First of all, starting from the production of LED light sources, the color temperature of the light source cannot be fixed, and the color temperature value has a range. For example, this 4000K color temperature wall washer will be controlled at 4000-4500K from the beginning of the production of the light source. In the meantime, you can negotiate with the packaging manufacturer to reduce the interval to make the color temperature more accurate, but it cannot be fixed.

In addition, in the production of products, the color temperature deviation will be caused due to the process. Of course, the manufacturer will control the extent of the color temperature deviation as much as possible to make the light source close to the original color temperature.

LED wall washer manufacturer Yueyao has a few tips for you:

(1) Inquiry through industrial and commercial registration: There are many online platforms for inquiring about company information. You can inquire whether the manufacturer is a legally registered entity by obtaining business licenses, product certificates, certification materials, etc. from the manufacturer.

(2) Inquiry through network information: By searching the company name, click to view some information registration and word-of-mouth information about the company on various platforms.

(3) Inquiry through the company's official website: If we want to know as much as possible about a company, we can use the company's official website to learn about daily news and so on.

(4) Inquiry by phone: In addition to understanding the strength of the factory, you can call a friend of the lighting engineering project or a friend near the factory to find out how the factory's reputation is.

Before the wall washer manufacturer accepts the customer's order, the process of customizing the color of the lamp body is generally as follows:

1. Color board confirmation: The customer needs to provide some of the colored stones on the wall as the color board required by the wall washer. The wall washer manufacturer will embed and spray the lamp shell according to the color board provided by the customer.

2. Confirmation of the color of the lamp shell: After the wall washer shell is sprayed with a similar color according to the color plate, the customer needs to confirm whether the color difference between the color of the shell and the color plate is acceptable. If it is not acceptable, a second spraying confirmation will be carried out. Why is there a second confirmation? In fact, the color plate and spray treatment may not be 100% similar. The similarity is generally between 80% and 90%. The customer's acceptance of the color difference is different, so the first confirmation is very important.

3. Mass production: After the customer confirms the first piece of the wall washer shell color, the wall washer manufacturer can arrange mass orders.
