Umm. The or is good , but less power than a B.B.Any reason for this suggestion?
two B.B. will give Bette coverage to avoid shading (and add t5 etc)
A razor is made for long tanks and the diodes are set for that.
Strips will shoot a narrow beam so you lose front and back. Several strips would work , but....
Basically choose a light that fits the shape kinda
