when choosing lamps, we need to consider the following four issues: lamps with perfect optical performance, for example, using floodlights to illuminate the wall, can cast beautiful light spots, but they cannot be calculated beforehand, and lamps without perfect optical performance cannot be calculated. In addition, the illumination data alone cannot determine the perfection of the lighting effect, and it is also necessary to confirm whether the light emitted after turning on the light is beautiful, rather than making a decision based on the optical data alone.

1. Don't make the lighting too conspicuous. The space is not a place for lighting exhibition. You should choose the form of lighting as simple as possible.

2. Choose lamps that will not produce glare.

3. Choose efficient lamps. Especially in large space places such as offices, the design lighting is relatively high, and there are more lamps of the same type. The efficiency of lamps has a great influence on the utilization of operating costs.
