A high-pressure sodium street light in Toronto A high-pressure sodium-vapor lamp An HPS lamp that isn't entirely off. A sodium-vapor lamp is a gas-discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm. Two varieties of such lamps exist: low pressure, and high pressure.
The most common type of floodlight was the metal-halide lamp, which emits a bright white light (typically 75–100 lumens/Watt). Sodium-vapor lamps are also commonly used for sporting events, as they have a very high lumen to watt ratio (typically 80–140 lumens/Watt), making them a cost-effective choice when certain lux levels must be provided.

Diagram of a high-pressure sodium lamp A high-pressure sodium lamp, Philips Master SDW-T 100W. Various types of chemistry are used in the arc tubes of HID lamps, depending on the desired characteristics of light intensity, correlated color temperature, color rendering index (CRI), energy efficiency, and lifespan.
Streetlamp with a ceramic metal halide bulb Ceramic metal halide bulb with G12 socket. A ceramic metal-halide lamp (CMH), also generically known as a ceramic discharge metal-halide (CDM) lamp, [1] is a type of metal-halide lamp that is 10–20% more efficient than the traditional quartz metal halide [2] and produces a superior color rendition (80-96 CRI).
Flood watches that affected millions across southeastern Florida have ended but a watch remained in place for nearly 1.5 million people along eastern Florida through the evening.
Note 9] In 1977 it was the most powerful light in Florida. [2] In the 21st century it has been claimed that the beam from the Hillsboro Inlet Light is the most powerful in the world. [Note 3] Automated in 1974, the light acts both as a coastal navigational aide and as a support to local water traffic.
