Dimmable LED Aquarium Light with Built-in Timer
This freshwater LED aquarium light combines full-spectrum output, precise dimming, and a reliable day/night controller in one slim, practical fixture. Built for planted tanks and community aquariums, it delivers consistent light levels while keeping heat and moisture firmly under control. Multiple lengths and extendable brackets make it compatible with standard glass thickness from 5 mm to 12 mm.
Key Features
Full-spectrum light for healthy plants and vibrant fish
Balanced output across 400–700 nm supports photosynthesis in aquatic plants while bringing out the natural colors of fish. The spectrum is carefully tuned to avoid excess algae growth, giving you clearer water and healthier growth without constant pruning.
Built-in 24/7 timer and smooth dimmer
The digital controller includes preset sunrise, daylight, sunset, and moonlight phases with gradual ramping. Fish experience less stress thanks to natural light transitions, and you no longer need a separate timer or complicated setup.
Quiet aluminum heat sink
A 6063-T5 extruded aluminum housing dissipates heat passively. No fan means silent operation, and junction temperatures stay safely below 65 °C under normal use-helping the LEDs last longer and maintain stable brightness.
Moisture-resistant construction
IP67-rated sealing plus conformal coating protects the internal circuits from splashes and the high humidity common in open-top tanks. You can run it confidently even in humid or enclosed setups.
High color rendering (CRI > 88)
Natural color reproduction makes plants, substrate, and fish look true to life under the light, so your tank looks its best every day.

Timer and Lighting Control
The controller uses a 32-bit MCU with non-volatile memory. Settings stay stored for up to 72 hours during power outages and resume automatically when power returns-no need to reprogram after a blackout.
Dimming range: 10 % to 100 % on independent color channels
Ramp time: 15 or 30 minutes for natural dawn and dusk simulation
Default mode: Pre-set 24-hour cycle (sunrise 06:00, daylight 08:00–18:00, sunset 18:00–20:00, night 20:00–23:00)
Custom mode: Fully user-defined on/off times and brightness levels

Applications
Planted freshwater aquariums: Delivers 50–120 µmol/m²/s at typical viewing depths-ideal for low- to medium-light plants such as Anubias, Java fern, and Cryptocoryne.
Fish-only community tanks: Clear, vivid illumination that highlights metallic and iridescent colors without harsh glare.
Paludariums and humid setups: Slim profile and moisture-resistant design work well in enclosed, high-humidity environments.
Installation and Compatibility
Extendable 304 stainless-steel legs adjust laterally to fit custom tank widths. The clamps secure firmly to glass up to 12 mm thick or rest securely on rimmed frames. A 1.8 m DC extension cord with waterproof quick-connect coupling links the fixture to the controller for flexible placement.

Laser engraving, custom color boxes, manuals, and barcode cartons
Anodized finishes in black, silver, or other colors (subject to MOQ)
Regional power adapters (US, EU, UK, AU) with local certifications
Standard MOQ is 200 units per model. Custom packaging or specification changes start at 500 units. Samples ship in 3–5 days; bulk production takes 25–30 days after sample approval and deposit.
FAQ
How does the timer keep settings during a power cut?
The controller stores programs in non-volatile EEPROM. Settings and time tracking remain intact for up to 72 hours. When power returns, the light simply resumes its scheduled cycle-no reprogramming needed.
How is heat managed to protect the LEDs?
An aluminum-core PCB is bonded directly to the 6063-T5 extruded channel with high-conductivity thermal paste. Passive cooling keeps chip temperatures low, limiting lumen loss to under 5 % after 10,000 hours of continuous use.
Can this light be used in saltwater or reef tanks?
This model is designed specifically for freshwater aquariums and plants. Saltwater systems usually require a higher blue spectrum ratio and additional anti-corrosion protection.
What customization options are available?
Spectrum layout, housing length, anodized color, laser logo, controller interface, retail packaging, and regional power supplies can all be adjusted under OEM orders.
What are the MOQ and lead times?
Standard products: 200 units per model. Custom OEM versions: 500 units per model. Samples ship within 3–5 days; production lead time is 25–30 days after sample sign-off and deposit.
