I went with the SAM lights because they have a higher light output than the Color Logics (Color Logics are 50W and SAMS are 75W bulbs). This is especially important if you go with any finish darker than a light blue. I have a white (with blue specs) plaster finish and two SAM lights (19x39' pool) and it is just about right. Any less light output and I wouldn' be happy.
