The New AI Prime 16HD shares the same cluster as the Hydra 32HD and Hydra 64HD. The Prime 16HD incorporates 16 LEDs (+1 Moonlight) and an all new TIR optic. What’s New: More LEDs More PAR More Spread Improved Optic Design Improved Water Resistance Thinner Form Factor Dedicated Moonlight Channel Wider Spectrum (more channels) Prime Time: Fully programmable including channel control, intensity and timing from your smartphone. (myAI) BLE onboard – no additional hardware required for programmable control. Onboard button control for basic adjustment. Utilize all current Prime Mounting Hardware including – Prime Mount, Prime Flex Arm 12”, Prime Flex Arm 18” and the Prime hanging Kit. Add them to your myAI profile and create a schedule to coordinate with other AI fixtures. Design: Redesigning the plastics in the Prime and Hydra lineup has resulted in two major benefits: better efficiency and better aesthetics. Efficiency improvements reduce the demands on active cooling for longer component life. Improvements to design thin the fixtures and reduce their profile and presence over your aquarium. Resilient: Water resistance is a major benefit in aquarium lighting – and while the new Primes are not waterproof, design improvements make them more capable of facing the moisture rich adventures of reef keeping. Control: Control on the lights will use the existing myAI app which is free, simple and very quick to program offering onsite direct BLE connection through your smart device. Additional control options may become available for the new generation Prime and Hydras over time.
