How to make the lights for the aquarium do it yourself


DIY Aquarium Lighting

Experienced owners know that extra light is needed for beautiful fish coloring and healthy plant growth. It helps to recreate habitual conditions for inhabitants. In addition, proper lighting will help maintain the internal balance of the aquatic environment. And this affects the development and reproduction of the inhabitants of the aquarium.

In a specialized pet store, you can purchase a cover of the desired size along with the aquarium. It already has a built-in lighting system. However, it is not suitable for every aquarium.

Types of lighting for the aquarium?

Incandescent lamps

The most budget lighting option. Most often used in small pools and ponds for fish.

The advantage of such lamps is the required color spectrum - up to 3000 K. It is the most favorable for the process of photosynthesis and algae growth.

There is also a big minus - this is a very low efficiency (only 5%). A lot of energy goes into heat.

Therefore, incandescent lamps are most often used for aquariums with cold-blooded inhabitants (frogs, turtles, newts and others).

Fluorescent lamps

There are two types: specialized and fluorescent lamps. The first type is best suited for lighting containers with plants. They emit red and blue color spectrum, which accelerates the growth and development of algae.

Specialized lamps have their drawbacks: high price and short lifetime (up to a year).

The fluorescent lamp is cheaper and lasts about 2 years. At the same time there is a significant drawback - the growth of algae and the process of photosynthesis slow down.

Halogen bulbs

The brightest light source for aquarium. Their power ranges from 70 to 1000 watts. It has a point orientation and illuminates a specific area.

Light penetrates into the depths, reflecting from the walls and creating a contrast of colors and play with deep shadows. Such lamps are most popular among fans of the aquatic environment.

However, there is a minus in such a light source: it requires cooling for at least an hour a day, because it can burn out due to overheating.

LED strip

They are the most economical light source. In addition, there are ribbons of different colors and shades, and therefore the color spectrum can be recreated independently by combining blue, yellow, white and red. Also, using the switch, tapes of the required color are turned on. But the main advantage is water resistance.

There is a variety of LED strips that are coated with silicone. Without any fear they can be lowered into the water.

Installation of LED strips is very simple - just stick them to the inside of the cover and connect to the power supply. However, it will require a transformer, because the tapes consume only 12V.

How to install lighting for the aquarium yourself?

First of all, you need a frame or a finished cover. The frame itself is best made of wood or OSB-plates. You can take plastic and plexiglass, but it is undesirable, because these materials are easily deformed when heated (depending on the type of lamp being installed, heat transfer can be quite large). The cover can be made by hand.

Inside the lid is pasted with a light-reflecting foil - so all the light will be directed at the aquarium itself. For fluorescent and halogen lamps, special mounts are used, with the help of which they are fastened tightly to the inner surface of the cover. You will only have to connect the wires and isolate the open areas with special tape.

What is a UV sterilizer for underwater inhabitants?

LED strip is much easier to install. They connect to a 12V power supply. Then the protective cover on the back side is torn off, and the LEDs are glued to the cover.

We should not forget that a lot of moisture evaporates from the aquarium. It settles on the lid and can lead to burnout of the LEDs. Therefore, you need to choose a waterproof tape.

After installation is completed, it is necessary to glue the junction of the wires of the LEDs and the stabilizer with silicone sealant.


Backlight in the aquarium is very important for the healthy growth of fish and plants. She is involved in regulating the balance of the aquatic environment. It is easiest to buy a ready-made cover with lighting, but it will be more expensive and not a fact that it will fit every aquarium. Indeed, depending on the size of the aquarium, the types of its inhabitants (fish, toads, tritons or turtles) and plants need different intensity and color spectrum of the backlight.

LED lights for aquarium do it yourself

Modern aquarium lighting from LEDs - economical, does not heat the water and makes it possible to create beautiful color effects. LED backlight from the finished tape for the aquarium is easy to assemble with your own hands, without having special knowledge of physics. It is waterproof, diodes exist in different colors that are easy to combine. There are single ribbons with white color or color - RGB, which can be switched to different shades. Consider how to do your own hands beautiful LED lighting aquarium.

Setting the backlight

To make the lights of the aquarium out of the LED strip with your own hands, you will need to make a frame or use the finished cover of the aquarium. Additionally, you need to purchase:

  • LEDs 12 W - two tapes white and one color;
  • two strips of glass 7 cm each; two 2 cm each and two small pieces;
  • foil adhesive tape;
  • silicone glue;
  • controller and power supply.
