Engineering lamps: in a broad sense, customized lamps are engineering lamps. Professionally, lamps beyond the type of home lighting are basically engineering lamps. Engineering lamps have no restrictions on size and materials.

"Non standard" means "not manufactured according to the specification".

General products have their own manufacturing specifications in order to be common with other products (for the convenience of use and repair). For example, the "screw" we often use is a standard part. You can buy screws of the same specification in any shop.

"Norms" include national norms, local norms, professional norms and other forms, which complement each other.

"Non-standard" products or spare parts refer to products that are less used or spare parts specially manufactured for a certain product, so it is not easy to buy general or substitutes.

Sometimes, "non-standard" parts are intended to do so in order to protect the uniqueness of their own production and repair.
