The Dimmable LED Aquarium Light with Built-in Timer is an engineered freshwater LED fixture that combines full-spectrum output, precision dimming, and an integrated day/night controller. Designed for planted tanks and freshwater aquariums, this unit maintains stable photosynthetic active radiation (PAR) output while minimizing heat accumulation and moisture ingress. Available in multiple length configurations with extendable mounting brackets, it fits standard glass thickness from 5 mm to 12 mm.
Key Features of Dimmable LED Aquarium Light with Timer
Full-Spectrum Spectrum Tuning: Balanced output across 400nm–700nm wavelengths promotes plant photosynthesis and enhances natural fish coloration without encouraging nuisance algae.
Integrated 24/7 Timer & Dimmer: Built-in digital controller supports preset sunrise, daylight, sunset, and moonlight cycles with gradual ramping to reduce fish stress.
Aluminum Alloy Heat Sink: 6063-T5 extruded aluminum housing provides passive thermal management, eliminating cooling fans and maintaining junction temperatures below 65°C.
Moisture-Resistant Sealing: IP67-rated conformal coating on PCB assemblies prevents circuit corrosion caused by water splashing and evaporation.
High Color Rendering (CRI > 88): Delivers natural color representation for aquatic plants, substrate, and freshwater species.

Timer & Lighting Control
The integrated control unit uses a 32-bit MCU with internal memory retention, preserving program settings during power outages up to 72 hours without battery backup.
Control Specifications & Functions
Dimming Range: 10% to 100% brightness adjustment across independent color channels.
Ramp Up / Down Duration: Gradual light transition over 15 or 30 minutes to emulate natural dawn and dusk cycles.
Time Modes:
• Default Mode: Pre-programmed 24-hour cycle (Sunrise: 06:00, Daylight: 08:00–18:00, Sunset: 18:00–20:00, Night: 20:00–23:00).
• Custom Mode: User-definable ON/OFF schedules with custom brightness levels.
Applications of Dimmable LED Aquarium Light with Timer
Freshwater Planted Aquariums: Delivers necessary PAR levels (50–120 µmol/m²/s at 40 cm depth) for low-to-medium light aquatic plants such as Anubias, Ferns, and Cryptocoryne.
Fish-Only Freshwater Tanks: Provides vivid illumination for tropical freshwater species, highlighting metallic and iridescent scale pigments.
Paludariums & Terrariums: Slim line chassis allows mounting within humid enclosed setups.

FAQ
Q: How does the internal timer retain settings during power interruptions?
A: The controller utilizes non-volatile EEPROM memory. When main AC power disconnects, settings and time tracking remain stored for up to 72 hours. Upon power restoration, the fixture automatically resumes the scheduled lighting cycle.
Q: What thermal management measures prevent premature LED decay?
A: The fixture uses an aluminum-core PCB mounted directly to a 6063-T5 extruded aluminum channel using thermal silicone paste with 1.5 W/m·K conductivity. Passive convection cooling maintains chip temperature below critical thresholds, limiting lumen depreciation to under 5% over 10,000 continuous hours.
Q: Is this fixture suitable for saltwater or reef environments?
A: This model is engineered specifically for freshwater aquariums and freshwater aquatic plants. Saltwater applications require different spectral ratios (higher blue spectrum intensity) and upgraded anti-corrosion housing coatings.
Q: What customization options are available under OEM orders?
A: OEM services include custom spectrum layouts, housing lengths, anodized surface colors, laser-etched brand logos, custom UI/button configuration on controllers, customized retail packaging, and regional power supply compliance.
Q: What is the standard minimum order quantity (MOQ) and lead time for bulk orders?
A: Standard product MOQ is 200 units per size model. Customized OEM packaging and spec adjustments carry a standard MOQ of 500 units per model. Sample orders ship within 3–5 days; bulk production lead time is 25–30 days upon sample sign-off and deposit receipt.
Q: How is the IP67 waterproof rating achieved and tested on the production line?
A: Waterproof sealing combines ultrasonic-welded end caps, silicone perimeter gaskets, and conformal potting resin over internal circuitry. Random samples from each production run undergo high-humidity chamber exposure and pressurized water spray testing.
