Is it necessary to have all aluminum downlights?

It is necessary that all aluminum downlights have good heat dissipation effect, higher durability, and are suitable for large watt-hour downlights, but the price of all aluminum downlights is more expensive. If it is a general decoration, you can also choose PC material downlights, affordable, not easy to conduct heat, good transparency, after adding PC flame retardant, flame retardant and efficient, suitable for small watt-hours downlights. When decorating, you can still choose according to the actual situation of your home decoration.

Downlight material

1, the average family downlight is no more than 2.5 inches, put 5W energy-saving lamps on the line.

2, LED downlights are modern, can be used as a substitute for ordinary downlights, the light is better than ordinary, the only disadvantage is that if the 1 or 2 light points can not be replaced.

3, downlight cover materials are also divided into many kinds, iron, pure aluminum, die casting and other materials, generally speaking, iron downlights are cheap, pure aluminum and die casting and other materials are more expensive, but more durable. The engineering is more used for the iron face of the downlight, but it is recommended that the home decoration of the downlight with a surface cover that is not easy to rust.

Downlight lamp head is a more important link, the main material of the lamp head is ceramic. The reed inside is the most important, there are two kinds of copper and aluminum, a good brand is made of aluminum, and a spring is installed under the contact point, which can strengthen the contact. The other is the power cord of the lamp holder, the good brand is the use of three-wire wiring lamp holder (three-wire that is fire wire, zero wire, ground wire), some will bring terminal, this is also a very basic method to distinguish a good brand and an ordinary brand.

Reflective cups are generally sand cups and light cups, the material is aluminum, aluminum will not change color, and the reflectivity is better. Some small manufacturers will use plastic spray to do, this process looks good, but over time it will become dark, even black. The identification method is to look at the smoothness of the cutting, the cutting of aluminum is very neat, and the spray is the opposite.

Downlight characteristics

1, compact and high luminous flux. The power consumption of energy-saving lamps is 1/5 of that of incandescent lamps, but the life is 6 times that of incandescent lamps, and the compact design of 175 dimensions is maintained, which inhibits the presence of lamps and creates a bright space.

2, there are two kinds of mirror and frosted reflection plate. A shimmering mirror-like reflector that blends the ceiling's frosted reflector with a moderate amount of light.

3, the use of sliding fixed card, convenient construction. It can be installed on the ceiling of different thickness from 3mm to 25mm, and it can be easily removed during maintenance.

4, there are many color temperatures of energy-saving lamps, commonly used 6400K(white light), 4000K(neutral light), 2700K(yellow light) of three types, these three color temperatures can create a different atmosphere. The most suitable color tube can be selected according to different uses.
