High Pressure Sodium (HPS) lamps are a type of discharge lighting that produce a bright, yellow-orange light. Known for their energy efficiency and long lifespan, they are commonly used in street lighting, parking lots, and industrial applications. HPS lamps have a high luminous efficacy but lower color rendering compared to other lighting types like metal halide.
Metal Halide lamps for aquariums are high-intensity lighting systems designed to provide the intense, full-spectrum light needed for coral growth and vibrant underwater plant life. These lamps emit bright, white light with a high Color Rendering Index (CRI), mimicking natural sunlight. They are especially popular in reef aquariums for their ability to penetrate the water and support photosynthesis in corals and other marine life.
Protected Pulse Start Metal Halide (PSMH) lamps feature a pulse-start ignition system for quick, reliable starts and higher light output. The “protected” outer glass envelope shields the lamp, improving durability and color stability. These lamps are commonly used in commercial, industrial, and outdoor applications for consistent, high-quality illumination.
Standard Metal Halide (MH) lamps are a type of high-intensity discharge (HID) lighting that produce bright, white light by passing an electrical current through a gas-filled arc tube containing metal halide salts. They offer good color rendering but have slower start-up times and less efficiency compared to pulse-start versions. These lamps are commonly used in street lighting, warehouses, sports arenas, and other large spaces requiring high illumination.
