12″ Blue 460nm LED Aquarium Light
The 12″ Blue 460nm LED aquarium strip uses waterproof SMD 5050 LEDs in an aluminum bar chassis. It operates at 12V DC with a power rating around 3.6W per piece, offering IP67 water resistance for reliable use in aquariums and related setups. The unit is designed for easy connection to a DC jack (size 5.5×2.1mm). For extending runs or waterproof connectors, compatible pigtail options are available. This LED bar is suitable for enhancing blue fluorescence in corals and reef displays while remaining compact and energy-efficient.
12″ Blue 440nm Waterproof LED Light
This 12″ LED fixture features 440nm blue light with 18 LEDs in a robust 5050 SMD array. The aluminum rigid bar supports straightforward mounting and secure placement on tanks or shelves. It includes dual waterproof DC jacks at both ends (5.5×2.1mm) for easy interconnection. Powered by a safe 12V DC supply and rated IP67 for water resistance, it is well-suited for plant stands, aquarium lighting, and reef setups that benefit from vivid blue illumination and energy efficiency.
Aquarium Rigid Blue LED Light Strips
This 2-pack of blue LED light strips delivers 30 blue LEDs per strip in a rigid aluminum profile. The system uses low-voltage 12V DC and features IP67 waterproof rating with waterproof DC jacks at each end for convenient connections. A compact form factor ensures compatibility with many brackets and surfaces, while delivering bright blue illumination that enhances reef colors and fluorescence in both saltwater and planted displays.
hygger LED Saltwater Aquarium Light
This 19W reef-friendly fixture mixes 48 royal blue (440-445nm), 24 cool white (7500K), and 24 UV LEDs (395-400nm). The 24/7 mode enables programmed day/night cycles, with an inline controller offering four programmable channels. It ramps up and down gradually for gentle transitions, supports coral growth and fluorescence, and includes a mounting bracket with two metal legs for flexible placement in nano or larger tanks alike.
VIPARSPECTRA 165W LED Aquarium Light
The VIPARSPECTRA V165 reef light is designed for balanced PAR output over a typical 24×24 inch area. It features dimmer and timer controls, allowing independent adjustment of two channels from 0% to 100% and automated on/off, making it suitable for coral and fish tanks. The full-spectrum layout supports diverse reef life, with emphasis on robust blue and white balance to promote growth, color, and vitality while offering programmable convenience for day-night cycles.
Buying Guide
- Light spectrum: For reef aquaria, prioritize blue-heavy spectra (around 440–460 nm) to enhance fluorescence and coral coloration, while including white or broader spectra for overall growth and visibility.
- Waterproof rating: IP67 or higher is ideal for LED strips or bars used near water or within humid enclosures to prevent moisture damage.
- Power and heat: Look for low-voltage, energy-efficient options. Fans are rare in small fixtures; ensure passive cooling or adequate heat dissipation to maximize lifespan.
- Installation and mounting: Consider mounting options (screws, brackets, or clips) and connector compatibility (DC jack sizes) to simplify setup and future expansions.
- Programmability: Timers, dimming, and 24/7 modes help simulate natural light cycles, supporting coral health and algae control over time.
- Safety and compatibility: Ensure the unit is labeled for aquatic environments and compatible with your tank size and stand or canopy, avoiding overheating near sensitive electronics.
- Scalability: For larger tanks, multi-light configurations or longer bars may deliver more even coverage; plan wiring and power supplies accordingly.
- Budget considerations: While premium full-spectrum lights offer extensive features, targeted blue bars can be cost-effective for specific fluorescence enhancement in smaller tanks.
