This means that the lamp consumes 250 watts of power when operated at 230 volts. It indicates the electricity consumption and the voltage rating required for the lamp to operate efficiently.
The "T" in a T5 fluorescent lamp stands for "tubular," indicating the shape of the lamp. T5 lamps are thin and tubular in shape, measuring 5/8 of an inch in diameter.
In standard electrical wiring, the black wire is typically the "hot" wire carrying the current, while the white wire is the neutral wire returning the current. If the wire has clear insulation, it may be difficult to distinguish between the two visually. It is best to use a voltage tester to determine which wire is hot.
The cord is attached under the shade and runs outside the lamp along the back
