Starting in 1983, the Chor Rungsang Lighting Company Limited (CRS) has been at the forefront of the Thai manufacturing and distribution business. Founder Kwanchai Lertsirikhachon debuted with a disco-tech lighting line, followed by flamboyant and industrial fixtures. Next the business incorporated fluorescent fixtures and products into a full range for industrial plants, residences and offices. During this first era, CRS managed to gain the trust of a Japanese construction contractor.  

CRS is currently a designer and manufacturer of outdoor and indoor fixtures and fittings with their state-of-the-art software and machines achieving international standard. Our specialized luminaire creations prioritize quality of light and spectacular design. Imported items such as aluminium light reflectors, spotlights, street lights and LEDs are also part of our offer. Additionally CRS consults customers about personal product optimization. Brand new affiliate “Hilight” is a lighting manufacturer and importer offering experience in using the highest competency lights. It recently unveiled its latest innovation entitled “Smart Lighting” that addresses a wide range of requirements by designers and new generation of customers.      

CRS and Hilight are determined to keep improving the quality of products and service while streamlining management to ensure on-time delivery, safety and highest customer satisfaction.

Research and Development
Because of the transition from fluorescents to LEDs, the R&D Department came into effect in 2015 to analyze information and develop high-in-demand LED products. We prioritize the quality of products, better light competence and energy saving in order to accomplish cost-effectiveness for the customer. The resulting innovations include 6 models of homegrown LED Highbay that feature cost effectiveness, light quality and all-purpose functionality, fulfilling demands in countless areas.


Our path and our next steps

Established by Mr.Kwanchai Lertsirikhachon, CRS operated out of a one-story commercial building. Our first product was disco-tech lightings.

The first important change occurred as when our office was moved to a new business quarter in the Ladprao area of Bangkok. We debuted a host of fixture models such as pendants, chandeliers, as well as industrial and fluorescent fixtures.

Our fixture plant was inaugurated in the Theparak area of the Bang Phli district, Samut Prakan province.

This year mark a milestone in our lighting business as CRS moved to a brandnew 4,800 sq.m factory and became a one-stop-service lighting fixtures manufacturer.

The CNC (Computer Numerical Control) automatic operation was introduced as part of our manufacturing process.

CRS started a new chapter by launching HILIGHT, a model-styled fixture line that focuses on new generation buyers.

CRS, under the name of HILIGHT, aims to push the limits of innovation and technology in the LED, electricity and fixtures business with the ultimate goal to provide top quality light for all users.
