    How a flashlight could reach 24000Lm?

    I saw many introduction on 3-5W led flashlight, declare their ones could reach 24000LM, according to current led light efficiency 120-150LM, which at least 160Watts, so how it can be ? If it is lighting intensity 24000Lux, i believe, but luminous flux... very worry about the introduction.
