LED T5 combo help

[Teknik777]

Current fixtures:

72 dimmable LEDs. 48 Royal Blue XREs, and 24 XPG

XREs have 80 degree optics, the XPG don't have any optics

2 54T5s, Front bulb is ATI purple plus, back is ATI blue

Any other suggestions for a SPS dom tank on the T5 bulb choice?

I would just use the simple 420nm Actinic with the ATI Purple Plus

What difference or par would the 420 Nm bring that the ATI blue plus isnt?

There would be quite a loss of PAR with a true actinic, but I think with all your LED's, you would be okay. But, if you want, the Geissmen Actinic plus bulb has a PAR level just under the ATI Blue plus, maybe 12-15 less.
