Aquarium LED Lighting

Introduction: Aquarium LED Lighting

Who has aquarium knows the importance of lighting for plant growth and for the beauty of the environment.

There are several options from many different prices. For a basic aquarium lighting, LED technology can help. The idea is to be as simple as possible, at lower cost and provide adequate lighting to the aquatic environment. It is used as a basic rule the proportion of 1W per liter of water for proper lighting.

Step 1: Theory

My aquarium has 120 liters, 100 liters useful. Using the rule, it is expected 100W light for the correct illumination. When searching the Internet, I found led strips, single color (pure white) or RGB, allowing customize the color best suited for your environment. Are sold in rolls of 5m with 300 leds of the model 5050, and with power of 72W. Although 72W is less than 100W, I decided to assemble the solution and the result was excellent for my purposes

Step 2: The Solution:

  • 5 meters of Led strip RGB 5050
  • 5A 12V power supply
  • 1 RGB Controller

They are sold in kits:

  • 1.5 mts Aluminum profile like picture above.
  • 1 Double-sided tape
  • 50cm - 4 way ribbon wire
  • Tools such as soldering iron, pliers, wire ...

Step 3: Assembly

I used 1.5m of aluminum profile like a picture above, cut in half and stuck, forming a profile of 75cm with twice the width.

I cut the LED strip into several pieces of 75cm to the same extent of aluminum, and pasted inside.Thereafter the weld has been made between the multiple pieces of tapes using the ribbon wire.

Step 4: Finishing

Once you make the connection, use a black sticker on the other side of the aluminum profile for a better finish.

Step 5: Test It !

After that, turn on the tape with the 12V supply and select the desired color.

Ready light for aquarium simply and inexpensively.

    isn't that theory for fluorescent lamp? LED consume less than half of it, you may need only 45-50 watts LED. Anyway your plants is not in a big number :)

    I made my 30 watts LED for 50 liters aquarium. 60% of the aquarium space are occupied by plants.

    addition: my LED strips is similar with yours, also using flat bracket as heatsink + reflector. anyway, is your double tape heavy duty? I am afraid it will fail holding the LED someday :)

    I used silicone glue instead of double tape... the same glue used by aquarium glass

    Hi Mohammade in theory, yes, but I have not found any reference using LEDs, so ... This lighting is only aesthetic, I think for your plants continue to grow, you'll need a fluorecents lamps with specific length of light waves.

    I replaced the original double tape for the best results, and works well, but your idea to use silicone can be more safely, because some water can damage the strip. You can use waterproof led strip too.
