The Superlec Direct 150SE 150 Watt Elliptical External Ignitor Lamp is generally used in industrial areas, such as low bay fittings and security lighting.
Elliptical coated lamps provide less glare and have a high colour rendering ability.
The 150 Watt High pressure sodium lamp provides a broader spectrum of light in comparison to the low pressure version, and should be installed into an enclosed fitting.
