Thought I would repost this as my plants have been getting ample 630 from 1 UVL Aquasun + 2 ZooMed florosuns + 3 UVL Red Lifes. Additionally I have 1/8 UVL 660 + 1 Coral Wave:
This is from an led discussion, but the spectral needs are the same no matter the lighting choice:
Couple that with strong white light (green-response chlorophyll extending throughout and deep into leaf structures, with a net effect at or near that of the (mostly) surface-level blue and reds), which also takes care of most of the ~660nm+ you actually need for photomorphogenesis - and you can get by with 630nm reds just fine.
(i.e. 630nm red is ~95% of the PSR of 660nm, AND they currently still have ~20-30% greater radiometric efficiency - as well as being cheaper than the deep reds - so there's more 'bang for the buck'):
Apparently true for T5s too. The 660 MSRP being ~ 1/3 more expensive than the Red Life
