Ok, built a custom canopy for 3ea 250W MH lamps. Canopy is 5' long with 1ea 4' T5 rigs on each side. These two bulbs are for standalone coral fluorescence display....if it were you what 2 bulbs would you go with...

I researched this in the past and it seems the proteins found in corals fluoresce from the 420nm to 450nm range: actnic to royal blue.
