Hello everybody. Today I will tell you how to make lighting for aquarium fish.
To do this, we need a piece of Plexiglas 10 cm by 15 cm thick 1-2 cm, 12 LEDs with a diameter of 8 mm and a power of 0.5 watts.
In plexiglass, we drill 12 holes of 8.5 mm from above.
We insert the LEDs there and fix them with silicone.
I connected the voltage of the 3.7V LEDs 4 in series and I got three groups since I have a 15V power supply. But you can connect everything in parallel or everything in series - it all depends on the power source.
For the float, I took a piece of plastic pipe with a diameter of 50 mm, sawed a hole there in the thickness of Plexiglas and inserted Plexiglas there and filled everything inside with foam, when the foam dried, I cut off the excess and connected the power.
The floating lamp is ready, it is completely safe for the aquarium. I took a warm glow of LEDs, but you can replace them with green or colored, it all depends on which fish you live.
