30cm & 45cm Aquarium LED Lights

Shop 30cm and 45cm aquarium LED lights for nano tanks, 1ft aquariums, 1.5ft tanks, planted aquariums and freshwater displays at Aquaholics Online.

Our compact aquarium lighting range includes RGB, full-spectrum, tropical and planted LED lights designed for smaller aquariums where good coverage, colour and efficient lighting are important.

30cm Aquarium LED Lights for 1ft Tanks

30cm aquarium lights are ideal for many 1ft fish tanks, nano aquariums, shrimp tanks and compact planted setups.

They provide a neat lighting solution for smaller aquariums without the excessive overhang that can occur when using larger light fittings.

When choosing a 30cm aquarium light, check the manufacturer's recommended tank length and adjustable mounting range, as some fittings can accommodate tanks slightly shorter or longer than 30cm.

45cm Aquarium LED Lights for 1.5ft Tanks

45cm aquarium lights are commonly suited to 1.5ft aquariums and other compact freshwater tanks.

They are a popular option for:

• Planted nano aquariums
• Tropical community tanks
• Shrimp aquariums
• Aquascapes
• Small display tanks

Lighting for Small Planted Aquariums

Small planted aquariums still need appropriate lighting to support healthy plant growth.

Low-light plants such as Anubias, Java Fern and many easy-care species can grow successfully under moderate aquarium lighting, while carpeting plants and faster-growing stems may require stronger full-spectrum lighting together with suitable fertilisation and CO2 management.

For a complete planted setup, combine suitable lighting with live aquarium plants, quality planted aquarium substrate and the right plant nutrients.

RGB & Full-Spectrum Aquarium Lights

RGB aquarium lighting uses red, green and blue LEDs to improve colour rendition and create a vibrant aquarium display.

Full-spectrum lighting is designed to provide balanced illumination across the aquarium and is a popular choice for freshwater and planted tanks.

Depending on the model, aquarium LED lights may also include:

• Adjustable brightness
• Multiple colour modes
• Full-spectrum output
• RGB colour enhancement
• Adjustable mounting brackets
• Low-energy LED operation

How to Choose a 30cm or 45cm Aquarium Light

Before choosing a light, consider:

• The actual length of your aquarium
• Tank depth
• Whether you are growing live plants
• The lighting needs of your plants
• The adjustable mounting range of the light
• Brightness and dimming controls
• Colour spectrum

A light should provide even coverage across the aquarium without creating excessive glare or leaving large dark areas.

How Long Should Aquarium Lights Be On?

For many freshwater aquariums, around 6–8 hours of lighting per day is a practical starting point.

Planted aquariums may need adjustment depending on the strength of the light, plant growth, nutrient levels and CO2 availability. Using a timer can help maintain a consistent daily lighting period.
