Aqua Illumination AI Replacement Lens

The optical lens on an AI Hydra or Prime isn't just a protective cover — it's the final element in the light path that determines how the LED output is shaped and directed into the water column. A cracked, scratched, or yellowed lens doesn't just look bad; it scatters light, reduces effective PAR at the coral surface, and can create uneven light distribution across the tank footprint that shows up as inconsistent coral coloration or growth patterns that don't match what the Mobius intensity settings would suggest.

Lens degradation is usually gradual: UV exposure yellows the material over years, and the small scratches that accumulate from normal cleaning compound into meaningful optical scatter. If your fixture output seems lower than it used to be and the LED array and power supply check out, inspect the lens closely under direct light for micro-scratching and discoloration before assuming the LEDs themselves have degraded.

These are genuine AI replacement lenses manufactured to the original optical specification for Hydra 32/64 and Prime 16 fixtures. Aftermarket or improvised lens replacements that don't match the original optic geometry will change the fixture's beam spread and PAR curve in ways that may not be obvious until you see the effect on the tank.

Compatibility: AI Hydra 32HD, AI Hydra 64HD, AI Prime 16HD
Replacement indicators: Visible cracks or chips; yellowing or haze visible when held up to light; unexplained PAR reduction on a fixture with known-good LEDs and power supply
Handling: Clean the new lens with a microfiber cloth only before installation — fingerprints on the optical surface will scatter light and reduce effective output.
