Product Overview Give your marine filtration a smarter, cleaner boost with the UNS Mini Refugium Light. Designed for saltwater setups, this low-profile LED is built to kickstart photosynthesis in macroalgae tucked into rear AIO chambers or under‑cabinet sumps. Ditch brittle plastic brackets; the heavy‑duty magnetic backing lets the light sit neatly over your filtration, saving space and delivering focused, usable PAR exactly where your algae bed needs it. Compatibility Note This model is engineered specifically for UNS Dual AIO Aquariums and UNS Reef System sump lids. If you are running a non-UNS aquarium or a traditional glass sump, a separate clip-on model is available to accommodate your setup! Please inspect your existing sump lid to ensure a seamless installation: Newer Model Sump Lids (With Pre-Drilled Holes): Installation is completely plug-and-play! You will only need mounting clips to lock the fixture securely into position. Older Model Sump Lids (No Pre-Drilled Holes): You will need a standard drill bit set and mounting clips to quickly modify your lid for a perfect fit. Key Features & Benefits Targeted Macroalgae Spectrum: Combines 6000K white, deep reds (620nm & 660nm), violet (420nm), and blue (470nm) to maximize photosynthetic efficiency in Chaetomorpha and Caulerpa for superior nitrate and phosphate export. 8 Color Modes & 10 Dimming Levels: Gives you total control over spectrum composition and PAR intensity to match your system's specific biological load. Smart Inline Timer with Memory: Easily automates reverse photoperiod cycles while built-in memory preserves your custom spectrum and timing settings during power outages. Sleek Compact Unibody: Ultra-thin profile (0.51" thick) slips into cramped, restricted desktop AIO rear chambers and under-cabinet sumps where traditional gooseneck lights won't fit. Heavy-Duty Magnetic Mounting: Provides a clean, tool-free magnetic attachment without brittle clips or bulky brackets cluttering your filtration area. Technical Specifications Please check your filtration compartment dimensions and lid type before installation.

Why is a specialized refugium light important for macroalgae? Macroalgae like Chaetomorpha and Caulerpa require specific red, white, and actinic blue/violet wavelengths to fuel photosynthesis. The UNS Mini Refugium Light concentrates these target PAR spectrums into a compact 10W array to accelerate algae growth, rapidly consuming excess nitrates and phosphates from your saltwater system. 2. What is a reverse photoperiod, and how does the built-in timer help? Running your refugium light at night while your primary display light is off prevents nighttime pH drops caused by respiration. The integrated inline timer allows you to automate this reverse photoperiod effortlessly without external plug timers. 3. Can I use this magnetized light on non-UNS aquariums? This magnetized version is designed to fit UNS Dual AIO rear chambers and UNS Reef System sump lids. For rimless glass tanks, acrylic sumps, or non-UNS setups without integrated magnetic mounting slots, we recommend choosing the UNS Mini Refugium Light - Clip-On model.
