I went with the gen5 pros and 2 purple+ and 2 actinic bulbsFor those going Gen 5 + T5s, IMO it makes more sense to get the pros. Of course you can turn up or down the blues on the blue but most of us cannot switch out LED diodes, T5s allow you to completely change the bulb/look. In other words it makes sense for the light that cannot be changed to be neutral. I'll probably be going G5 Pros with blue plus.
