UV and IR can be beneficial.
There is a recent fad of adding a lot of 730nm to fixtures, to imitate HID fixtures. This should be good for flowering, in colder environments, because it will increase leaf temperature, but it will likely cause stretching of seedlings.
The UV and IR is fairly minimal with these, keeping a positive R : FR ratio, so it will likely work well for full cycle growth.
