Aquaillumination (AI) Prime 18″ Flex Arm
The Aqua Illumination Prime Flex Arm was designed to exclusively work with AI Prime LED lights. The mount is very robust and adaptable, allowing you to use the Flex Arm on any type of aquarium rim up to 1.20″ (30mm). The flexible portion of the arm has a silicone coating, allowing easy cleaning while protecting it from moisture.
The included set screw system allows you to twist the arm within the base, letting you fully secure your Prime LED to the screw attachment point. After your Prime has been snugged to the Flex Arm, you can loosen the set screw located within the base and twist the arm until it is perfectly flat, then tighten the set screw (do not over tighten the set screw, hand tighten only).
One of the biggest issues with mounting lights can be wire management, and this flex arm helps reduce clutter by providing a clean, adjustable fit.

The flex arm fits my 12-inch tank perfectly and stays secure even during water changes. The silicone coating makes cleaning easy and the light stays in place without wobbling. Great for a clean, organized setup.

Works well with my AI Prime LED. The arm adjusts smoothly and the set screw is easy to tighten. I appreciate the flexibility and the fact that it doesn’t interfere with the wiring.

Installed it in under 5 minutes. The silicone coating is durable and doesn’t degrade after a few weeks of use. The arm stays flat and the light is positioned exactly where I want it.
