Flex Arm 12 in. vs 18 in. — Which one to choose?

The Flex Arm 12 in. is ideal for nano aquariums and medium-sized aquariums where the light needs to be positioned close to the water's surface. The Flex Arm 18 in. offers more height and reach for deeper aquariums or sumps where the Prime Fuge needs to be mounted higher. Both models are compatible with the same AI Prime lights.

⚠️ Installation Precaution

Do not adjust the flexible arm while it is mounted on the aquarium rim. Excessive force during adjustments can stress the glass or acrylic.
