1. When installing an incandescent lamp, it is yellow light. When installing an energy-saving lamp, the type of light bulb can be white light or yellow light. The direction of the light source of the ceiling downlight cannot be adjusted. The general household spotlights use quartz bulbs, or lamp beads. Of course, large spotlights do not necessarily use quartz bulbs. The quartz bulb only has yellow light. Moreover, the light source direction of general spotlights can be adjusted freely.
2. Downlights are generally installed in the ceiling. Generally, the ceiling needs to be more than 150mm. Of course, downlights are also available. It is a good choice to install downlights in areas without ceiling lights or chandeliers. The light should be softer than spot lights. Spotlights can be generally divided into track type, point hanging type and embedded type. Spotlights generally have transformers, but there are also ones without transformers. Built-in spotlights can be installed in the ceiling. Spotlights are mainly used in places that need to be emphasized or expressed, such as TV walls, hanging pictures, ornaments, etc., can play a rhyme to enhance the effect.
3. Spotlights are more expensive for the same grade. Generally speaking, the domestic brands of downlight spotlights with better quality are Op, Sanli, NVC and Sanxiong Aurora. Among them, NVC and Sanli have the best cost performance. There are three types of downlights: large (5 inch), medium (4 inch) and small (2.5 inch). The current market price of small size is between 20-15 yuan, medium size is 28-32 yuan, large size is between 36-48 yuan. Of course, the above prices do not include light sources. There are two types of downlights: horizontal and vertical, and the price of horizontal insertion is a little more expensive than vertical insertion.
