Three heads with 3W, or a combination of 3+3+5W (that is, 3W in each of the 3 heads and 1W in the middle)

Chandelier purchase and installation precautions

a: The lamp cover material is glass, PC, and light cloth cover. Try not to choose ceramic, resin, metal cages. Mainly the transmittance is higher.

b: Try not to choose a lot of crystal pendants below, simply point, because crystal pendants will make the light reflect and refract on the top, one will be more dazzling, and the other is easy to form the light and shadow of the barge on the wall and ceiling.

C: Only choose the appearance, do not choose the main material, many copper chandeliers, all stainless steel, expensive and expensive, a few thousand lights, are all eggs, first chandelier you do not have to worry about his bad, as long as transportation and It is not bad when it is installed. It will not touch the whole time in the whole life. The indoor environment is not a high temperature and high humidity environment, and there is basically no chance of being bad. The whole copper has a safety hazard. Because he is too heavy, the chandelier is fixed on the ceiling by two expansion screws, and the light weight of the light is safe.

D: If you can buy online, don't go to the store. First, you can choose more appearances for online shopping. It is easier to choose the appearance you like. The most important thing is the price. The difference is basically 70% or even 50%. And now the online shopping service is also very good, when the transportation or installation is a bad cover, take a picture and send it, basically give free reissue. As for some friends who are worried about the installation of chandeliers for online shopping, first of all, you can choose the seller to install the door. Many online shopping offers, and how much to collect. Or find an electrician yourself, and fix a chandelier around 50.

E: When you buy a chandelier, you need to pay attention to the bulb. Different chandeliers are equipped with different bulbs.

Chandelier bulb selection

Classification of light bulbs

The bulbs used at home are mainly chandeliers. According to different installation methods, I divide the chandelier bulbs into two types: formal and inverted. 1: The chandelier is divided into a formal light source and a flip-chip light source, as shown below.

Dressing chandelier

Look at these two chandeliers, see the difference? In the front one, the light bulb is installed downwards, and the rear one is installed upwards, which are called dressing and flipping. Why pay attention to this? Because the LED bulb is not full-angle, we divide the bulb into ordinary bulbs (bulbs), and inverted bulbs (or high-angle bulbs).

The difference between different bulbs

This is a schematic diagram of the light bulb of an ordinary light bulb. He is only suitable for use on a formal chandelier. That is to say, the light bulb is installed, and the light cover is facing the ground. Otherwise, the light will run all the way to the ceiling. The ground and the wall are basically gone. The phenomenon.

If the chandelier you choose is a flip-chip light source, I would recommend that you don't buy LED bulbs and use energy-saving lamps directly, but now I can recommend the following to you. This is to solve the problem of flip-chip light source. One of the products, his characteristic is that the light is illuminated backwards, which is specially used on the inverted chandelier. (There are several patents for this light bulb, please be careful with your peers)

Actual illumination of the upper two ordinary bulbs and the inverted bulb

The front is an ordinary light bulb, and this is a flip-chip bulb (the company's patented product, peer weight)

It can be seen that if the chandelier bulb is flip-chip mounted (that is, the bulb is mounted upwards), the ground is almost devoid of light due to the structure of the LED bulb. Looking at the front ordinary bulb, there is no light on the base of the lamp holder. If the inverted chandelier uses an ordinary LED bulb, the ground has a ten-like effect, basically no light.

The latter patented inverted light bulb, the board is very bright, 90% of the light is reversed, used on the flip chandelier, the ground will be very bright, to achieve the desired lighting effect, while the front also has 10% of the light, to ensure The ceiling will not be dark.

Lamp purchase precautions

A: Please ask the seller to provide an electric light source test report (see that the index should be at least 80 or more)

Please provide the light biosafety test report (mainly to see the blue light is not exceeded)

Please provide the LM80 certification (mainly to see if the light source is good)

The shell is preferred to be a full metal shell. The second choice of plastic aluminum is not used for all plastics.

Note the lamp head, commonly used threaded heads are E14 and E27

Don't buy the wrong one, buy the wrong one, don't go in, pay attention to the length and diameter of the bulb, it is smaller than the size of the chandelier cover, such as the 15 cm cover, you buy a 16 cm long light bulb, there is a leak, it is difficult to see.
