The Hygger Eyeball Aluminum Alloy Reef Light is a compact yet powerful 36W LED lighting system designed to replicate the beauty of ocean light within a reef aquarium. With a balanced full-spectrum output, three adjustable color modes, and accurate PAR distribution, it supports coral growth, enhances fish coloration, and recreates the natural brilliance of reef environments. Ideal for nano reef aquariums between 16–20 inches. Its aluminum alloy housing ensures superior heat dissipation and durability, while the 360° flexible gooseneck offers effortless positioning for the perfect illumination angle. It delivers professional-grade lighting performance in a sleek, quiet, and easy-to-use design.

Features:
Even PAR & High Output Lighting:

• The HG171 Eyeball Reef Light produces evenly distributed illumination with a carefully optimized LED spectrum. The result is consistent PAR (photosynthetically active radiation) at multiple depths (PAR 431 at 7 in, PAR 182 at 12 in, PAR 137 at 16 in, PAR 93 at 19 in) This steady light intensity ensures balanced energy for coral photosynthesis and vibrant reef coloration throughout the tank.

Balanced Reef Spectrum Composition:

• This precise color mix mimics the light found in shallow reefs, helping your corals and fish thrive in a natural, healthy environment. With 30 high-efficiency LEDs, the reef light delivers a professional full spectrum:
• 3 white LEDs (6700K) for clarity and daylight simulation.
• 12 blue (453 nm) and 10 royal blue (465 nm) for coral fluorescence and zooxanthellae activity.
• 2 violet (415 nm) and 2 UV (395 nm) for enhanced pigmentation and growth.
• 1 red (660 nm) to highlight natural fish tones and balance the spectrum.

Three Light Modes for Custom Ambience:

• Blue Mode: Promotes coral fluorescence and highlights natural glowing pigments.
• Blue + White Mode: Combines depth and brightness, ideal for everyday viewing and coral feeding periods.
• Full Spectrum White Mode: Replicates natural sunlight for daily illumination and overall tank health.

External Controller with Timer and Brightness Adjustment:

• The smart external controller allows effortless customization:
• Light Modes: Switch between Full Spectrum, Blue, and Light Blue.
• Brightness Levels: Adjust to 10%, 32%, 55%, 77%, or 100%.
• Timer Settings: Choose automatic operation for 3H, 9H, or 12H.
• Simple Control: One-touch power and intuitive keys make it easy to set and forget.This user-friendly system supports both coral photoperiod needs and your daily convenience.

Superior Heat Dissipation and Noiseless Operation:

• Utilizes upgraded ball bearing fans, which outperform traditional oil-containing fans in both performance and lifespan.
• The ball bearing fans operate on rolling friction, resulting in a low friction coefficient, high speed, and thus better heat dissipation.
• Generates significantly lower noise levels and has a long service life, estimated at 60,000 to 100,000 hours.

Advanced Cooling System:

• The Eyeball Reef Light features an upgraded ball-bearing fan paired with an all-aluminum multi-fin cooling system. This dual-layer cooling structure maintains stable operation during extended lighting hours. The high-rotation fan provides exceptional airflow with minimal friction, extending LED life while maintaining whisper-quiet noise levels.

Premium Materials and Thoughtful Design:

• The light head diameter is a compact, 3.58 in design that saves space while providing broad light coverage up to 24″x24″
• Gooseneck flexibility has a 360° adjustable arm (13.4 in height) for precise positioning.
• The special anti-rust, flexible, full-aluminum oxidation bracket is suitable for coral tanks of various sizes.
• Operates below 35 dB, making it virtually silent in home or office settings.
• The oblate base effectively increases the contact area, providing stable support and protection for the coral reef tank. It is compatible with tank glass thicknesses ranging from 0.2 to 1.0 inches.
