Optimal G.Z. Co, Ltd

Optimal (G.Z.) Co., Ltd. is a subsidiary of STATELY      Incorporation, which has more than ten years? manufacturing and sales experience of high-tech products in Hong Kong, Taiwan and the Mainland of China. In order to provide better service and higher-quality products to customers, STATELY set up Optimal (G.Z.) in 1995.


In view of energy saving and environmental protection, Optimal (G.Z.) started to put into  R&D and sales of LED lighting in 2008.Based on the original mature photoelectric measurement and control technology, we has developed a series of high-performance LED lighting products according to the light, machinery, electricity and heat characteristics.

Optimal (G.Z.) competitive advantages lie in the selection of upstream from the LED chip, packaging materials and professional processing methods.  Owning  to the understanding of the chip, packaging methods and materials, when design lightings we can choose the right product at the source, are available for the product reliability and lifespan, and do an effective control cost, we can provide complete total solution.

1) OEM/ODM service provided.

2)  Uniform color temperature of light source. In accordance with the International ANS standard, process control in three steps within the tolerance of the color (3SDCM), especially COB products, and currently without COB light auto testing equipment in the industry, Optimal (G.Z.) has developed its unique processing technology to ensure the conforming product color, can adjust the different color temperature according to customers requirements. Thus, we have the advantage on the application of commercial lighting.

3) Control the temperature. The reliability and lifespan of the LED products (color cast, light failure) are influenced by temperature, and LED heat come from LED chip and packaging materials, including the LED chip current saturated, density bear ability, solid crystal glue of the coefficient of thermal conductivity, the selection of encaps
