That is entirely dependent on the plants you have chosen for your aquarium. If you only use “Easy” plants, 10-20 lumen (0.25 to 0.5 watts) per litre is sufficient. Planted Aquarium lighting recommend 20-40 lumens (0.5 to 1 watts) per litre for “Medium” plants, and more than forty lumens (1 watt) per litre for “Advanced” plants.
Aquarium Lighting types:
- Fluorescent lights are designed to convert electrical energy into visible light as effectively as possible. They may provide 50-75 lumens per watt, which is several times more efficient than an incandescent bulb. They can convert 22% of the energy into visible light. They produce less heat because they are more efficient at creating light. Furthermore, they have a lengthy lifespan, lasting 10,000 hours. While fluorescent lights cost more than incandescent bulbs, they are frequently the superior choice.
- LED lights are extremely efficient. LED light bulbs may provide 100-175 lumens per watt, making them the most efficient form of light widely used in aquariums. In contrast to incandescent lights, they used 10% less energy to provide the same quantity of light. LED lights are also far more efficient than fluorescent lights. LEDs produce less heat because they are efficient at converting energy to visible light.
- Incandescent lights are ordinary light bulbs with a wire filament that glows and generates light when heated. They were invented and popularised in the 1800s and are still commonly used today.
There are many possibilities available, so choose what works best for you. The optimum quantity of light is critical and selecting the appropriate type will enhance the atmosphere of your aquarium.
