2022-04-08 570

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.

Engineering lamps refer to customized lighting products suitable for specific lighting and playing a decorative role according to the intention and actual needs of the project. They are also called non-standard lamps, decorative lamps, customized lamps, etc. It usually includes customized lamps such as hotel engineering lamps, non-standard lamps, club lamps, KTV lamps, villa lamps, model room lamps, lobby lamps, field lamps and so on.

"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.

Difference between engineering lamp and non-standard engineering lamp

The quality of engineering lamps is ordinary, the materials are not very good, and the price is dominant. Non engineering lamps are oriented to the public. We should take the quality as the advantage, otherwise we can't open the mall, and the price is slightly higher than that of engineering lamps.
