Sylvania 400W E40 HSI-E Lamp, 4200K

The Sylvania HSI-E 400W E40 discharge lamp is a metal halide light source designed for technical and professional lighting applications that require high power and reliable color rendering.

Lighting for Large Spaces and Professional Facilities

This discharge lamp is the ideal choice for illuminating large areas in industrial settings, warehouses, gyms, and sports facilities. With a luminous flux of 40,000 lumens and a color temperature of 4200K (natural white), it ensures optimal visibility and natural color rendering. The E40 base allows for quick installation on standard lamp holders, while the 360° omnidirectional light distribution ensures uniform coverage of the space.

HSI Light Source for Workplaces and Retail

Technical lighting systems in stores, showrooms, and workspaces benefit from the 4200K light quality, which highlights details and supports concentration. The color rendering index (CRI) of over 70 renders colors naturally and accurately, a critical factor for sectors such as retail, manufacturing, and services. HSI discharge technology offers Class B-certified energy efficiency, reducing energy consumption compared to traditional solutions.

Reliability and Durability in Continuous-Operation Applications

With an estimated average lifespan of 36,000 hours, this light source minimizes maintenance and replacement costs in systems that operate continuously. The robust housing, measuring 120 mm in diameter and 290 mm in length, is designed to withstand demanding environments, ensuring stable performance over time. Ideal for fixed lighting systems in warehouses, covered structures, loading areas, and high-traffic zones.

Power Supply Specifications and Compatibility

The lamp operates at 120V and requires a specific power supply (driver/transformer) compatible with HSI light sources. It is not dimmable and is therefore suitable for systems with standard on/off control. The E40 base ensures compatibility with fixtures and lamp holders commonly used in the professional technical lighting sector.
