," lol? Lower 70s, or...?
