About Rạng Đông
From a light bulb factory founded in 1961 to an industrial-scale LED workshop since 2014.
Rang Dong’s full name is Rang Dong Light Source and Vacuum Flask Joint Stock Company, trading as RALACO. Construction of the factory began in 1958 and it was officially founded in 1961. On 28 April 2000, the company received the title Hero of Labour in the Doi Moi (Renovation) period; in 2004, it became a joint stock company.
In 2007, factory No. 2 in Que Vo Industrial Park, Bac Ninh, began operating; in 2008, the company commissioned a lead-free glass furnace. The lighting R&D Centre was founded in 2011, and the LED – Electronics & Lighting Equipment Workshop in 2014 to produce LED lighting at industrial scale. The company’s systems are certified to ISO 9001:2015, ISO 14001:2015, ISO 50001:2011 and hold VILAS 126 accreditation.
