Compact ultraviolet (UV) lamps are used in many industries and applications in fluorescent-type lamps as well as UVC germicidal, low-pressure mercury lamps. Plug-in lamps with pin sockets come in various sizes and lengths, such as long (PLL) and short (PLS). PLS lights are used in many environments such as accentuating modern architecture, lighting solutions for homes, offices, exterior signs, and security.

Low-pressure mercury compact PLS lights provide germicidal solutions in many applications, killing bacteria, viruses and harmful microorganisms in water, in the air, and on surfaces.

PLS Compact Fluorescent Lampspls light

Lamp manufacturers offer PLS lamps which are a type of compact fluorescent lamp, also known as CFL bulbs, or energy-saving bulbs. PLS light is becoming more popular and a common lighting choice due to its high performance from a smaller, cost-efficient fluorescent lamp with long life performance. PLS fluorescent lamps are typically available with 2-pin or 4-pin bases with a range of options in emissions and color temperatures from daylight to warm white lighting.

CFL bulbs contain a phosphor coating inside the glass tube which produces UV light when electricity mixes with mercury and argon gases. The fluorescent coating reacts with the UV light to produce visible light, which may start off dim and become brighter.


UVC PLS Light for Germicidal ApplicationsUVC pls light

Ultraviolet radiation in the UVC range, specifically at 254 nm, is proven highly effective at eradicating many types of harmful microorganisms, including viruses, bacteria, mold, mildew, and others. UVC lamps designed to emit 185 nm produce ozone, another proven sterilizer, and oxidizer. There are countless sterilization systems that utilize UVC lamps for cleaner air, water, and surfaces. Many of these sterilization systems require high UVC output in a small space.

UVC PLS lamps provide germicidal effectiveness in a smaller, cost-efficient compact lamp solution.

We offer prototype development and manufacturing solutions, following a strict quality policy as part of our ISO9001:2015 certification. CFL lamps from LightSources are engineered to emit 90% of total rated UVC energy to maintain the most effective germicidal wavelength for effective sterilization.

Compact UVC lamps from LightSources are found in sterilization systems worldwide, including air and water purification, surface sterilization and the food and beverage industry. Germicidal lamps help to purify the air and remove airborne diseases and contaminants with UV air sterilization systems popular in hospitals, industrial air treatment, and even HVAC units in residential homes.

UV water treatment purification systems help to eliminate many viruses in the water, some that even chlorine cannot kill. Water treatment systems utilize UVC germicidal lamps for wastewater treatment, industrial water treatment, fish and marine life, drinking water, pool and spa, ballast water treatment in ships and many other water treatment systems.

You can find UVC lamps in many surface sterilization systems, including UVC robots, germicidal lamps used to sterilize medical equipment and surfaces, hospital rooms, operating rooms, research laboratories, and more. Even small handheld devices and little robots to roam across countertops use compact UVC lamps to prevent harmful microbial buildup and the spread of contagious diseases.
