Description
The 400 W Bajaj HPSV Lamp is a high-performance high pressure sodium vapour discharge lamp specially developed for powerful illumination in large outdoor and industrial spaces where broad coverage, strong beam penetration, and dependable night visibility are essential. Bajaj’s HPSV lamp range is widely used in conventional HID lighting systems paired with matching 400W choke and ignitor assemblies for stable operation under continuous long-hour service.
This lamp operates using sodium vapour discharge arc tube technology that produces an intense golden-yellow light known for excellent fog penetration and long-distance visibility. Compared to standard low wattage lamps, the 400 watt HPSV lamp generates extremely high lumen output ranging approximately between 45,000 to 56,000 lumens, making it highly suitable for high mast poles, road lighting, industrial yards, warehouse exteriors, railway platforms, stadium peripheral zones, construction projects, and perimeter security installations.
Manufactured with robust tubular outer glass construction and E40 heavy-duty cap fitting, the lamp ensures secure placement inside compatible flood light or street light luminaires. It requires a 400W electromagnetic ballast/choke and ignitor for proper current regulation and reliable lamp starting. Once ignited, the lamp offers consistent warm sodium illumination with relatively lower operating cost for large area lighting compared to many traditional mercury systems.
Because HPSV technology is widely preferred in industrial utility lighting for its broad throw and dependable all-night performance, this lamp remains a trusted solution in municipalities, factories, warehouses, highways, petrol depots, loading yards, and utility service compounds. The average life of up to 18,000 hours further reduces replacement frequency and maintenance downtime in elevated installations.
Supplied by VKA Electricals Private Limited, the 400 W Bajaj HPSV Lamp is an economical and powerful outdoor discharge lighting option for contractors, industrial buyers, electrical departments, and infrastructure projects requiring reliable heavy illumination.
