Orphek OR4 iCon Blue Plus LED Bar vs AquaIllumination Prime 16HD

Buy the OR4 Blue Plus bar if you want a wide, blue-heavy strip that lights a long tank evenly and can be linked into one Orphek app. Buy the Prime 16HD if you have a small or cube tank and want one compact, fully programmable fixture with a moonlight channel. The Orphek is a long aluminum bar with an IP67 rating; the Prime is a small plastic puck-style light that is not waterproof. Owners rate the Orphek highly for blue color and spread, while Prime users like the app and the compact footprint but note it covers only about 24 by 24 inches.

• Choose the OR4 Blue Plus if you run a long tank and want a wide blue/violet bar that mounts over the length of the reef and can be daisy-chained with other Orphek iCon lights.
• Choose the Prime 16HD if you have a nano or cube tank and want one small, app-controlled fixture with a dedicated moonlight channel.
