Certainly, more lights spaced close together will provide a more even and continuous glow. The SCM series come in a range of sizes of 4,6, and 10 LEDs. Smaller boats from skiffs up to 21ft (6 m), can be covered with one light on either side of the transom. The size of fixtures chosen typically depends on budget and desired brightness. Smaller skiffs are often adequate with one light in the middle. For larger boats using the SCR series, typical installation starts with two lights and one for every additional 5ft (1.5) of beam width over 3 meters.
