FAQ
- What does “full spectrum” mean for aquarium lights?
Full spectrum means the light delivers a broad range of wavelengths (including white, blue, red, and green) to support both plant photosynthesis and natural-looking fish coloration.
- Do these lights work for planted tanks?
Yes. Several models include dedicated plant-supporting LEDs and adjustable brightness to foster healthy growth and vibrant aquascapes.
- Is a timer essential for reef or freshwater tanks?
For freshwater planted tanks, a timer helps simulate natural day-night cycles and reduces algae risk by providing consistent lighting patterns.
- Can I mix colors to achieve a particular look?
Many models offer RGB or WRGB channels for customizing color balance and mood, which is useful for highlighting fish or plants.
- What should I consider before choosing a 30–36 inch light?
Consider tank length, plant needs, your preferred control complexity, and whether you want extra features like a built-in thermometer or memory on power loss.
- Are higher wattages always better?
Not necessarily. You should match light intensity to your tank depth, plant types, and the coverage area to avoid algae or insufficient growth.
