Cree LED light for growing question. Need help!

Hey,
I have 4 of these cree LED light fixtures (see images)
Currently the driver for the led light is 347volt. I'm wondering if it is worth It for me to replace the driver to 120volt in order to use these lights in my 4x4 grow tent. It looks like the spectrum is 40k white, Which is what has me in the fence about using these to grow. If not I will continue to use my 600watt digital ballast.
If someone could please give me their input that would be great.
Iv attached the nameplate specs in the pictures aswell.
Thanks a ton!

Hey Thanks!
My main concern is growing with the 4000k spectrum from seed to flower. I know it will work but I don't want to waste power on unusable light for the plant. Fixtures are 135 real watt consumption putting out 20,000 lumens. It's just right I'm the middle of the more used light spectrums

well i can tell ya cree own spec to replace a 1000 watt hps was using 4000k. i myself use 4000 and 3500 for flowering. They work great from seed to bud and at that lumen per watt is pretty good 145 lumen per watt is good.

edit yup thats 411 watts for 4000k at 60000 lumen i would do it for sure

To replace the driver you would need to know the DC output or the circuit design and emitter part numbers. The driver doesn't list DC output and the datasheet doesn't either.

Where are you getting 20,00 lumens from?

That part number indicates it's a 96 watt unit with 12,400 lumens. 129 LPW which is not bad for total system efficiency. It's probably similar to HPS per watt, so it would be like downgrading from 600 to 400 even if you can sleuth out the dc requirements.

Hey Thanks for the advice.
Here is the fixture. Cree cpy 250 and specs. I would purchase the driver from cree as they have 120 volt as well as 347volt options. I also have 4 of these fixtures. These fixtures are dimmable so that's why the values change. I would run then on max, My main Concern is more about the light spectrum being 40k thru full plant life cycle.

Here is the datasheet for CPY250. The B in the part number seems to indicate a 96w variant. 137 total watts on the driver, I'm not sure why it's listed that way. If that's the input then it shares the same part number with a 96 watt unit.

If you can get drivers for them at 96w I would consider running them in the corners with the 600 in a 4x4 tent.

Whether you can put the 120v drivers for the E type in them I'm not sure but in that case it would be a reasonable replacement for a 600w unit but not necessarily better. I think the good upgrade would be to run them at 96 watts each with the HPS.
