Formerly known as Prakash Tubes, Surya Roshni has two divisions -- the steel division and the lighting division. The steel division, which commenced operations in 1974, manufactures electrical resistance welded (ERW) steel pipes and tubes, and cold-rolled formed sections and profiles, and cold-rolled (CR) strips. The lighting division, operating since 1983, manufactures flourescent tube lamps (FTL), general lighting systems (GLS), glass shells for GLS lamps, tubular glass shells, FTL filaments, GLS filaments, and sodium and mercury vapour lamps. The lamps are sold under the Surya brand. A backward intergration to manufacture lead glass tubings and an expansion of capacities of the lighting division were undertaken in 1993.
The company recently completed a project to manufacture halogen lamps and decorative lamps. Its backward integration project to manufacture ribbon glass shells, FTL tube drawing lines, GLS filaments, FTL filaments, GLS caps and GLS chains, is under implementation, out of which two GLS lamp groups, GLS lamp filament and automatic FTL packing machine were completed in 1995-96. The technologies for the above projects are from GB Glass, UK, and Falma, Switzerland. The projects for GLS lamps, GLS filaments, lamp caps and electrostatic coating were also completed in 1995-96, while those for ribbon glass shells and tube drawing projects, will get over in 1998. All the products except ribbon shells are totally for captive consumption.
Surya Roshni has also set up a joint venture with Osram, under the name Osram Surya Pvt Ltd to manufacture compact flourescent lamps.
