The illuminance value of indoor lighting is not as good as 1000 or 750 lux, which can be said to be both good and inappropriate, depending on what your room is used for. As for the color temperature, my personal suggestion is 4000K K, the height of 3 meters is not too high, and ordinary straight fluorescent lamps can also meet the lighting needs. If high illumination is really needed, it is recommended to use floodlights to fill the light. The above remarks are for reference only, please correct me, thank you!
