LED single tube power 0.03-0.06 watts, using DC drive, single tube drive voltage 1.5-3.5 volts. The current of 15-18 mA reflects the speed and can be operated at high frequency. In the case of the same lighting effect, the power consumption is one ten thousandth of the incandescent lamp, one-half of the fluorescent tube, Japan estimates, if adopted LEDs that are twice as efficient as fluorescent lamps replace half of Japan's incandescent and fluorescent lamps, saving up to 6 billion liters of crude oil per year. The same effect of a fluorescent lamp is more than 40 watts, while the power of each LED is only 18 watts. .
