Aquarium Lights: FAQ

How do I ensure the light fits my tank correctly?

Measure your tank length precisely; most AliExpress lights feature extendable brackets that adjust 10-20cm, but the fixture housing should match your tank size for even coverage. Avoid buying undersized units that leave dark corners.

What specs indicate a light is good for live plants?

Ignore generic wattage and look for 'Full Spectrum' or RGB listings that mention PAR values or specific wavelengths (like 660nm Red). These technical specs ensure photosynthesis capability rather than just brightness.

Is it safe to buy aquarium electronics regarding water damage?

Check the IP rating in the product description; IP67 or IP68 is essential for lights sitting inside a hood or near splashing water. Aluminum housings also dissipate heat better than plastic, preventing moisture buildup damage.

Will fragile LED bars arrive safely during shipping?

Top-rated sellers typically ship long LED bars in rigid PVC tubes or heavy-duty cardboard. Always review recent buyer photos to verify the current packaging standards before purchasing.

Recommendations for buyers

✓
Spectrum Customization
Look for models with built-in timers or Bluetooth app control to simulate sunrise and sunset cycles, which reduces algae growth and stress on fish.
✓
Heat Dissipation Material
Prioritize fixtures made with aluminum alloy shells over plastic. Efficient passive cooling significantly extends the lifespan of high-power LED diodes.
✓
Lens Penetration
For tanks deeper than 45cm, ensure the LEDs have optical lenses (usually 90 or 120 degrees) to punch light down to the substrate for carpet plants.
