The right LED light is what turns a tank of struggling plants into a lush aquascape. Aquatic plants need the correct spectrum and enough intensity to photosynthesise, but too much light without matching nutrients and CO2 invites algae. We compared full-spectrum planted-tank LEDs on spectrum, brightness, coverage and useful extras like timers and adjustable channels.

Before You Buy
Key Buying Factors
01
Spectrum
Plants need a full spectrum with strong red and blue to photosynthesise. Lights marketed for plants or full-spectrum growth beat plain white lights meant only for viewing.
02
Intensity and plant demand
Match intensity to your plants. Low-light plants like anubias and java fern thrive under modest light, while carpeting plants need high output plus CO2.
03
Coverage
The light must spread across the whole footprint, not just the centre. Wider tanks need a longer fixture or higher mounting to avoid shaded corners.
04
Timer and channels
A built-in timer or 24/7 mode keeps a consistent photoperiod, and adjustable channels let you dial back intensity if algae appears.
05
Algae balance
More light is not always better. Excess light without matching nutrients and CO2 is the fastest route to algae, so start lower and increase slowly.
06
Mounting
Clip-on and adjustable-bracket lights suit rimless and standard tanks. Check the fixture fits your glass thickness and tank width before buying.
Frequently asked questions
How many hours should a planted aquarium light be on?
Most planted tanks do well with a photoperiod of six to eight hours a day. Start at the lower end and increase gradually, since a long, bright photoperiod without enough nutrients and CO2 encourages algae.
Do I need a special light to grow aquarium plants?
Yes, plants need a full-spectrum light with enough intensity to photosynthesise. A basic light sold just for viewing the fish usually lacks the right spectrum and brightness for healthy plant growth.
Will a stronger light cause algae?
It can, if the light outpaces the nutrients and CO2 your plants can use. Balance is the key, so match light intensity and photoperiod to your plants and dose ferts and CO2 to suit.
