The difference between downlights and spotlights
When designers choose lighting fixtures, it is very easy to make mistakes. They use spotlights for general lighting and downlights for crafts and decorative paintings. This leads to confusion in the illumination of the indoor space and wastes energy, resulting in a large contrast. So how should downlights and spotlights be used? Where should downlights be placed? Where should spotlights be placed? Reasonable use of lighting fixtures can better create a sense of lighting atmosphere.
1.The difference between spotlights and downlights
▶Spotlight:
Concentrated light, three-dimensional lighting effects are mostly used for background wall washing to create an atmosphere.
There are 15°, 24°, 36°, 38° and other beam angles to choose from.
Suitable for background walls, artworks, decorative paintings and other spaces that need to be focused on.
▶Downlight:
Diffuse light, large lighting area, mostly used for normal lighting.
The lighting angle is large, such as 24°, 45°, 60°, 120°
Suitable for spaces with high lighting ratios such as entrances, corridors, kitchens, and bathrooms.

2. Spotlight and downlight selection guide
Spotlight and downlight selection guide:
1. Choose the one with the smallest glare value. URG stands for Unified Glare Rating, which is an indicator used to measure the glare level of the lighting system. The lower the value, the smaller the glare level and the better the lighting quality. When choosing an anti-glare diffuser, usually pay attention to the requirement of URG <19 or <16 to ensure the comfort of the lighting environment.
2. Choose a cup body. Black cup body has better anti-glare effect. White cup body can be better integrated with the ceiling.
2. Choose the depth of the cup body. A deep cup has a better anti-glare effect, and you can see the light but not the lamp.
3. Flicker. Choose lights without flicker, which can greatly reduce damage to the eyes.
4. CRI: If you select a high CRI, the color restoration of the object will be high; if you select a low CRI, the color restoration of the object will be low;
5. Choose the light angle, 15°: used for focal lighting, suitable for small decorations or crafts. 24°: used for key lighting, suitable for coffee tables, dining tables, etc. 36°: used for wall washing lighting, highlighting the complete uniformity of the space, suitable for wall washing or hanging paintings. 45/50°: used for basic lighting, suitable for high-brightness space lighting, suitable for bathrooms, kitchens, and corridors.
