RANG DONG LIGHT SOURCE AND VACUUM FLASK JOINT STOCK COMPANY (Business ID & Tax Code: 0101526991) is one of Vietnam’s oldest and most recognizable names in the lighting and household appliance industry. With over 2,300 employees and headquarters at 87–89 Ha Dinh Street in Hanoi, this publicly listed joint stock company — known by its ticker RAL on the HSX exchange — has built a strong brand across generations. From electric light bulbs to vacuum flasks and modern LED systems, Rang Dong products are a fixture in Vietnamese homes.

According to the latest Company Report and Private Financial Data analyzed by VBI, the company posted USD 343.31 million in revenue and USD 24.29 million in profit in 2024 — both showing modest growth after a major jump in 2023. Its total assets reached USD 340.23 million, and working capital stood at a healthy USD 116.5 million, indicating strong operational capacity. Owner’s equity rose to USD 135.65 million, continuing a two-year trend of balance sheet strengthening. This consistent performance underscores Rang Dong’s ability to modernize while staying commercially competitive in a shifting market.

Yet the company’s story isn’t just about numbers. In 2019, Rang Dong made national headlines when a fire engulfed its Ha Dinh factory, sending shockwaves through the community and sparking concerns over mercury exposure. The incident led to intense scrutiny and remains a cautionary tale about industrial safety in densely populated areas. Adding to its public challenges, former Chairwoman Le Thi Kim Yen — who remains a significant shareholder — has also faced legal and financial complications, including questions around governance during her leadership.

Despite these challenges, the current leadership, including Chairman Tran Trung Tuong and General Director Nguyen Doan Thang, have worked to restore stability and rebuild public trust. New investments in a modern factory in Bac Ninh Province and improved transparency in shareholder management have helped the company regain its footing.

Rang Dong today is a company at a crossroads — proudly profitable, technically advanced, but shaped by hard lessons in crisis management. For investors, partners, and industry observers, it is a vivid example of how legacy brands in Vietnam are navigating a new era of accountability, growth, and global competition.
