Orphek OR4 iCon Blue Plus LED Bar vs Orphek OR4 iCon Reef Day LED Bar

Both bars share the same OR4 iCon platform: aluminum body, IP67 sealing, 8mm acrylic cover, Wi-Fi/Bluetooth app control and the same 6W dual-chip LEDs. The difference is spectrum. Blue Plus is a narrow 380–500nm blue/violet bar built for coral fluorescence and actinic supplementation. Reef Day is an 18,000K full-spectrum bar running 390–760nm, so it carries the white light your fish and viewing eye need. Buyers rate both 4.6 out of 5, and owners of the OR4 line generally praise the app and the build; the common complaint is that the app takes time to learn.

• Choose the OR4 iCon Blue Plus if you want a dedicated blue/violet bar to add actinic pop and supplement an existing white fixture.
• Choose the OR4 iCon Reef Day if you need a full-spectrum 18,000K bar that can light the tank on its own.
