In connection with a big scam to instill thoughts about the need to install energy-saving lamps at home, many began to install them en masse in their homes. But soon you notice with surprise that the durability of such lamps is a maximum of half a year, the brightness and temperature of the light do not stand up to criticism, and the price, even for non-branded energy-saving lamps, is 10 times higher than for conventional incandescent lamps. Of the fluorescent lamps purchased last year, more than half have already burned out.

If you also have used lamps lying around at home, you can remake them by removing the internal board of the converter and replacing it with a voltage reduction circuit for power supply LEDs. Supply current LEDs We set the resistor to 100-200 Ohm, within 20-50mA.
So, we disassemble the lamp, removing the converter board and the glass bulb (as a rule, it is this that burns out the fastest). What remains is a cartridge with a capacious base. There we will place the assembled circuit with LEDs and a reflector.
LEDs, of course, will not give the same brightness as a fluorescent lamp, but if you buy not consumer goods for $0.1, but branded ones, the brightness of 6 pieces will be at a fairly decent level.
These LED lamps are already being produced in industry, but their price is still higher than that of energy-saving lamps.
