Aquarium LED Light Bars

LED light bars sit neatly across the top of your tank and are one of the most popular ways to light a planted aquarium or aquascape. Ours are RGB models, which let you adjust the colours to bring out your plants, make your fish stand out and set the mood of the tank. They are designed for aquascaping, giving plants the brightness they need while showing the layout off at its best.

Our light bars have adjustable mounting legs, so a single unit can fit a range of tank lengths, and the aluminium housing helps carry heat away from the LEDs. Check the length range on each listing to make sure you choose the right bar for your tank.

Measure the length of your tank before you buy and choose a bar whose range covers it, so the legs sit securely on the rim. If you want to keep brightness under control, our lighting range also includes controllers and dimmers, which you can find in our main Lighting & Accessories collection. If you’re not sure which bar suits your tank, pop in or give us a call and we’ll help you choose.
