4. Turn on the energy saving lamps and rotate the special detection gyro respectively. Special detection gyro pattern, color, will produce the following changes.
A: If the special detection gyro only produces multi-channel black-and-white halo, and the black-and-white halo changes with the rotation speed of the gyro, its rotation direction, rotation speed and color change, and it is stable and fixed, which is similar to the effect under the sun light, indicating that this energy-saving lamp has no stroboscopic and stroboscopic effects.
B: If the special detection gyro produces multi-channel rings with different colors, and each ring will show random changes of rotation direction, rotation speed and color with the change of gyro rotation speed, only the color is lighter. It shows that this energy -saving lamp still produces stroboscopic and stroboscopic effects.
