Buying Guide: Key Considerations For 36–Inch Tanks
- Light spectrum: For planted tanks, look for full-spectrum LEDs (roughly 6500K white with blue and red components). Some models add green, pink, or purple LEDs to enhance color rendering.
- Brightness and PAR: A higher LED count typically yields stronger light. Check PAR ratings at various depths if you have dense foreground plants or tall aquatic species.
- Coverage and mounting: Ensure the fixture length overlaps the tank length with extendable brackets so the light sits evenly across the entire surface.
- Timer and memory features: Auto-on/off schedules, sunrise/sunset simulations, and memory after power outages reduce manual adjustments.
- Power efficiency and heat: LED solutions save energy and typically run cooler than older fluorescent fixtures, which benefits long-term use and fish health.
- Durability and splash resistance: IP ratings (like IP68) provide protection in splash-prone areas; verify installation guidelines for your setup.
- Ease of control: Some lights offer app control or remote dimming; others rely on built-in timers. Choose based on your preference for automation.
- Plant compatibility: If you maintain a planted tank, verify the fixture supports the plant species and growth stage you target, particularly high-light species.
- Maintenance: Consider how easy it is to replace LEDs or access the driver if needed, and whether the fixture comes with a warranty.
