Description
This lamp is designed and rated for 240 Volts and runs at 12 milli Ampères and is constructed from an old B22 lampbase of a defective CFL lamp.
The led layout is up to youe own ideas, as long it fits safely in the fitting.
A great addition for at night, or use it as curiosety lamp to add a bit of character in your house or hallway.
As mains voltages are involved here work with precision and make a tidy job of the lamp.
The resistors run hand warm to the touch and should not be rated at a less power rating as shown in the explanation at the beginning of the video.
For 110 or 120 Volts and 25 Led's (3.3V) at 12 mA a resistor value of 3125 ohms is required.
Use 4 x 820 ohms 1 Watt resistors ( standard E 12 series)
This lamp has been in service for 12 hours a day with no faillures or loss of brightness.
