CROMPTON SONTHO400 TUBULAR HIGH OUTPUT

The Crompton SONTHO400 Tubular High Output is a 400W high-pressure sodium (SON) lamp built for powerful, reliable illumination in demanding environments. Its clear tubular design delivers the characteristic warm amber light associated with HPS technology, making it a strong choice for large-area and outdoor lighting where high lumen output and efficiency are important.

This lamp is intended for use in appropriately rated luminaires equipped with compatible SON control gear (ballast and ignitor). It is not suitable for direct connection to mains or for use with standard household dimmers. Expect a brief warm-up period to reach full brightness.

Typical applications include street and road lighting, floodlighting, perimeter and security lighting, industrial sites, warehouses, and car parks. Always verify fixture compatibility and follow local regulations for installation and end-of-life disposal.
