How many inches of downlights and spotlights should be used in home improvement?

Downlight and spotlight are confused by many people. I don't know what's the difference between these two lamps, where they should be used at home, and what's the difference in application effect. Simply put, downlight is a kind of lamp that focuses more light than ordinary surface mount lamp, and is generally used for general lighting or auxiliary lighting. A spotlight is a highly concentrated lamp, and its light irradiation can specify a specific target. It is mainly used for special lighting, such as emphasizing a place with great taste or originality. Let's talk about the difference between downlights and spotlights from five aspects:

Difference between downlight and spotlight: 1, ceiling opening

General household downlights have three opening sizes: 2 ",2.5" and 3 ". The larger the opening size, the higher the overall height of the downlight, and the greater the requirements for the depth of your ceiling. Generally speaking, the height of downlight after stretching is between 10 cm and 13 cm, so the ceiling depth of downlight is generally above 13 cm. If the ceiling is too shallow, the ceiling installation of ceiling spotlights only needs 6 to 8 cm.

The difference between downlight and spotlight: 2. light source

From the light source, downlights can be equipped with incandescent bulbs and energy-saving lamps. Yellow when incandescent lamps are installed. When installing energy-saving lamps, the type of bulbs can be white or yellow. Because the number of downlights at home is generally large, considering the energy saving problem, energy-saving lamps are generally installed in downlights. Now there are miniature energy-saving lamps specially made for downlights on the market. The shape of energy-saving lamps can be divided into two types: 2U tube and spiral tube, and the wattage types are 3W, 5W, 7W and 9W. In addition, the downlight is fixed and its light source direction cannot be adjusted, while the light source direction of spotlight can be changed.

The difference between downlight and spotlight: 3. Light efficiency requirements.

The downlight uses energy-saving lamps inside, with white light and yellow light to choose from. Diffuse light source does not concentrate light and its temperature is low. Therefore, it is mainly used for lighting, and the angle of light source cannot be adjusted. Generally used in aisles, bedrooms and living rooms. The spotlights used in home decoration are divided into embedded spotlights and exposed spotlights, which are generally used in living rooms, bedrooms, TV background walls, wine cabinets, shoe cabinets and so on.

The difference between downlight and spotlight: 4. price

From the price point of view, spotlights are more expensive in the same class. Generally speaking, the domestic brands of downlight spotlights with better quality are Opal, Sanxiong Aurora, NVC, Ye Song and Li San. Among them, Ye Song's NVC and Sanxiong Aurora have the best cost performance. There are generally three types of downlights: large (5 inches), medium (4 inches) and small (2.5 inches). At present, the market price is between 25- 15 yuan, 28-32 yuan, and 36-48 yuan. Of course, the above prices do not include light sources. There are two types of downlights: horizontal plug and vertical plug, and the price of horizontal plug is a little more expensive than vertical plug (even if it is the same material).

The difference between downlight and spotlight: 5. danger

Generally speaking, downlights are safer than spotlights. Generally speaking, you can't use spotlights to illuminate woolen fabrics at close range, and you can't have flammable obstacles at close range, otherwise it will easily cause fires. Downlight won't have much consideration in this respect.

The above is the difference between finishing downlights and shooting lights. I believe you have a certain understanding of the difference between the two now, so remember not to place flammable items where the spotlights shine.
