Before You Buy
Key Buying Factors
01
Light Spectrum
We recommend full spectrum lights with red and blue wavelengths for plant photosynthesis. Our team found that lights with 6500K-7000K white LEDs plus specific red (660nm) and blue (450nm) promote healthy growth.
02
PAR Output
PAR (Photosynthetically Active Radiation) measures usable light for plants. We suggest low light (10-20 PAR) for low-tech tanks, medium (20-50) for most plants, and high (50+) for demanding species with CO2.
03
Size and Coverage
Match light length to tank dimensions. Our team found that lights with adjustable brackets or multiple sizes ensure even coverage. A light too short leaves dark corners, while too long causes algae.
04
Control Features
We prefer lights with timers or 24/7 modes for consistent photoperiods. Bluetooth or app control adds convenience for simulating sunrise/sunset, which reduces fish stress.
05
Heat Output
LEDs run cooler than fluorescent, but some still generate heat. We recommend lights with aluminum heat sinks or fans to prevent overheating, especially in closed hoods.
06
Durability and Warranty
Look for IP water resistance ratings and sturdy construction. Our team found that lights with silicone seals and aluminum bodies last longer. A 1-3 year warranty indicates manufacturer confidence.
Living With It
Care, Cost and Maintenance
Daily Operation
Set a consistent photoperiod of 8-10 hours per day. Use a timer or automated mode to avoid fluctuations. Observe plant and algae response; adjust duration if algae appears.
Cleaning and Maintenance
Wipe the light surface weekly with a damp cloth to remove dust and mineral deposits. Ensure vents or fans are unobstructed. Replace LEDs only if they fail; most last 3-5 years.
Troubleshooting Algae
If algae increases, reduce photoperiod to 6-8 hours or lower intensity. Ensure nutrients and CO2 are balanced. Clean the light and check for hotspots.
Pro tip
Our team recommends using a PAR meter to verify light levels at the substrate, especially for high-tech tanks, to ensure optimal growth without algae.
Frequently asked questions
How many hours should I run my planted aquarium light?
We recommend 8-10 hours per day for most planted tanks. Start with 8 hours and increase gradually. Use a timer for consistency.
Can I use any LED light for planted plants?
Not all LEDs are suitable. Look for lights with full spectrum and sufficient PAR. Standard aquarium lights may not have the right wavelengths for plant growth.
Do I need CO2 with a high-light fixture?
High light without CO2 can lead to algae. We suggest using CO2 injection or liquid carbon if you choose a high-output light to balance plant growth.
How do I clean aquarium light lenses?
Unplug the light and wipe with a soft, damp cloth. Avoid abrasive cleaners. For mineral deposits, use a vinegar-water solution (1:10) and rinse.
What is PAR and why is it important?
PAR measures the light available for photosynthesis. It is more accurate than wattage for plant growth. Aim for 20-50 PAR for most plants, measured at substrate level.
