Making a powerful, blinding LED lamp for large and medium-sized living spaces with your own hands is very simple. All this became possible thanks to the appearance on the radio electronics market of powerful LED matrices with drivers built into them.
Such a matrix is connected directly to a 220 V AC network and only requires cooling.

Making a 100W LED Lamp
We very carefully disassemble the energy-saving lamp without damaging the bulb, disposing of it in an appropriate way.
In addition to the bulb, we also remove the internal driver; we will no longer need it. Of the entire lamp, we only need part of the body with a base.
We disassemble the 9 Volt power supply.
Let's try it on the lamp body. If it doesn’t fit, we nibble the board a little in the corners without damaging the tracks on it.
We take a fan with a built-in cooler, it is designed for 12 V power supply.
Let's try on an LED matrix for it. We drill 4 holes for it in the radiator. Then we cut the thread.
We coat the contact surface with heat-conducting paste and fasten the matrix to the radiator with screws.
Solder the wire sections to the matrix
We solder the wires coming from the fan to the output of the power supply board.
Now we combine everything into a common circuit: we solder the wires from the lamp base first to the power supply board, then we solder the wires from the LED matrix.
We put the board inside the body of the future lamp. And we fix everything with two-component glue.
We put the radiator on top.
Glue it over the entire surface with superglue
After completing all the assembly work, we try to twist the fan impeller with a wire to make sure that nothing will interfere with its rotation.
The 100 W lamp is ready for use.
Screw it on.
It is not recommended to look at it directly, since the 100 W LED power is quite strong, which may not immediately affect your vision.
It shines very, very brightly.
For small rooms this power is overkill.
The camera doesn’t convey this, of course, but the light is blinding.
The 9 Volt unit was not accidentally applied to the 12 Volt cooler. All this is done in order to reduce the noise coming from the fan by reducing the voltage. As a result, it is almost inaudible.
Thanks to the use of active cooling, the lamp itself turned out to be no more than an ordinary one, although its analogues are several times larger in power than its size.
