The difference between downlights and spotlights: 1. The opening sizes of home downlights with ceiling openings are generally 2 inches, 2.5 inches, and 3 inches. The larger the opening size, the greater the overall height of the downlight. The higher it is, the greater the depth requirement for your suspended ceiling. Generally speaking, the height of the downlight after it is fully stretched is between 10 cm and 13 cm, so the depth of the ceiling where the downlight is installed should generally be above 13 cm. If If the suspended ceiling is too shallow, you can consider installing ceiling spotlights or horizontal downlights. The installation requirements for ceiling spotlights are only 6 to 8 centimeters. The difference between downlights and spotlights: 2. Light source. From the light source, downlights can be equipped with incandescent bulbs or energy-saving lamps. When an incandescent lamp is installed, the light is yellow. When installing energy-saving lamps, depending on the type of bulb, it can be white light or yellow light. Because there are generally a large number of downlights in the home, and considering energy saving issues, downlights are generally equipped with energy-saving lamps inside. Now there are mini energy-saving lamps specifically for downlights on the market. The shapes of energy-saving lamps are divided into two types: 2U tubes and spiral tubes. There are four types of wattage: 3 watts, 5 watts, 7 watts, and 9 watts. In addition, downlights are fixed and their light source direction cannot be adjusted, while the light source direction of spotlights can be changed. The difference between downlights and spotlights: 3. Light efficiency requirements: Downlights use energy-saving lamps, with white and yellow colors to choose from. They are diffuse light sources, do not focus, and have low temperatures. They are auxiliary lamps, so Mainly for lighting, the angle of the light source cannot be adjusted. It is generally used in the hallway, around the bedroom and around the living room. Spotlights used in home decoration are divided into two types: recessed spotlights and exposed spotlights. They are generally used in living rooms, bedrooms, TV background walls, wine cabinets, shoe cabinets, etc. The difference between downlights and spotlights: 4. Price. Looking at the same grade in terms of price, spotlights are more expensive. Generally speaking, domestic downlight spotlight brands with better quality include Opple, Sanxiong·Aurora, NVC, Songye, and Sanli. Among them, NVC and Sanxiong·Aurora, Songye has the best value for money. Downlights generally come in three types: large (5 inches), medium (4 inches), and small (2.5 inches). The current market price of small size is between 25-15 yuan, medium size is between 28-32 yuan, and large size is between 36-48 yuan. Of course, the above prices do not include light sources. There are two types of downlights: horizontal ones and vertical ones. Horizontal ones are slightly more expensive than vertical ones (and they have to be made of the same material). The difference between downlights and spotlights: 5. Danger Generally speaking, downlights are safer than spotlights. Generally, spotlights cannot be used to illuminate wool fabrics at close range, nor can there be flammable obstacles at close range, otherwise it will easily cause Fire, downlights will not have too many considerations in this regard. The above is the difference between downlights and spotlights compiled by Self-Study Network for everyone. I believe that everyone now has a certain understanding of the difference between the two. Then remember to pay attention to the place where the spotlight shines and do not place flammable objects.
