Best T5 HO 48” 54W Actinic lamps?

[calebjk]

i am looking to change my actinic bulbs out. I was wondering what everyone's opinions are on the best bulbs out there for the money.
Also, wondering what the benefits/detriments would be if i went with 1 standard blue 460nm bulb and 1 purple 420nm bulb, opposed to just using the normal 2 460nm bulbs.

The 420nm super/pure actinics are lower par bulbs than the 460 nm blue bulbs. If you want to run a pure actinic with a blue, UVL makes the best and highest par 420nm actinic and the ATI Blue Plus is the highest par very blue looking bulb (460nm look with best par).

That;'s what I run with my halides now, 2 ATI Blue Plus and 2 UVL super actinic. The Super actinics however don;t have near the par as the blues. They are the Highest par T% pure actinic however so the best choice if you want a 420nm.
