18 watt lamp for plants


Good day to all. Today I will tell you how to make an 18 watt LED bulb for plants out of ordinary unnecessary parts.

We take the base from the light bulb, the radiator can be from the processor. My from a powerful transistor.

9 LEDs 3 watts red 4 pieces and blue 5 pieces. Panels for soldering LEDs 3 pieces and a power supply for three-watt LEDs in my case, it is 20 watts.


We fasten the holder for the radiator to the base E 27.

All diodes must be connected in series, for this we cut the negative track on the boards.

We solder the power supply to the base, and the output to the plus and minus terminals of the board.


Our 18 watt lamp is ready. Screw in the cartridge and check.

The temperature of the radiator after three hours of operation did not exceed 30 degrees.
