Most 1w emitters aren't going to have 20-30 degree beam without reflection cups. The typical natural emission angle for good 1w diodes is minimum 60 degrees.

If you're going to go blue-heavy, ignore 610nm, and 630nm, typical RGB diodes are poorly matched for emissions (they're meant more for display purposes than horticulture,) and UV isn't worth much, you get the same effect just by going heavier on the 460nm light. Far red is only usable in combination with 660-670nm radiation and only when it's far-red in the 720-740nm range to stimulate the Emerson effect for enhanced photosynthesis, but even that isn't necessary as the blue light will help handle that job as well.
