How to make aquarium lighting with LEDs

LED (Light Emitting Diode) lighting is an excellent option for a saltwater or freshwater aquarium. LED lamps do not consume much electricity. Differ in long and rather easy operation. These features allow you to reduce operating costs for a long time. Environmentally friendly LED lighting does not contain harmful chemicals such as mercury or phosphorus, unlike fluorescent lamps. You have the opportunity to install LED lighting aquarium with your own hands, if you use the instructions.

Advantages and disadvantages of LED lighting

  1. LED aquarium lighting is initially expensive, but standard LED lamps currently work up to 50,000 hours, and are cheaper if you count on their long-term perspective.
  2. LED lighting also emits less heat, so it does not always require fans and cooling systems (depending on the number of lamps installed).
  3. Determine what type of LED light will best suit your needs for lighting a fish tank. If you have a salt water aquarium, more powerful LED lights will be required. Large and deep tanks also require strong lighting.

  4. This is ideal for a tank with relatively small plants. Tanks with lively underwater reefs require more light, and buying LED aquarium lamps with higher power ratings is highly recommended.
  5. Electricity and water in the interaction form a charge that can be deadly. The human body works as a channel between them, and with improper maintenance of the lamps, injury from electric shock may occur. Turn off all electronics, wiring systems and lighting when installing LED lamps, and drain the water from the aquarium. It will protect your life.

Look at the LED backlit aquarium.

How to install LED aquarium lighting by yourself

The first method, how to make LED lighting aquarium do it yourself is the simplest. Here you can use the cover with a special backlight. It is recommended to attach white LED stripes around the perimeter of the lid, which will provide a variety of spectrum and ensure uniform illumination of the upper perimeter of the tank.

The second method is to make a small "chandelier". Above the tank it is necessary to make a block of square, round or diamond shape, in which you can put all the equipment and LED strip. Lighting capacity of 120 watts is enough for a spacious tank with a capacity of 250-300 liters, where many fish and plants live. Such a "chandelier" may contain about 40 LED lamps with a luminous flux of 270 lm (lumen), 3 watts each. The brightness of the illumination will be more than 10,000 lm, which will provide a bright light spectrum in an aquarium of such a volume. The main thing is to constantly monitor the balance of the ecosystem: an excess of green light contributes to the growth of microbes.


How much does it cost to assemble such a lamp? The cost may be different, depending on the seller. It is advisable to buy LED lamps from trusted manufacturers, so that they last for a long time and do not create installation difficulties. Reliable imported LED lamps: Osram, Cree, Philips, Lumileds. Russian manufacturers of LED dump: "Feron", "Camelion", "Jazzway", "Gauss", "Navigator", "Era".

To mount the lighting with such bulbs yourself, you need:

  • Buy a lot of LED bulbs, LED strip;
  • Plastic trench 10 cm wide and 2 meters long;
  • Power supply 12 V, can be carried out from a stationary computer;
  • Take the soft wire 1.5 mm;
  • Get air conditioning at 6-12 V;
  • No LED connectors are needed for the LED strip; 40 lamps are required for the lamps;
  • Cutter for holes 48 mm.

After all materials have been prepared, two grooves should be cut along the plastic construction, and about 20 pieces should be drilled in the lower part. at 1 meter, you can staggered. Then in the holes you need to put the LEDs, and fix them. All lamps must be connected to the power supply. If you do not know how to properly handle the wiring, contact an electrician who can perform the procedure correctly.

The cooler or fan should be placed in the place of evaporation or heating of the lighting coating. For decorative purposes, you can make a night light, which will become an imitation of moonlight. It is needed for tropical sea fish and sea anemones. For night light, you can use a blue LED ribbon, which can be installed on the back wall. An electric lighting timer or automatic switching on / off of the backlight must also be connected in order to regulate the amount of daylight required.


The lighting of the aquarium should come from its upper part - this is how soft and diffused light is formed. It is better to use an ICE lamp with a power of 1 W, however, for different aquariums the appropriate power is chosen. A LED strip of 30-40 light bulbs with a total power of 3 watts may be enough for a 200-liter tank. The main thing that the light was not too bright, and not harm the slaves and plants. The optimal calculation is 0.5 watts per 1 liter of water, but for a deep and spacious aquarium in the formula, all indicators must be multiplied by two.

It is also important to take into account the thickness of the bottom - visually the water and all bottom plants should receive enough light in the lower layers of the tank. Bottom fishes and snails require a little light, but the plants will still grow and require more light. In the process of photosynthesis, plants will require a lot of light, because of its deficiency will emit less oxygen. To avoid problems, you need to adjust the amount of daylight, and create a uniform lighting in the pond, which will receive every inhabitant.

LED lamp for aquarium do it yourself

Making a LED lamp for an aquarium for a craftsman is not at all difficult. The main thing - stock up on all the necessary components and tools.

What do you need to make an LED lamp for an aquarium?

  • aluminum radiators ("skis") 107x420 mm for the installation of LEDs on them, at the same time they act as a lamp body;
  • star LEDs, which are calculated depending on the volume of the aquarium. For example, for an aquarium of 120–200 liters, you will need about 30–40 LEDs across 3B of different shades of white; you can add several night blue LEDs for a beautiful night illumination of the aquarium;
  • adjustable drivers;
  • 2 aluminum corners 50x20 for the frame, corner 12x12;
  • screws, drills, sealant and other consumables;
  • the glass is 920x107 mm in size, because we need a waterproof LED aquarium light in close proximity to water.

Getting Started

So, the first step in creating an LED lamp for an aquarium with your own hands will be the preparation of the corners: cutting out the "ears" on them at the edges for which the lamp will hold in the aquarium cover.

At the ends of the radiators, ream the holes with a thread for mounting, fasten the LEDs with wires and do the first fitting on the aquarium.

Insert the glass and install the end plates. To the lamp lying on the cover of the aquarium, attach two corners along the lamp. If desired, you can pour sealant along the glass.

Lighting and on-time adjustment is made using variable resistors and mechanical timers. To cool the lamp, fans are constantly running at minimum speed. It is better to hide all drivers and regulators in the cabinet under the aquarium, leading the wires from them to the lamp.

This is what a DIY lamp for a marine aquarium looks like.
