Prime Flex Arm - 12 Inch

- +

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 the Flex Arm even has that covered, supplying clips that can attach directly to the Flex Arm and secure the power cord for the Prime LED, keeping things neat and clean.

  • Easy Installation
  • Wire management clips
  • Soft coated arm
  • Compatible with Rimmed or Rimless tanks up to 1.20" (30mm)

I’m curious if this is the improved or new style of flex arm by Aquaillumination that uses a mounting block instead of a single mounting screw
Question by: Jarred Anton on Feb 4, 2020, 9:02 AM
Hey there,

They are the newer ones that have the block.

Take care

Hey there,
Thank you for reaching out with your question.
The Prime Flex Arm has a threaded end that is attached to the arm that threads into the light mount lug on the light.
