Buying Guide
When selecting a planted-tank light, consider tank size, plant types, and the desired growth pace. Full-spectrum LEDs with high CRI help plants photosynthesize efficiently while rendering natural colors in fish. A programmable schedule or 24/7 cycle is valuable for maintaining steady growth and reducing algae surges. Mounting options vary from clip-ons to extendable arms; choose fixtures with sturdy brackets and heat-dissipation designs to prevent overheating in longer fixtures.
Key considerations include color temperature preference (most planted tanks favor 6500K white with RGB to push color and growth), dimmable brightness, memory while power is interrupted, and the presence of pre-set or DIY modes that let you tailor sunrise, daylight, sunset, and moonlight. Energy efficiency and long-term reliability matter for year-round operation, especially in larger systems. Finally, verify compatibility with your tank length, glass thickness, and whether the light can cover the entire substrate evenly to avoid shadowed zones.
