This full-spectrum LED fixture provides controlled illumination for freshwater planted systems and fish-only aquariums. Equipped with an integrated memory timer, the light automatically resumes scheduled 6-hour, 10-hour, or 12-hour photoperiods following power interruptions. The slim aluminum body dissipates heat passively, eliminating fan noise while maintaining LED diode operational efficiency.
Key Features of LED Aquarium Light with Memory Timer
Power-Off Memory Retention: Internal IC retains timer programming and spectrum configurations during grid outages.
Integrated 3-Mode Timer: Pre-programmed operational windows (6H / 10H / 12H) with automated sunrise/sunset dimming transitions.
Full-Spectrum Spectrum Output: Combination of 6500K white, 460nm blue, 620nm red, and 520nm green LEDs optimized for aquatic plant photosynthesis.
Passive Thermal Management: Extruded 6063 aluminum housing acts as a continuous heat sink without mechanical cooling fans.
Splash-Proof Enclosure: IP67-rated sealed light body protects internal circuitry against humidity, splashing, and accidental water contact.
Extendable Mounting Brackets: Stainless steel side rails adjust to fit multiple aquarium frame widths.

Timer & Lighting Control
The inline controller manages duration, dimming levels, and light channel selection without requiring external smart plugs or app configurations.
Memory Functionality: An internal supercapacitor powers the memory circuit during outages up to 72 hours, eliminating the need to reset daily schedules.
Photoperiod Durations: Selectable operating windows of 6, 10, or 12 hours.
Ramp-Up / Ramp-Down: Automated 15-minute gradual brightness shift simulates natural daylight transitions, reducing sudden stress on livestock.
Intensity Control: 10-level PWM dimming adjustment from 10% to 100% total output.
Applications of LED Aquarium Light with Memory Timer
High-Light Planted Aquariums: Delivers target PAR values for Glossostigma, Eleocharis, and red stem species in setups up to 45 cm depth.
Low-Light Planted Aquariums: Provides uniform light coverage for shade-tolerant species including Anubias, Microsorum, and Cryptocoryne.
Freshwater Community Tanks: Enhances natural pigmentation in cichlids, tetras, and livebearers using balanced red-green-blue spectra.

Installation & Compatibility
Rimless & Rimmed Tanks: Stainless steel bracket legs slide into top slots and lock over glass thicknesses up to 12 mm.
Canopy Integration: Low-profile housing (12 mm height) allows placement underneath enclosed aquarium hoods where space is constrained.
Clearance Requirements: Maintain a minimum distance of 15 mm between the fixture housing and water surface for optimal thermal performance.
Product Construction
Light Body: Anodized 6063 aluminum profile provides corrosion resistance in high-humidity environments.
Lens Cover: High-transmittance acrylic diffusion plate ensures uniform light dispersion and prevents localized spot-glare.
End Caps: Impact-resistant ABS plastic sealed with silicone gaskets to prevent moisture ingress.
Cabling: Heavy-duty DC cable with waterproof screw-lock connectors between the light fixture, controller, and power supply.
Quality Control & Testing
Every production batch undergoes systematic verification to ensure compliance with electrical and operational standards:
Ingress Protection Testing: 30-minute water immersion test at 1-meter depth to verify IP67 seal integrity.
Thermal Stress Test: Continuous 48-hour burn-in testing under full load inside an enclosed 40°C chamber.
Spectroradiometer Verification: Integrating sphere testing verifies CCT, CRI, and PPFD parameters match design specs.
Power Cycle Testing: 1,000 automated power-on/power-off cycles to evaluate timer chip stability and memory retention.
Drop & Vibration: Packaging drop tests compliant with ISTA-1A standards prior to shipment.
OEM & Private Label
Custom Spectrum Configuration: Ratio of white, red, blue, and green LED chips tailored to specific customer spectrum requirements.
Housing Color Finishes: Anodized matte black, silver, or custom color powder coatings for minimum order quantities.
Custom Packaging: Full-color box printing, user manuals, and barcode labeling designed according to buyer brand guidelines.
Laser Marking: Custom logo and model details etched directly onto the aluminum housing or controller casing.
FAQ
Q: How does the memory timer react during an electrical power outage?
A: An internal memory capacitor saves the selected duration and intensity settings. When power restores, the fixture resumes operation in sync with the set photoperiod without requiring manual resetting.
Q: What is the ingress protection rating of this aquarium fixture?
A: The main fixture body achieves an IP67 rating, protecting internal electronics against moisture, heavy condensation, and brief accidental submersion.
Q: Can the light intensity be adjusted for low-light plant setups?
A: Yes. The inline controller features 10-level PWM dimming, allowing illumination adjustment from 10% up to 100% output to match plant species light requirements.
Q: What certifications are available for North American and European markets?
A: The complete product assembly holds CE, RoHS, FCC, and ETL certifications, ensuring compliance with regional electrical safety and environmental standards.
Q: What options are available for OEM branding on the product and packaging?
A: Services include laser-etched logos on the aluminum housing, custom outer box artwork, custom controller casing prints, and modified spectrum diode layouts.
Q: What is the typical LED lifespan and lumen depreciation rate?
A: The LEDs operate with an L70 rating exceeding 30,000 hours, maintaining over 70% of initial light output after three years of continuous daily use under standard operating temperatures.
